What Is Electronic Fuel Injection

EFI does exactly what it sounds like. Electronic fuel injection replaces the need for a carburetor that mixes air and fuel.

The final piece in the fuel injection puzzle is appropriately enough the fuel injector.

What is electronic fuel injection. In contrast to that actual engines 100 of the cars and about 90 of the motorcycles sold nowadays are using Electronic Fuel Injection. 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. Originally hated as computer-controlled carburetors EFI gained reliability in the 1980s and picked up performance in the 1990s.

It injects fuel directly into an engines manifold or cylinder using electronic controls. The injector operates by allowing a very specific amount of fuel into the combustion chamber via computer. 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.

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. We went over the different types and functions of carburetors in a previous episode. In case of EFI the fuel is injected into the intake manifold using the so called injectors which can be imagined as a.

Usually the injectors have two pins. These systems are most common in automobiles and trucks. 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.

Thus the chambers combustion will occur correctly to obtain optimal motor power and environmentally friendly exhaust gases. 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. Electronic fuel injection EFI replaced carburetors back as the 21 Air Charge Temperature ACT preferred method for supplying air and sensor fuel to engines.

The number of fuel injectors and types. However injecting it at the optimal moment and in optimal quantity is far from easy. Electronic Fuel Injector Unit Injector.

Now were going to dive into electronic fuel injection systems. Injecting fuel into the fuel valve is a necessary process in any combustion engine. Fuel injection systems supply fuel directly to the cylinders of a vehicles engine.

A variety of nozzle designs and engine optimisation injection strategies are employed by electronic common-rail injection systems that cover the wide range of. One pin is connected to the battery through the ignition relay and the other pin. Electronic fuel injection EFI is interesting tech critical to the performance of a modern engine.

Todays impressively powerful vehicles are possible through direct fuel injection. The ECU sends. A vacuum-powered fuel pressure regulator at the end of the fuel rail ensures that the fuel pressure in the rail remains.

This intake manifold is found ahead of the cylinders in most fuel injected engines. While the auto industry has been enjoying the technology for decades its not as common in smaller engines. EFI System has almost completely replaced usage of carburetors.

Electronic fuel injection is a type of technology and mechanical structure that supplies fuel to an engine. Electronic fuel injection systems are a great way to meet these standards and vastly increase performances.
