Therefore, a car normally carries only a few minutes of nitrous oxide, and the driver uses it very selectively by pushing a button. No other way are you going to be able to add more than 100 hp for less than a thousand bucks, all in an afternoon's work. That's enough to push a 12-second street car deep into the 11s and potentially into the 10s. The only problem with nitrous oxide is that it is fairly bulky, and the engine needs a lot of it. The company Nitrous Oxide Systems (NOS) was born. If the throttle body is mounted lower than the inlet valves, for instance, then the mixture will have problems reaching the engine. For this particular system to operate, the engine must be at wide open throttle. Wet injection: A wet nitrous kit sees the nitrous oxide injected into the combustion chamber simultaneously with additional gasoline (or other fuel) through the same plate or nozzle that supplies the fuel. To make sure that doesn't happen, we recently had a chat with Kyle Smith of Nitrous Oxide Systems. check out for more What is NOS for cars? Introduction to NOS: How nitrous oxide injection makes more - YouTube Dry injection: This system works by using the existing fuelling system (either carburetted or fuel injected), to supply the gas or diesel while the nitrous is injected into the intake separately. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. You need to provide more fuel for the additional oxygen released from the N2O mixture to safely combust, or you will actually have a lean reaction and cause premature detonation, or pinging. Cars with nitrous-equipped engines may be identified by the "purge" of the delivery system that most drivers perform prior to reaching the starting line. In the context of racing, nitrous oxide is often termed nitrous or NOS. Finding the right fit for your car depends on your resources, budget and tuning capabilities. ", A common mistake for nitrous newbies is using the wrong type of spark plug. Its earliest uses were as an anesthetic before German engineers in World War II used it to enhance the performance of airplanes at high altitudes. A fitting is selected based on the desired power output. Nitrous works in more than one way, but primarily it all adds to the same effect. When nitrous is injected into an engine, it results in an increase in the fuel being added, too. NOS is legal to use in some classes of auto sports. How Nitrous Oxide (NOS) in Car Works | dubizzle When a mole of nitrous oxide decomposes, it releases half a mole of O2 molecules (oxygen gas), and one mole of N2 molecules (nitrogen gas). Nitrous oxide systems were applied as early as World War II for certain aircraft engines. The ideal heat range of a plug depends on the application and amount of nitrous used. Avoid trying to cheat the fuel pressure regulator into giving more fuel too. Heres how. As a strong spark is always needed, a full overhaul of the ignition system is also required. As the decomposition of N2O into oxygen and nitrogen gas is exothermic and thus contributes to a higher temperature in the combustion engine, the decomposition increases engine efficiency and performance, which is directly related to the difference in temperature between the unburned fuel mixture and the hot combustion gasses produced in the cylinders. Language links are at the top of the page across from the title. Alternately, the EFI system's computer can be re-tuned to increase fuel flow as well. This oxygen supports combustion; it combines with fuels such as gasoline, alcohol, diesel fuel, propane, or compressed natural gas (CNG) to produce carbon dioxide and water vapor, along with heat, which causes the former two products of combustion to expand and exert pressure on pistons, driving the engine. Two particles of nitrogen for every particle of oxygen give nitrous oxide the chemical formula of N2O. - Easy to abuse The nitrous will only inject when at full throttle, using a micro switch fitted either under the accelerator pedal or on the throttle body. These systems will either start off small and finish with a big shot of N2O (typically a naturally aspirated engine) or start off big (for example, to get the turbo spooling) and end with smaller shots as the engine relies more on the turbo. When nitrous enters the nozzle, it turns into a gas, 36% of which is oxygen. A Nitrous Oxide Engine, or Nitrous Oxide System commonly referred to and known as NOS, is an internal combustion engine in which oxygen for burning the fuel comes from the decomposition of nitrous oxide, N 2 O, as well as air. This particular setup activates nitrous when the engine is at wide open throttle. Nitrous Bottle A bit self explanatory, this tank holds the N2O pressurised in liquid form. A direct-port nitrous system, on the other hand, relies on injector nozzles plumbed directly into each individual intake runner. Being that direct port systems do not have to rely on intake tract/manifold design to evenly distribute the nitrous or fuel/nitrous mixture, they are inherently more precise than other delivery methods. "The biggest advantage of a dry system is that the operator has ultimate control of the fuel delivery at nearly any point in the run. The nitrous oxide changes from liquid to gaseous, which cools the air in the system and allows more oxygen to enter the engine. Installing a nitrous system might