Introduction to Fuel Injection Technology
Fuel injection engines represent a revolutionary leap in automotive technology, offering unprecedented precision, efficiency, and performance compared to traditional carburetor systems. For automotive enthusiasts and DIY mechanics, understanding and implementing fuel injection can transform an ordinary engine into a high-performance powerhouse.
What is a Fuel Injection Engine?
A fuel injection engine is a sophisticated system that delivers fuel directly into an engine’s combustion chamber or intake manifold with electronic precision. Unlike carburetors, which rely on mechanical fuel mixing, fuel injection systems use sensors and computer controls to optimize fuel delivery.
