How does the electronic fuel injection system work?

How does the electronic fuel injection system work?

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. The EFI system basically has the same diagrams as conventional fuel systems. However, the EFI system does not equip with carburetor.

What kind of fuel does a mechanical fuel injection system use?

Mechanical fuel injection works well for naturally-aspirated or forced-induction engines and handles most any type of fuel — gas, ethanol blends, methanol, and even nitro blends. Setups can range from simple single-nozzle systems costing a few hundred dollars through to systems costing tens of thousands of dollars.

What are the groups in the fuel injection system?

There are two groups in the fuel injection system, namely fuel lines group (mechanical parts) and controller group (electronic parts). The injection system is used in almost all vehicles produced today. This is because the injection system has many advantages.

Where is the injector located in an EFI system?

The EFI system basically has the same diagrams as conventional fuel systems. However, the EFI system does not equip with carburetor. Instead, the injector will be placed in front of the intake valve in each cylinders.

What are the different types of fuel injection?

Over time, the point of injection has moved closer and closer to the cylinders themselves. The three major types of fuel injection are known as throttle body injection, multiport injection, and direct injection.

What is the difference between carburetor and fuel injection?

The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created by intake air accelerated through a Venturi tube to draw the fuel into the airstream.

What are the symptoms of a faulty fuel injector?

– Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart…

What is a bad fuel injector?

A car that has a bad fuel injector will often have a rough, or choppy, engine idle. A fuel injector is responsible for injecting fuel directly into the engine cylinder where it is burnt during combustion; if this fuel delivery is compromised, a rough engine idle can result.
