Question

Quizplus · Accepted Answer

Diesel engine breathing efficiency is defined as the actual volume of air taken in during the intake stroke versus cylinder swept volume. This is important because the more air the engine can take in, the more fuel it can burn and the more power it can produce. In other words, the more efficiently the engine can breathe, the better its performance will be.
