Diesel engines: open combustion chamber air motion statement Statement: In open combustion chambers of diesel engines, the piston-crown shape and the inlet port/valve layout are designed to generate strong swirl/turbulence of the air–fuel mixture for better mixing and combustion. Decide whether the statement is correct.

Difficulty: Easy

True
False

Correct Answer: True

Explanation:

ConceptOpen (undivided) chambers rely on air motion (swirl, squish, and tumble) created by piston-crown geometry and port/valve layout to atomize and mix the injected fuel rapidly, promoting fast, efficient combustion.

Final AnswerTrue
