Electronic Fuel Injection – The Reason Behind Its Adoption Over Carburetors

EFI or the Electronic fuel injection is a modern concept to cars, and that is undoubtedly giving the vibes of confusion especially to first-time car owners. You may always think of either getting a carburetor or an EFI based car. Carburetors are like traditional fueling system that was popular before 1980. After this period, electronic fuel injection took place and replaced the tradition. The reason behind that is simple; a carburetor was not good enough to pass the fuel/air to a four-cylinder engine.

As a solution, the concept of twin-carburetors came and unfortunately that too did not fit. EFI came into the picture to make the process efficient and give the engines a powered theme.

Types Of Fuel Injection – Mechanical And Electronic Fuel Injection

The smoky and poisonous effect of the carburetor was another reason that EFI overcame for being less toxic and noisy. EFI provides high-pressure fuel delivery and there are mainly two types mechanical and electronic that we are going to talk here.

Let us focus on the same and have a clearer understanding.

1. Mechanical One

The mechanical injector was famous around 1970 as being a previous invention to electronic fuel injection. In the mechanical injector, the fuel passing mechanism works when the high pressure makes the fuel pumped and get into the fuel collector. It reaches to the fuel distributor which then passes to the fuel injector and then to the inlet port.

It works reasonably well keeping the fuel/air mixture balanced. All in all, the mechanical controls are used to control the air/fuel mixture and to maintain the emission. For cold starting, injecting of extra fuel is needed, and in a mechanical system, it is done by an extra injector mounted in the manifold.

2. Electronic One

An electronic fuel injection as its name implies works on a complex microprocessor control unit or the ECU. The miniature computer comes with all the info fed by default and works as per the sensors depict the necessity. The requirements vary each time as per the air pressure, temperature, and engine speed and hence the system performs to deliver the fuel and air accordingly. You can browse online to get the best maintenance tips for keeping your car running to its maximum capacity.

Cold starting gets easier with an electronic injector where the sensors deliver the fuel necessity of the moment. As a result, the fuel gets passed to the inlet port making it a rich combination of fuel/air. Once the engine heats up, the connection automatically gets disconnected, and you can operate your car right away. This entire process takes place less than half of a second on bestowing your engine with better fuel efficiency.

Conclusion

The electronic fuel injection comes added up in modern automobiles as it donates to less environmental harm plus better fuel transfer. However, even while having advanced technologies EFI can often face problems and most of these take place due to the blocked injector or dirty fuel.

EFI too comes with maintenance requirements just like a mechanical EFI or the carburetor. One can easily identify the symptoms when the EFI goes low on performance poor fuel economy is a sign. Hence, you can go with EFI over carburetor if you are ready to take your car for regular checkups.

    Maybe it is in the translation, but I feel several concepts and explanation between the two systems is lost here. However, I do enjoy the articles/blog.
