Nitrous oxide kits are illicit for accepted street and highway convenience.
NOS, which stands for nitrous oxide systems, consists of the chemical formula of two parts nitrogen and one apportionment O2. When NOS is used as a supplemental Gauze in an internal combustion engine, it dramatically raises combustion compel finished increased fuel burning, which raises horsepower. Nitrous oxide systems are used on the flying performance and racing circuits, allowing racing aficionados to install custom kits on their vehicles. Any racing fanatic should sense what NOS can engage in for a vehicle, and how it functions.
NOS Basic Function and Theory
After nitrous oxide becomes heated to environing 572 degrees F during the compression stroke, it transforms and adds O2 molecules to the fuel mix. The added O2 allows else textbook of fuel to burn. When the pressurized O2 is injected into the intake transaction, it transforms from a liquid to a Gauze and then boils. The reaction causes a hyper-cylinder combustion and raises cylinder pressures, which adds exceeding authority to the compression stroke, raising both rpm and horsepower.
Direct Port NOS
Regulate Harbour NOS systems deliver a combination of nitrous and fuel directly into Everyone seperate engine intake Harbour. A nozzle, or fogger, is used to merge and metre the combined fuel to Everyone cylinder. A distribution block and solenoid valves administer the fuel to the fogger by the cause of connecting tubes.The nitrous oxide becomes misted by a fogger Slogan in regulate Harbour systems, or atomizes, then enters the intake manifold and onto the cylinders.
Dry NOS
A dry nitrous action transports the nitrous fluid on ice the inventory fuel injection step. The common fuel supplies the leading potentiality, while the nitrous oxide supplements it for increased burning. The upper intake remains dry of fuel. A solenoid meeting allows more pressured flow of nitrous on ice the fuel lambaste along with the public fuel. The vehicle machine can and add fuel jotter via incremental adjustments, which pushes also fuel into the intake.
Wet NOS
Wet NOS systems encompass the apply of a typical nozzle to inject fuel and nitrous oxide into the sincere air intake. The wet type NOS systems delivers nitrous and fuel at the identical generation, usually 3 to 4 inches ahead of the throttle thing for fuel-injected systems, or condign under the carburettor complete a carburettor plate. With wet NOS systems, the upper intake remains wet with fuel. Wet systems are most commonly used on wet flow and turbo or supercharged vehicles.
The Proceeds of nitrogen atoms in the brew has a cooling backwash on cylinder temperatures, thus acting as a governor, to edge intolerably high rise ignition temperatures and pressures.
Basic NOS Components
The source of nitrous oxide requires a high-pressure bottle -- sometimes two or aggrandized -- to influence the fluid chemical. The fluid moves fini high-reaching compel lines to a fuel regulating Slogan and then onto a overhaul Harbour that introduces the nitrous oxide into the cylinders, via a dry, wet or govern Harbour injection course.The residence of the nozzle depends upon its position on Everyone intake runner, and this changes by engine replica. Because the injection of the fuel and nitrous is directed into identical cylinders, the ratio of Everyone can be adjusted fini jetting for Everyone cylinder without affecting the other cylinders. This adjustment-metering makes the conduct Harbour NOS model accurate.
Direct Port NOS Complexity
The direct port NOS system most often requires drilling, extra plumbing and tapping for customized fits to free up any flow restrictions, making it the most complicated out of the three types. Direct port NOS systems are among the most powerful kits for the highest horsepower and performance gains, typically seen in race cars. Because of the increased demands on the engine, direct port NOS usually requires several aftermarket performance parts, like high-output fuel pumps, maximum flow fuel filters and high-energy ignition systems with timing retard features.
NOS System Gains and Applications
A NOS kit typically lowers intake charge temperatures by approximately 60 to 75 degrees. Generally, a 1 percent increase in horsepower is gained for every 10 degree drop in intake charge temperature. For instance, a 70-degree drop in temperature will produce approximately 25 more horsepower in a 350-horsepower engine. Kits are available for any performance enhancement, ranging from low to very high horsepower gains.
NOS Installation Benefits and Applicability
NOS kits offer the best money expenditure for the most effective high-performance modification on vehicles. In most cases, for installation and calibration, the systems require nothing more than hand tools and instruction literature. Nitrous oxide control activation is determined by the driver, as to when and how often he uses it. The vehicle runs normally on its own fuel source when the nitrous control switch is off. Nitrous systems work well, adaptable to computer-controlled, fuel-injection systems. Nitrous systems can be removed and utilized on other vehicles, with some minor adaptations and re-calibration.
NOS Warnings
Nitrous oxide kits must be installed on vehicles that can accommodate them, without exceeding maximum performance, torque and horsepower recommendations. High-performance NOS applications can put undue strain and stress on transmissions, drive lines, engine rods, cams, crankshafts, axles, bearings and suspension parts. Improperly installed and tuned NOS kits can cause catastrophic engine breakage and failure. NOS systems that have been installed with inferior parts can leak, causing serious flammability issues. Improperly handled pressurized nitrous bottles can burst and explode from mishandling and severe temperature fluctuations. Any person wishing to install and use NOS should thoroughly read the literature on the kit before installation.
