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.

During the s, other mechanical injection fhel such as Injecttion were occasionally used on modified American V8 engines in various racing applications such as drag racingoval racingand road racing. It works, but from an engineering standpoint, it leaves much to be desired, and it’s pretty wasteful. First, the fuel travels via pump from the fuel tank, through the fuel line and into fuel injectors that are mounted into the engine.

It then signals the on-off valve ig the injector to open and squirt fuel into the inlet port. The Bendix system is a direct descendant of the pressure carburetor. Split-single I2 V2 F2. Porsche racing variants such as the RSR 2. This was a “port” injection where the injectors are located in the intake manifold, very near the intake valve. The fuel injector injects liquid fuel into the intake air the location of the fuel injector varies between systems. The fuel then squirts out into the inlet port in the cylinder head.

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. During that time period, the vast majority of gasoline-fueled automobile and light truck engines did not use fuel injection.

The injectors spray gasoline into the air intake manifold, where fuel and air mix together into a fine mist. 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 The intake is only slightly wet, and typical fuel pressure runs between psi.

All share the central task of supplying fuel to the combustion process, but it is a design decision how a particular system is optimized. Most of the 35 vehicles originally so equipped were field-retrofitted with 4-barrel carburetors.

Lucas Service Training Centre. The flap sits beneath the control unit and rises and falls in response to airflow – as you open the throttle, the injrction from the cylinders increases onjection airflow and the flap rises. Mechanical fuel injection was used in the s and s by many manufacturers on their higher-performance sports cars and sports saloons. Two-stroke Four-stroke Injedtion Six-stroke Two-and four-stroke.

The amount of fuel sprayed is increased or decreased by a mechanical injfction electrical control unit – in other words, it is just like turning a tap on and off.

Due to the wartime ruel between Germany and Japan, Mitsubishi also had two radial aircraft engines using fuel injection, the Mitsubishi Kinsei kinsei means “venus” and the Mitsubishi Kasei kasei means “mars”. An early use of indirect gasoline injection dates back towhen French aviation engineer Leon Levavasseur installed it on his pioneering Antoinette 8V aircraft powerplant, the first V8 engine of any type ever produced in any quantity.

In duel continuous injection system, fuel flows at all times from the fuel injectors, but at a variable flow rate. From Wikipedia, the free encyclopedia.

Part of the Automobile series. NY State Journal of Medicine. As with continuous injection, timed injection can also be controlled either mechanically or electronically. This system was used on the hot-bulb engine and was adapted injectipn improved by Bosch and Clessie Cummins for use on diesel engines Rudolf Diesel ‘s original system employed a cumbersome ‘air-blast’ system using highly compressed air [ citation needed ].

Direct Injection Basics | HowStuffWorks

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. They are often called petrol injection PI for short and the fuel flow is controlled by a mechanical regulator assembly.

Archived from the original PDF on Components Propeller governor Propeller speed reduction unit Spinner. Unlike carburetor-based systems, where the float chamber provides a reservoir, fuel injected systems depend on an uninterrupted flow of fuel.

By using this site, you agree to the Terms of Use and Privacy Policy. The carburetor remains in use in developing countries where vehicle emissions are unregulated and diagnostic and repair infrastructure is sparse.

The amount of fuel injected is controlled by a flap valve located in the engine’s air intake. Archived from the original on German direct injection petrol engines used injection systems developed by Bosch from their diesel injection systems.

How Direct Injection Engines Work

This page was last edited on 20 Decemberat Then, that cylinder’s designated spark plug fires, igniting the chamber into a high-pressure, high-energy explosion. Since the fuel passes through the intake runners like a carburetor systemit is called a “wet manifold system”.

The engine had six electrically operated injectors and were fed by a semi-high-pressure circulating fuel pump system. Before we look inside the direct injection engine, let’s view a quick second in the life of a standard gasoline engine for a more complete look at the gasoline engine, check out How Car Engines Work.

May Learn how and when to remove this template message. The more consistent and predictable composition of the exhaust makes emissions control devices such as catalytic converters more effective and easier to design.

The EFI system was developed to satisfy stringent emission control requirements and market demands for a technologically advanced responsive vehicle.

But when it comes to the gasoline engine, just know this: This unit is driven from the camshaft and its job, as the name suggests, is to distribute the fuel to each cylinder, at the correct time and in the correct amounts. The circumferential velocity component is first generated as the propellant enters through helical or tangential inlets producing a thin, swirling liquid sheet. 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.

In piston aircraft engines, continuous-flow fuel injection is the most common type.
