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.

As well as improved control over injectikn flow, the electronic system also operates at lower pressure than a mechanical system – usually at around psi. One solution is to fit twin-carburettors, but these are difficult to tune correctly. By using this site, you agree to the Terms of Use and Privacy Policy.

The New York Times. To comply with the new regulations, automobile manufacturers often made extensive and complex modifications to the engine carburetor s. Fuel injection was in widespread commercial use in diesel engines by the mids. A throttle position inmection TPS provides this information.

Porsche continued using this system on its racing cars into the late seventies and early eighties. Excerpts from the Rambler Rebel Owner’s Manual “.

The circumferential velocity component is first fkel as the propellant enters through helical or tangential inlets producing a thin, swirling liquid sheet. Petrol engines can use gasoline direct injectionwhere the fuel is directly delivered into the combustion chamberor indirect injection where the fuel is mixed with air before the intake stroke.

Data representing the amount of power output desired by the driver sometimes known as “engine load” is also used by the engine control unit in calculating the amount of fuel required. Because of the presence of the gas core, the discharge coefficient is generally low.


Depending on the system design, the timing of when injector opens is either relative each individual cylinder for a sequential fuel injection SFI systemor injectors for multiple cylinders may be signalled to open at the same time in a batch fire system.

Scania fordonshistoria in Swedish. Furthermore, on spark ignition engines, direct fuel injection has the advantage of being able to facilitate stratified combustion which have not been possible with carburetors. A special pump sends the fuel under pressure from the fuel tank to the engine bay where, still under pressure, it is distributed individually to each cylinder.

German direct injection petrol engines used injection systems developed by Bosch from their diesel injection systems. Most fueo engines with the exception of some tractors and scale model engines have fuel injected into the combustion chamber.

Fuel injection

The injectors spray gasoline into the air intake manifold, where fuel and air mix together into fuek fine mist. The Ultimate 20 hour car mechanics video course Learn everything about modern cars from our new video series. The fuel injector injects liquid fuel into the intake air the location of the fuel injector varies between systems.

W8 W12 W16 W However, this was less efficient than the now common direct injection in which initiation of combustion takes place in a iniection often toroidal in the crown of the piston. With direct injection engines, fuel is squirted directly into the combustion chamber instead of hanging out in the air intake manifold. As with continuous injection, timed injection can also be controlled either mechanically or electronically. Later, more mainstream applications of fuel injection favored the less-expensive indirect injection methods.


All modeled in 3D We’ve created the most detailed 3D model ever produced so we can show you everything working. This section needs additional citations for verification.

Direct Injection Basics | HowStuffWorks

For cold starting, a choke on the dash or, on later models, a microprocessor control unit brings a special cold-start injector into operation, which injects extra fuel to create a richer mixture. The Mercedes-Benz W Formula 1 racing car engine used Bosch direct injection derived from wartime aircraft engines. From Wikipedia, the free encyclopedia. To find out more about what makes direct injection engines more efficient, move on to injectin next page.

5d7 this racetrack success, the Mercedes-Benz SLthe first production sports car to use fuel injection, used direct injection.

Gasoline fuel injector for Opel Astra F 1.7 D, 57 hp, station wagon, 1992

Often a fuel rail is used to divide the fuel supply into the required number of cylinders. The control unit simply uses a butterfly valve for the air, which is linked by a mechanical linkage to a rotary valve for the injectoin. Air filter Blowoff valve Boost controller Butterfly valve Centrifugal-type supercharger Cold air intake Dump valve Electronic throttle control Fuek 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.

This works much like the spray nozzle of a hoseensuring that the fuel comes out as a fine mist. May Learn how and when to remove this template message.