not take a whole lot of time, but that doesn't mean any bonehead with his own set of wrenches is up for the job. Many people refer to it as NOS (an acronym for Nitrous Oxide Systems), but this is actually the brand name of a company, much like many people refer to tissues as Kleenex. Reliable operation of an engine with nitrous injection requires careful attention to the strength of engine components and to the accuracy of the mixing systems, otherwise destructive detonations or exceeding engineered component maximums may occur. ", In a typical V-8 application, upgrading to a forged rotating assembly is very good idea when nitrous levels exceed 150 hp. Because of the heat in the engine, the nitrogen and oxygen molecules split; the sudden increase in . Well, if you're a dentist, you'll know that nitrous oxide is commonly referred to as laughing gas. You decide: In summary, a nitrous oxide system has many benefits for drag racing and almost none in other forms of motorsport (although there are some exceptions). The most important add-on of all; traction control for nitrous. Like Coke and Xerox, the company has been around for so long that "NOS" has evolved into a generic name racers often use to describe all nitrous systems. It also is for on demand use only. How Does it Work? This extra oxygen allows the engine to burn more fuel which increases power. Get 6 issues of Performance VW for only 18, Car Tuning: How To Performance Tune An Engine, What Is Car Detailing? The effort paid off, as NOS quickly became known for producing easy-to-install kits made from the highest quality material available. Many nitrous cams have wider lobe-separation angles than naturally aspirated engines, but the exhaust valve opening and closing points are more important than LSA figures. For more car engine information, check out the links on the next page. Photos: Chris Wallbank. What Is Nos In Cars? - Answer-Wheel.autos Nitrous oxide does not break down into nitrogen and oxygen until it reaches 572 degrees Fahrenheit. Engineering Explained: How NOS Works - Car Throttle "The increased horsepower capability of plate nitrous systems in recent years stems from plates being built with multiple sets of spray bars or diffusers combined with larger orifice solenoids. Performance brakes are also a necessity as many underestimate how much nitrous will actually improve the performance. What is NOS and how does it work? - Overdrive iOS: https://apple.co/1QyKDskGoogle Play: https://bit.ly/21hRHwaClick the link^ to get their app and supp. Obviously where things get technical. In both a plate and direct-port nitrous system, a mixture of nitrous oxide and fuel is injected into incoming air intake charge. ", Many street/strip nitrous applications utilize a separate fuel cell that feeds the nitrous system. Types of Nitrous Systems Are Cars With NOS Susceptible to Damage? The purpose of a nitrous purge is to ensure that the correct amount of nitrous oxide is delivered the moment the system is activated as nitrous and fuel jets are sized to produce correct air / fuel ratios, and as liquid nitrous is denser than gaseous nitrous, any nitrous vapor in the lines will cause the car to "bog" for an instant (as the ratio of nitrous / fuel will be too rich reducing engine power) until liquid nitrous oxide reaches the injection nozzle. This generally results in failure as it either doesnt make power or melts the engine. If there is no single shared throttle body or carb then this kit cant work either. + Can be easily disabled and uninstalled, leaving almost no evidence Now that the oxygen atom is isolated, it is freed up to be used in combustion. When, exactly, depends on all sorts of variables, like bottle size and pressure, jet sizes, delivery method (fixed or progressive), and how often it's used. Other brand names include Nitrous Express (NX) and ZEX - but these are all the same thing. For example, in New South Wales, Australia, the Roads & Traffic Authority Code of Practice for Light Vehicle Modifications (in use since 1994) states in clause 3.1.5.7.3 that The use or fitment of nitrous oxide injection systems is not permitted.[2]. + Traction control alternative for high-power drag cars, The Cons Complete kits can be bought for less than$500 . How It Works - Nitrous Oxide Systems - MotorTrend Guide To Car Washing At Home, R56 Mini Buyers Guide & Most Common Problems To Look Out For, Best Alloy Wheel Cleaners 2023: Group Test. This allows for a greater amount of fuel to be added and converted into energy. Along that vein, you could say a nitrous piston will likely be a little heavier, have the top ring moved down a little, and have more spacing between the ring lands if possible," Kyle explains. In wet systems the high pressures of the nitrous injected causes the aerosolization of the fuel injected in tandem via the nozzle, allowing for more thorough and even distribution of the nitrous/fuel mixture. Firstly, it contains around 16 per cent more oxygen than air. When the liquid nitrous is released from the canister and expands into a gas, it cools and thus becomes denser, and once in the combustion chamber, the oxygen splits from the nitrogen allowing for more fuel and preventing premature detonation. Nitrous oxide systems, also known as NOS, may be permitted for use depending on local city regulations. Nitrous