Why Fuel Injectors are Better Than Carburetors

Carburetors are now a thing of the past with the emergence of fuel injection. The latter is better than the former in all facets that is why it is very popular today.

It is said that if automakers are asked why they replaced carburetors with injectors, the answer would be is that they are complying with government regulations regarding emission. But another good answer would be is that fuel injectors are far better than carburetors.

With the advent of car electronics, automakers favor fuel injection system over carburetor because the former can be easily controlled by the onboard computer. With more and more new car models being equipped with advanced computer systems, it was only a matter of time before the carburetor with its float, needle valve, and other components are phased out.

Another advantage of using a fuel injection system is that it injects atomized fuel into the combustion chamber. This reduces the problem of cold starting in engines. In engines equipped with carburetors, this problem is overcome by using the choke where an extra rich air and fuel mixture is fed into the cylinders. On fuel injectors controlled by computers, starting on a cold weather has become much easier.

In multiport fuel injection, another advantage of this system over the carburetor is very evident. In this setup, each cylinder has its own injector. With that setup and the computer controlling it, the fuel injection delivers a more balanced fuel into the cylinder compared to the blend delivered by a conventional carburetor.

Also, with a complete guidance from the onboard computer, the fuel injectors can spray the fuel mixture into the right cylinder at the right time. This means the engine can deliver more power while being more efficient. When it is delivered for an optimum combustion, there is a lesser chance that there would be unburned gases emitted from the engine. This is the reason why the use of fuel injection system is one solution taken by automakers to make their vehicles more fuel efficient and more eco-friendly.

The early part of the fuel injector's life though is not all smooth sailing. Back then, it is more mechanical than carburetors. Because of their complexity, fuel injectors were rarely used back then because they are cost prohibitive. As is the case with most automotive parts like AC condensers, automakers plowed on with their research to make it more affordable.

The quest to make fuel injectors for gasoline engine more efficient is felt in Europe. German company Bosch created the first electronic fuel injection system which was used on the Volkswagen Squareback. Today, fuel injectors are pretty much the norm when it comes to fuel delivery system for gasoline engines. While it is enjoying popularity today, it can still be expected that automakers will still be looking for ways to make it even more efficient.
