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.

The system pumps more fuel than is needed for injection – a loop injectio returns the excess to the fuel tank via a pressure regulator which keeps the pressure in the pipes constant. Fuel injection is gradually replacing carburetors in these nations too as they adopt emission regulations conceptually similar to those in force in Europe, Japan, Australia, and North America.

A special pump sends the fuel under pressure from the fuel tank to the engine bay where, still r57 pressure, it is distributed individually to each cylinder. This computer is fed with information from sensors mounted on the engine. There are several competing objectives such as:. During the s, other mechanical injection systems such as Hilborn were occasionally used on modified American V8 engines in various racing applications such as drag racingoval racingtuel road racing.

Another early use of gasoline direct injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in Once the engine has warmed up to a certain temperature, a thermoswitch automatically cuts off the cold-start injector. The Ultimate 20 injecton car mechanics video course Learn everything about modern cars from our new video series.

All share the central task of supplying fuel to the combustion process, but it is a design decision how a particular system is optimized. Scania fordonshistoria in Swedish.


Porsche racing variants such as the RSR 2. Air pollution from motor vehicles; standards and technologies for controlling emissions. In a common rail system, the fuel from the fuel tank is supplied to the common header called the accumulator.

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.

The circumferential velocity component is first generated as the propellant enters through helical or tangential inlets producing a thin, swirling liquid sheet. The fuel is sprayed with the help of a nozzle that is opened and closed with a needle valve, operated with a solenoid.

Modern diesels only change the amount of fuel injected to vary output; there is no throttle. Excerpts from the Rambler Rebel Owner’s Manual “. The valve only opens when the fuel is squirted in.

Propeller governor Propeller speed reduction unit Spinner.

A typical system is the Bosch LJetronic, which is fitted to a wide range of European cars. The functional objectives for fuel injection systems can vary. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

How Gas Compression-ignition Engines Work. Injectkon the s, the Isuzu Piazza and the Mitsubishi Starion added fuel injection as standard equipment, developed separately with both companies history of diesel powered engines.

Automobile emissions control Catalytic converter Diesel particulate filter Exhaust manifold Glasspack Muffler. From the metering unit, the fuel is delivered to each of the injectors in turn.


The most common automotive continuous injection system is Bosch’s K-Jetronicintroduced in The first automotive direct injection system used to run on gasoline was developed by Boschand was introduced by Goliath for their Goliath GP automobile, and Gutbrod in InLucas developed its injection system, which was first used for Jaguar racing cars at Le Mans.

It needs fuel, air oxygen, to be precise and spark in order to operate. There is either a separate injector for each cylinder or one or two injectors into the inlet manifold. This system directed the inducted engine air across a “spoon shaped” plunger that moved in proportion to the air volume.

Since the fuel passes through the intake runners like a carburetor systemit is called a “wet manifold system”. Archived from the original on The fuel injection system in petrolengined cars is always indirect, petrol being injected into the inlet manifold or inlet port rather than directly into the combustion chambers. The justification for single-point injection was low cost. Single-point injection SPI uses a single injector at the throttle body the same location as was used by carburetors.

Each injector contains a spring-loaded valve that is kept closed by its spring pressure. One solution is to fit twin-carburettors, but these are difficult to tune correctly.

The first post-World War I example of direct gasoline injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in Because of the presence of the gas core, the discharge coefficient is generally low.
