You can find and buy High Pressure Fuel Pump / Fuel Injection Pump of high High Pressure Fuel Pump / Fuel Injection Pump – HYUNDAI H Box D (57 . The last carburetor-equipped car came off the assembly line in Since then, fuel injectors have been the primary means of getting gasoline into the engine. For the engine to run smoothly and efficiently it needs to be provided with the right quantity of fuel/air mixture according to its wide range of demands.

Parallels to fuels other than gasoline can be made, but only conceptually. There is either a separate injector for each cylinder or one or two injectors into the inlet manifold. The Motorola technology was installed in Ford North American products.

W8 W12 W16 W It has no venturi, no pressure chambers, no diaphragms, and no discharge valve. The Bosch fuel injectors were placed into the bores on the cylinder wall used by the spark plugs in other Mercedes-Benz six-cylinder engines the spark plugs were relocated to the cylinder head. This makes it run more quietly than a mechanical system does. Petrol engines can use gasoline direct injectionwhere the fuel is directly delivered into the combustion chamberor indirect injection where the fuel is fhel with air before the intake stroke.

Mechanical systems have now been largely superseded by electronic fuel injection known as EFi for short.

The Factory Lightweight Legacy. These measure factors such as the air pressure and temperature in the air intake, the engine temperature, accelerator position and engine speed. There are several competing objectives such as:. Another early use of gasoline direct injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in This was a “port” injection where the injectors are located in the intake manifold, very near the intake valve.

It needs fuel, air oxygen, to be precise and spark in order to operate. L-Jetronic first appeared on the Porscheand uses a mechanical airflow meter L for LuftGerman for “air” that produces a signal that is proportional to “air volume”. NY State Journal of Medicine. Air filter Blowoff valve Boost controller Butterfly valve Centrifugal-type supercharger Cold air intake Dump valve Electronic throttle control Forced induction Inlet manifold Intake Intercooler Manifold vacuum Naturally aspirated engine Ram-air intake Scroll-type supercharger Short ram air intake Supercharger Throttle Throttle body Turbocharger Twin-turbo Variable-geometry turbocharger Variable-length intake manifold Warm air intake.

For the lay individual, the labyrinth of hoses, wire harnesses, manifolds and tubing beneath a car hood might appear intimidating. Please help improve this article by adding citations to reliable sources.

Propeller governor Propeller speed reduction unit Spinner. By using this site, you agree to the Terms of Use and Privacy Policy. Two common types exist: Depending on the particular system, the fuel is fired into either the inlet manifold or the inlet port via an injector.

With an assist from modern engine management computers, the fuel gets burned right where it’s needed, when it’s injecrion [source: The two most critical differences between a direct injection engine and a standard gasoline engine are how they deliver fuel and how the fuel mixes with incoming air.

Scania fordonshistoria in Swedish. Retrieved from ” https: Mechanical fuel injection was used in the s and s by many manufacturers on their higher-performance sports cars and sports saloons. The primary factor used in determining the amount of fuel required by the engine is the amount by weight of air that is being taken in by the engine for use in combustion.

Nissan also installed multi-point fuel injection in the Nissan Y44 V8 engine in the Nissan President.

These basic premises make a tremendous difference in an engine’s overall efficiency. The TCM system is even more simple. The injectors spray gasoline into the air intake manifold, where fuel and air mix together into a fine mist.

The limited production Chevrolet Cosworth Vega was introduced in March using a Bendix EFI system with pulse-time manifold injection, four injector valves, an electronic control unit ECUfive independent injecyion, and two fuel pumps. Fuel injection introduces potential hazards in engine maintenance due to the high fuel pressures used.

Finally, the homogeneity of the fuel mixture allows for leaner air—fuel ratios, which together with more precise ignition timing can improve fuel efficiency. Because of the presence of the gas core, the discharge coefficient is generally low.

While a simple carburetor system is cheaper to manufacture than a fuel injection system, the more complex carburetor systems installed on many engines in the s were much more costly than the earlier simple carburetors.