Oxide in Cars - Exotic Whip What does nitrous oxide do to a car? Secondly, nitrous is a liquid that boils to become a gas. The expanded components exert pressure on the pistons, which then drives the engine. A car that runs purely off a nitrous oxide engine is rare and will typically require frequent rebuilds. The use of nitrous oxide carries with it concerns about the reliability and longevity of an engine present with all power adders. That said, the timing chart is included with every new NOS brand systems and that is also available on our website has a very good timing chart that explains recommended timing requirements, and how you go about determining what is best for your combination. In normal atmospheric conditions, it turns to gas. As the name suggests, this is simply a nitrous kit (wet or dry but normally the former) that uses only one injector to inject the mixture into the intake system. The bad raps come from its ability to be concealed, leading others to believe there are no additional power-adders. But how does it work and why does it improve performance. Direct port nitrous systems will use the same or similar nozzles as those in single nozzle systems, just in numbers equal to or in multiples of the number of intake ports of the engine. Essentially, the basic reason to inject nitrous oxide is to increase the amount of oxygen in the combustion chamber, allowing for more fuel. Nitrous Oxide Systems' Double Cross system ups the ante even more with a plate design that incorporates spray bars intersecting at a 90-degree angle. NOS: Nitrous oxide - International Motor Show Nitrous works in more than one way, but primarily it all adds to the same effect. Installation of a turbocharger, on the other hand, provides horsepower without needing a refill and is not used on demand. The ideal timing for a given combination is dependent on many things," says Kyle. Port and direct fuel injection engines have intake systems engineered for the delivery of air only, not air and fuel. Its the fuel thats the problem to get right, so these injectors are designed to give a crossfire spray pattern which is better for atomization of the two substances. NOS can increase engine power from 1 hp to several hundred, depending on vehicle performance and modifications. For carbureted or throttle body applications, the most common type of system involves a spray bar plate that fits between the carburetor or throttle body and the intake manifold. This is an area that most any inexperienced nitrous user is going to need help. There are other ways of increasing power, but few are as cheap and easy to implement (albeit, if the engine can handle it). It gives your engine more oxygen to burn, which in turn allows more fuel to burn creating more power. Progressive systems have the advantage of utilizing a larger amount of nitrous (and fuel) to produce even greater power increases as the additional power and torque are gradually introduced (as opposed to being applied to the engine and transmission immediately), reducing the risk of mechanical shock and, consequently, damage. Thus, purging is necessary before use to ensure that only gas is being injected. Dry nitrous systems offer tuning advantages as well. In the early 2000s, a movie called The Fast and the Furious hit our screens and introduced many to the import tuner culture and cars with NOS. "While mixing different types of fuel in the combustion chamber is not ideal, it has become common," says Kyle. But how does it work, how does it compare to turbocharging, and where to buy nitrous oxide for cars? Nitrous oxide, also known as laughing gas, is two parts nitrogen and one part oxygen or N 2 O if you prefer chemistry. This fitting is installed between the nitrous/fuel lines and the fitting connecting to the nitrous plate solenoids. They tap into the cars fuel supply near the inlet manifold and therefore rely on the standard fuel pressure and pump. When the heat in the cylinder from the combustion process reaches around 550 degrees F, the nitrous gas will disassociate into its two parts; nitrogen and oxygen. Sensors, relays, and wires are used to connect to the throttle position sensor as well as solenoids on the nitrous plate. Wet nitrous systems can be used in all four main delivery methods. How Does Nitro Boost (Nitrous Oxide) Work in Cars? | Car Part Every hot rodder knows that nitrous oxide injection kits add silly heaps of horsepower for not a lot of money, but why is it so effective? "Oxygenated fuels, such as Q16, are generally not suggested for nitrous motors, except possibly for jet-limited classes. These sorts of systems mean you don't have to use your brainjust your footand beat any sort of steering-wheel-mounted push-button. However, it was quickly picked up by the large and popular drag racing communities across America in the search of power. In a dry nitrous system the nitrous delivery method provides nitrous only. What Is Nitrous, and How Does It Work? - The News Wheel It also allows a much bigger dose; increased air speed at higher speed and rpm means the nitrous is more diluted with air, and therefore capable of consuming more. "Maintaining a constant pressure is one of the most important aspects of tuning a nitrous system for proper performance, and 950 psi is considered the ideal operating range. Nitrous oxide