What is the function of engine baffles in a reciprocating engine?

The function of engine baffles in a reciprocating engine is to direct airflow and improve cooling efficiency. Engine baffles are strategically placed components that help guide the airflow around the engine cylinders. This airflow is essential for dissipating heat generated during the combustion process. By ensuring that the cooling air flows around each cylinder effectively, baffles help maintain optimal engine temperatures, which is critical for engine performance and longevity.

Good engine cooling is vital since excessive heat can cause engine components to deteriorate or fail. The baffles enhance airflow distribution, allowing the engine to operate within its designed thermal limits, ultimately preventing overheating and promoting efficient operation. Their role is not to increase fuel efficiency, reduce engine weight, or filter air; rather, their primary purpose revolves around managing the thermal management system of the engine.
