What Electronic Fuel Injection

EFI does exactly what it sounds like. This intake manifold is found ahead of the cylinders in most fuel injected engines.

Electronic fuel injection EFI replaced carburetors back as the 21 Air Charge Temperature ACT preferred method for supplying air and sensor fuel to engines.

What electronic fuel injection. Architecture of Electronic Fuel Injection System Sensors. Electronic fuel injection EFI is interesting tech critical to the performance of a modern engine. The number of fuel injectors and types.

Sensors are installed in numerous points of the engine and their function is to send out information to the ECU. A variety of nozzle designs and engine optimisation injection strategies are employed by electronic common-rail injection systems that cover the wide range of. A type of electronic fuel injection system that uses a single injector or pair of injectors mounted in a centrally located throttle body.

Electronic fuel injection EFI Electronic fuel injection allows for extremely precise control over how much fuel is sprayed into the cylinders. Originally hated as computer-controlled carburetors EFI gained reliability in the 1980s and picked up performance in the 1990s. All these terms refer to the newer generation Petrol Injection systems.

Fuel is sprayed directly into the throttle bore s by the injector s. We went over the different types and functions of carburetors in a previous episode. A basic EFI system will consist of an electronic control unit - ECU - a fuel pump to deliver the required fuel pressure fuel injectors and several sensors.

The fuel exits the fuel tank via the fuel pump. Fuel injection is a system that supplies a vehicles fuel directly into the cylinders of into the intake manifold of the engine eliminating the need for a carburetor. It injects fuel directly into an engines manifold or cylinder using electronic controls.

Fuel injection systems supply fuel directly to the cylinders of a vehicles engine. While the auto industry has been enjoying the technology for decades its not as common in smaller engines. Electronic fuel injection is a type of technology and mechanical structure that supplies fuel to an engine.

The throttle unit resembles a carburetor except that there is no fuel bowl float or metering jets. EFi stands for Electronic Fuel injection EFi whereas MPFi or MPi stands for Multi-Point Fuel injection and GDi stands for Gasoline Direct Injection. It follows a fairly straightforward process to do so.

Electronic Fuel Injection EFI - Engine Management-----Summary of VideoThis sect. These systems are most common in automobiles and trucks. The Electronic Control Unit is responsible for the measurement of the sensors and the.

All these are the types of fuel injection systems which the gasoline or petrol fuel engines mainly use. Todays impressively powerful vehicles are possible through direct fuel injection. Now were going to dive into electronic fuel injection systems.

The basic difference is To measure the temperature of the air that a carburetor uses intake vacuum and entering the motor a pressure drop in the venturi the narrow part of the carburetor throat to siphon fuel from the carburetor fuel bowl into. Electronic fuel injection replaces the need for a carburetor that mixes air and fuel.