can work on any car, or any engine. This causes a car to slow, or in the worse case scenario, damages parts. A: Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). It was only during the Second World War that its massive performance-enhancing abilities were recognized. There are solenoids for both N2O and fuel, which inject when the engine is operating at wide open throttle. Clever versions have extras such as recognizing what gear youre in and increasing the dosage it injects throughout the gear. "While there are no hard and fast rules about what needs to be done, high levels of nitrous require certain concessions to be made," says Kyle." Use your head, though, install your system thoughtfully, be realistic when it comes to power goals, and your nitrous-induced engine can last for years. Multiple "stages" of nitrous can be accomplished by using multiple sets of nozzles at each intake port to further increase the power potential. - YouTube 0:00 / 0:00 ESTADOS UNIDOS How Nitrous Oxide works // 3D animation. No. 1. This extra oxygen creates additional power by allowing more fuel to be burned. [image: dry nitrous nozzle][image: nos nitrous oxide injector spray plate][image:direct port nitrous wet nozzle]. When the purge system is activated, one or more plumes of nitrous oxide will be visible for a moment as the liquid flashes to vapor as it is released. Dependent on application, plate systems can provide precise nitrous or fuel/nitrous mixture distribution similar to that of direct port systems. "Octane is not the only consideration when choosing a race fuel, but also the formulation of the fuel is very important as well. How Does Nitrous Work? NOS In Cars| JEGS - JEGS High Performance The heat range of a plug refers to the temperature of the ceramic material surrounding the electrode. A bar nitrous system utilizes a hollow tube, with a number of holes drilled along its length, placed inside the intake plenum to deliver nitrous. Considering the latest crop of plate systems are now capable of adding 500 hp, what are the advantages of a direct-port system? This kit is just like a single injector set up but uses four injectors instead; one for each cylinder. At this point it is still a controlled burn so the increase in oxygen and heat rapidly speeds up the combustion process by increasing the flame speed and reaching peak temperature more quickly. It combines with the additional fuel to create extra heat and pressure, increasing the amount of power the engine generates. The amount of horsepower it provides is dynamic throughout the rpm range when comparing a nitrous vs turbo setup. "So when you're injecting nitrous, you gotta make sure you match that with the correct amount of fuel," Sullivan says. These are designed to give even flow and ensure theres no chance of pressure drop. Wizard Of Nos (WON) have fitted kits to everything from diesels to Ferraris and even chainsaw engines. How does nitrous work? Once you've got your needs figured out, you can decide to go with a single nozzle nitrous kit, spraying the gas into the intake, or multiple smaller nozzles for each cylinder or bank of cylinders, depending on the application. The extra fuel required is introduced through the fuel injectors, keeping the manifold dry of fuel. A plate nitrous system uses a spacer placed somewhere between the throttle body and intake ports with holes drilled along its interior surfaces, or in a tube that is suspended from the plate, for the nitrous or fuel/nitrous mixture to be distributed through. However, turbocharger setups are more expensive, costing two to four times as much as a nitrous setup, or more. Engines run on oxygen and fuel. While thinking creatively about Nitrous Oxide in Cars, the name of the famous action movie 'Fast & Furious' must have already crossed your mind. What's the cheapest way to increase horsepower? The - MotorTrend By installing two sets of solenoids, a dual-stage system allows limiting nitrous flow off the line to enhance traction, and then increases nitrous flow once a car is farther down the track. Nitrous injection is a form of forced induction like turbocharging or supercharging. It was sometimes used with the Luftwaffe's form of methanol-water injection, designated MW 50 (both meant as Notleistung short-term power boosting measures), to produce substantial increases in performance for fighter aircraft over short periods of time, as with their combined use on the Focke-Wulf Ta 152H fighter prototypes.[3]. Contrary to popular belief, if your car is topping out at 140mph, NOS is not a necessity. Heres what you need to know. Its benefits arent over yet though. Large bottles can also be rented to reduce the number of trips to the gas supplier as well. But before fitting, its important to ensure your car and engine are in good condition which includes things that will take the added strain, such as the clutch. Nitrous oxide (also known as dinitrogen monoxide or dinitrogen oxide in geek speak) works by introducing extra oxygen into the intake charge. 