Question

Quizplus · Accepted Answer

By increasing the inlet air pressure in CI (Compression Ignition) engines, the air-fuel mixture's density increases, leading to better mixing and more efficient combustion. This process reduces the conditions that lead to knocking, thus decreasing the knocking tendency.
