What is the primary purpose of fuel injectors in a marine engine?

Fuel injectors play a critical role in the operation of a marine engine by ensuring that the correct amount of fuel is delivered to the combustion chamber. This precise delivery is essential for achieving optimal combustion, which enhances performance, efficiency, and overall engine health. By atomizing the fuel and mixing it with air at the right ratio, fuel injectors facilitate a more complete and efficient combustion process. This, in turn, helps to maximize power output while minimizing fuel consumption.

In addition, the proper functioning of fuel injectors directly impacts emission control and engine responsiveness. When fuel injectors operate effectively, they help maintain the ideal balance of air-fuel mixture, which is crucial for reducing harmful exhaust emissions and ensuring compliance with environmental regulations. Overall, the primary purpose of fuel injectors is to ensure that the engine receives the correct fuel amount for efficient combustion, making option C the most accurate answer.
