Question: 1 / 550

What is the primary function of fuel injection in an engine?

To replace the carburetor

The primary function of fuel injection in an engine is to provide precise and efficient delivery of fuel into the combustion chamber, which generally replaces the older carburetor system. Fuel injection systems atomize the fuel, allowing for a more controlled and efficient combustion process. This leads to better engine performance, improved throttle response, and often enhanced fuel efficiency compared to carbureted engines.

In modern aircraft engines, fuel injection helps to provide the correct fuel-air mixture across varying operating conditions, which is critical for maintaining optimal performance. While fuel injection may contribute to fuel efficiency and reduced emissions, as well as potentially providing additional power during certain phases of flight, its overarching role is to replace the carburetor and ensure more precise fuel management.
