What is the purpose of a fuel injector?

• A. To mix air with fuel for combustion
• B. To filter impurities from fuel
• C. To deliver metered amounts of fuel to the combustion chamber
• D. To monitor exhaust emissions

Answer: (C)

The purpose of a fuel injector is to deliver metered amounts of fuel to the combustion chamber. This component plays a critical role in the fuel injection system of an engine by ensuring that the correct amount of fuel is injected at the right time, which is essential for efficient combustion. The injector atomizes the fuel, spraying it into the intake manifold or directly into the combustion chamber, allowing for a homogeneous mixture of air and fuel. This precise control over the amount of fuel helps optimize engine performance, improve fuel efficiency, and reduce emissions. Proper operation of the fuel injector is vital for the engine's overall functionality and efficiency.
