What is the difference between carburetors and electric fuel injectors?
Home » Automobiles » Fuel Injection » What is the difference between carburetors and electric fuel injectors?A carburetor mixes the fuel and air before intake into the engine. This is called emulsifying the gasoline. An electronic fuel injection system injects the fuel into the engine while it is a liquid. When we think of the essential ingredients in the operation of an engine, we automatically think of fuel. However, air is essential as well, regardless if the fuel is emulsified or not. Air causes the fuel to be oxidized, which generates heat and in turn, causes the engine to run. The means by which air is directed in an electronic fuel injection system is more efficient than a carburetor simply because the electronic fuel injection system's components are smaller. The fuel-to-air ratios - and how they are controlled--have a direct effect on efficiency, emissions and power of the engine. The bottom line is that the fuel- to-air ratios are less effectively controlled with carburetors and much more effectively controlled with electronic fuel injectors.
