Electronic Fuel Injection System Layout

Basic System Overview opens spraying atomized fuel at the back side of the intake valve. The EFI system basically has the same diagrams as conventional fuel systems.

Common Diesel Fuel Injection System Architectures

5 As fuel is sprayed into the intake air stream it mixes with the incoming air and vaporizes due to the low.

Electronic fuel injection system layout. Functional Requirements of An Injection System i. This system consists of the unit injectors fuel manifolds electronic pressure regulator high pressure fuel pump electronic control unit wiring harness and engine sensors. Accurate metering of the fuel injected per cycle.

An FI system consists of three primary components. Process of fuel injection. The central- injection unit operates at low pressure 07 to 1 bar so.

A modern gasoline injection system uses pressure from an electric fuel pump to spray fuel into the engine intake manifold. And other advantages are. The quantity of the fuel metered should vary to met changing speed and load requirements of the engine ii.

It is the same purpose as the carburettor choke. The electronic fuel injection system is a new innovation in gasoline engine this system incorporates electronic computerizm to get the best fuel and air comparisons under all engine conditions. We review the popular different options for EFI Fuel Systems and help choose the best.

Ever wondered how to setup a fuel system for electronic fuel injection. The precise controls the fuel injection system has over the carburetor allow. Circuit on and off.

Application of advanced electronic injection systems. The kit comes with an ECU capable of learning the. Iv To atomise the fuel for quick ignition.

A Servojet electronic fuel injection system was designed and manufactured for the Cummins VTA-903 engine. The fuel pump is usually placed inside the fuel tank itself and its. The injector is flushed.

This helps the engine to start up in very cold weather. Overview When it comes to injection systems there are a number of systems capable of fueling a Rover 216CID small block engine. Better flow due the elimination of the venturiof the carburetor.

What is Electronic Fuel Injection System EFI A system which aims at optimizing fuelair ratio entering a vehicles engine is referred as Electronic Fuel Injection System. A fuel pump fuel injectors and an ECU. Better atomization of fuel.

An inexpensive hydrodynamic electric fuel pump can be used generally in the form an in-tank unit. The electronic fuel injection system has a cold start injector too. Like a carburetor it must provide the engine with the correct air-fuel mixture for specific operating conditions.

To obtain maximum power ensuring fuel economy and clean burning iii. 4 When the injector is turned on it 8. EFI System has almost completely replaced usage of carburetors.

Fuel injection system is a mechatronic circuits that combine mechanical and electronic circuits to achieve a common goal that is to supply fuel to the intake manifold with ideal volume. Timing the injection of the fuel correctly in the cycle. The main functions of fuel injection system are.

Lower emissions of pollutants. Page 4 Electronic Fuel Injection System 3 The ECU pulses the injector by 7 Reduces HC and CO pollutants switching the injector ground emission. Direct - In jected DI in the case of 2 - stroke engines and Port - Injected PI in the case of 4 - stroke engines.

Injector nozzle breakage and leakage problems were solved. Unlike a carburetor however PRESSURE not engine vacuum is used to feed fuel into the engine. Advantages of Electronic Fuel Injector.

A company in the US called FAST have created a system known as EZ-EFi which is a self learning fuel injection system consisting of a large four barrel plenum fitted to a custom manifold. There are two groups in the fuel injection system namely fuel lines group mechanical parts and controller group electronic parts. However the EFI system does not equip with carburetor.

Electronic Fuel Injection System 1. I To measure the correct amount of fuel required by engine speed and load ii To maintain correct timing for beginning and end of injection iii To inject the fuel into the combustion space against high compression pressure. This makes the gasoline injection system.

Electronic Fuel Injection By DrSJohn Alexis 2. Using injectors fuel injection pump fuel filter and fuel lines is called fuel injection system. It is an extra injector that sprays fuel into the centre of the engine intake manifold to start the engine easily.

Instead the injector will be placed in front of the intake valve. Electronic injection system Advantages of electronic injection system over carburetor. Throttle Body Injection is an electronically controlled injection system in which an electronic fuel injector injects the fuel intermittently in to the intake manifold at a central point ahead of the throttle valve.
