FUEL INJECTION D57 PDF

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.

This makes it run more quietly than a mechanical system does. May Learn how and when to remove this template message. The ECU interprets data from input sensors to, among other tasks, calculate the appropriate amount of fuel to inject.

Single-point injection SPI uses a single injector at fule throttle body the same location as was used by carburetors. Lucas Service Training Centre. Many modern EFI systems use sequential MPI; however, in newer gasoline engines, direct injection systems are beginning to replace sequential ones. Only air is drawn into injectuon cylinder. The valve only opens when the fuel is squirted in.

The flap sits beneath the control unit and rises and falls in response to airflow – as you open the throttle, the ‘suck’ from the cylinders increases the airflow and the flap rises. Global Fuel Economy Initiative. With the improved cylinder-to-cylinder fuel distribution of multi-point fuel injection, injwction fuel is needed for the same power output when cylinder-to-cylinder distribution varies significantly, some cylinders receive excess fuel as a side effect of ensuring that all cylinders receive sufficient fuel.

Diesel fuel injector for Citroen Saxo D, 57 hp, 5 doors, Price: €

With their extremely fast response time, multiple injection events can occur during each cycle of each cylinder of the engine.

Instead, many cars are now being fitted with fuel-injected engines where the fuel is delivered in precise bursts. How Direct Injection Engines Work. This approach required additional sensors to measure the atmospheric pressure and temperature, to ultimately calculate “air mass”.

Many diesel engineshowever, use direct injection in which the diesel is injected directly into the cylinder filled with compressed air. Immediately following the war, hot rodder Stuart Hilborn started to offer mechanical injection for race cars, salt carsand midget racers[9] well-known and easily distinguishable because of their prominent velocity stacks projecting upwards from the engines on which they were used.

The injectors through which the fuel is sprayed are screwed, nozzle-first, into either the inlet manifold or the cylinder head and are angled so that the spray of fuel is fired towards the inlet valve.

How Fuel Injection Systems Work

The control unit simply uses a butterfly valve for the air, which is linked by a mechanical linkage to a rotary valve for the fuel. Stop wasting time on YouTube and get serious! Porsche racing injeftion such as the RSR 2. This page was last edited on 20 Decemberat In Rover fitted Lucas electronic fuel injection, which was based on some L-Jetronic patents, to the S-Series engine as used in the model.

The system uses tubes with poppet valves from a central injector to spray fuel at each intake port rather than the central throttle-body [ citation needed ]. Air pollution from motor vehicles; standards and technologies for controlling emissions. The New York Times. This was a “port” injection where the injectors are located in the intake manifold, very near the intake valve.

The Electrojector patents were subsequently sold to Bosch. There are several competing objectives such as:. A fuel injection system Fuel pump Fuel filter Fuel accumulator Fuel distributor Inlet tract Inlet manifold Injectors Cold-start injector Pip from petrol tank Return pipe to tank A fuel injection system Injdction cars use indirect fuel injection.

Gasoline fuel injector for Opel Astra F D, 57 hp, station wagon, Price: €

These basic premises make a tremendous difference in an engine’s overall efficiency. It is heated so much by compression that atomized fuel injected at the end of the compression stroke self-ignites. This was basically a specially lubricated high-pressure diesel direct-injection pump of the type that is governed by the vacuum behind an intake throttle valve. The solenoid lifts the needle valve from the valve seat, and fuel under pressure is sent in the engine cylinder.

Diesel fuel injector for Citroen Saxo 1.5 D, 57 hp, 5 doors, 1999

Engines so equipped are usually more efficient and more powerful than carburetted ones, and they can also be more economical, as well as having less poisonous emissions. Unsourced material may be challenged and removed. Following this racetrack success, the Mercedes-Benz SLthe first production sports car to use fuel injection, used direct injection.

Furthermore, on spark ignition engines, direct fuel injectjon has the advantage of being able to facilitate stratified combustion which have not been possible with carburetors.
