Working Of Electronic Fuel Injection System

As earlier said the fuel injector is an electronically controlled mechanical device that is. Electrical and electronic devices are used to monitor and control engine operation.

It gives the clear idea about how to work a fuel injection system.

Working of electronic fuel injection system. Types Of Electronic Fuel injection System. Principle and Working of Electronic Fuel Injection System 1. Now were going to dive into electronic fuel injection systems.

A modern gasoline injection system uses pressure from an electric fuel pump to spray fuel into the engine intake manifold. Once it finds what it likes it tells the injector to remain open and spraying fuel for a given length of time. Architecture of Electronic Fuel Injection System Sensors.

The computer then compares that data to a stored map of fueling requirements. We went over the different types and functions of carburetors in a previous episode. 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.

A solenoid on each injector controls the amount of fuel delivered by the injector. This video is the working principle animation of electronic fuel injection system. Electronic sensors to monitors different output such as exhaust gas temperature coolant temperature speed and throttle position.

Air filters to remove solid particles from the. Like a carburetor it must provide the engine with the correct air-fuel mixture for specific operating conditions. All modern vehicles are provided with a fuel injection system to convey fuel to the engine while reducing the amount of harmful emissions that a vehicle emits off.

Information about the engines operating state is conveyed to the computer via sensors. 1 The electronic fuel injection system relies on electronic signals that control how these items operate. Electronic Fuel Injection By DrSJohn Alexis 2.

Electronic Fuel Injection System 1. The electronic control unit ECU It controls ignition timing and quality of the fuel. These are the fuel delivery system air induction system and the electronic control system.

All electronic fuel injection systems work in essentially the same way. Thus the chambers combustion will occur correctly to obtain optimal motor power and environmentally friendly exhaust gases. Sensors are installed in numerous points of the engine and their function is to send out information to the ECU.

The Electronic Control Unit is responsible for the measurement of the sensors and the. Principle and Working of Electronic Fuel Injection System 2. This makes the gasoline injection system.

Electronic Fuel Injection is a fuel spray system that works electronically controlled so that the mixture of air and fuel always follows the fuel motors needs. The fuel then exits pressurized through the outlet port. The EFI engines run more smoothly with lower emissions and fuel.

The main working is from the fuel injector to the combustion chamber after fuel is pump to it from the fuel tank. The hydraulic electronic unit injectors use high pressure engine oil to provide the force needed to complete injection. Unlike a carburetor however PRESSURE not engine vacuum is used to feed fuel into the engine.

There are two groups in the fuel injection system namely fuel lines group mechanical parts and controller group electronic parts. Many of the mechanical drive components found in standard mechanical or electronic unit injection systems are not used in this system. Electronic Fuel Injection system is divided into three basic sub-systems.

The injection pumpfuel distributor assembly is driven by the timing belt chain or gears which in turn drives the fuel pump. 2 Along with checking a fuel injector electronically you can listen for certain kinds of sounds that will tell you when a fuel injector might not be working correctly. Modern automobiles use electronic fuel injection EFI in their fuel delivery system in order to increase the efficiency.

The working of a fuel injector system is quite interesting and easier to understand. Single-Point or Throttle Body Injection Port or Multi-Point Fuel Injection Sequential Fuel Injection Direct Injection. The vanes draw the fuel in through the inlet port then squeeze the fuel into a tight passage.