7 Things You Need to Know Before Purchasing Your First - EngineLabs Both turbocharged and naturally aspirated engines can benefit from this, and it can be used on supercharged cars too. Last updated Dec 22, 2020 0 comments Nitrous oxide in cars has always been popular as an inexpensive performance booster. "There really is no such thing as a nitrous piston' per say, but the real question is whether or not the piston is durable enough for the power level you are about to subject it to. Since the spark plugs must maintain a certain temperature to stay clean, using plugs with the wrong heat range can result in plug overheating or fouling. A similar basic technique was used during World War II by Luftwaffe aircraft with the GM-1 system to maintain the power output of aircraft engines when at high altitude where the air density is lower. That signal can be as simple as you flicking a switch as soon as you realize the Camaro in the other lane is all of a sudden beating you or as complex as pre-programmed throttle, vehicle speed, or rpm parameters you set within whatever engine tuning package you've got. More informatio. Plate systems are usually wet, meaning the spray plate releases both fuel and nitrous into the intake. As long as you keep this in mind with the tune-up you shouldn't have any issues. However, you will need to properly transfer the gas from the large cylinder to the bottle that will be in your vehicle. Dry systems cant be used on engines with carbs. Likewise, direct-port nozzles put the mixture directly in the path of the intake valve for quicker response on the bottle. This will depend on the application, but each has its benefits and drawbacks. The simple rule is to make sure the valve is at the very highest point it can be. According to NOS, however, that doesn't always make it a good choice for heavy-duty nitrous applications. Despite the hoards of racers jumping on the forced induction bandwagon, nitrous remains one of the most devastatingly effective and incredibly affordable performance modifications in existence. Some hot rodders feel this type of setup is completely safe while others think it's risky, so who's right? For this reason, its easier and cheaper to install and it will come in more progressively. Its kinder to the drivetrain, helps acceleration times and is more efficient. We know it as NOS. The AWD Chevy Corvette E-Ray Has a Cheat Code for Burnouts. However, determining how much the ignition timing should be reduced is based on multiple factors, including compression ratio, nitrous volume, spark plug heat range, fuel type and compression ratio. To allow the pressurised nitrous to reach the engine, the kit relies on solenoids to open that are triggered electronically. Once there, a sensor receives a signal from the TPS sensor that signals for the fuel and nitrous solenoids to open up, allowing for flow. This allows you to lean out or richen up the nitrous/fuel mixture point during a pass at the dragstrip, depending on track conditions," says Kyle. The more of both at the proper ratio, the more power, until mechanical failure, that is. Typically, a four-cylinder engine using a 100-shot with the factory-supplied bottle can get away with about 20 squeezes before having to refill it all over again. Just remember that your stock EG Honda Civic was never designed to run on the gas and you may lose your car if you're caught with a nitrous system on the road. Additionally, many late-model engines run leaner air/fuel ratios than older muscle cars, which require larger plug gaps and a projected plug nose to help ignite the air/fuel mixture. Hot and cold days both have an effect on the bottle pressure, so this will help to stabilize it. "If the pressure falls off too fast during a run, the system will go rich, since the nitrous system will continue enriching the air/fuel mixture even though the flow of nitrous has been reduced. ", Although mild doses of nitrous oxide are perfectly safe to use in a stock engine, NOS recommends loosening up internal clearances for race engines built specifically for large volumes of nitrous. "I agree with that premise and once heard a engine builder say, Would you rather hammer on your crank and block with a steel hammer, or an aluminum hammer?'". about: Supercharger vs Turbocharger [Power, Fuel Economy, Pros & Cons], about: Quick Power Gains: How to Increase Horsepower & Engine Performance, about: How to Assemble AN Fittings and Hose Assemblies, Shop All Nitrous Oxide Systems And Components. They work by pulsing the solenoids on and off to increase or decrease nitrous flow. How Does Nos Work In A Car - Quick Answer - The Car Blog For carbureted or throttle body applications, the most common type of system involves a spray bar plate that fits between the carburetor or throttle body and the intake manifold. When NOS is injected into the engine, it increases the amount of oxygen available to the combustion process, which allows the engine to produce more power. Tanks store nitrous oxide in its liquid state. This brings liquid nitrous oxide all the way up through the plumbing from the storage tank to the solenoid valve or valves that will release it into the engine's intake tract. Like any gas, it takes up a fair amount of space even when compressed into a liquid. Longer and larger internal-diameter lines mean more chance of pressure dropping, temperature increasing and turning into gas before it reaches the cylinders. To avoid unwanted nitrous from leaking into the system, a check valve or solenoid is a valuable addition to avoid the aforementioned issues that come with failure to purge, but purging is still recommended.
