The combustion chamber shape MOST-Likely to have a squish/quench area that causes movement (turbulence) of the air-fuel mixture and cooling of the gases to prevent abnormal combustion is:
A) hemi
B) wedge
C) pent-roof
D) scalene

Question

Quizplus · Accepted Answer

Wedge-shaped combustion chambers are designed to create a squish or quench area, which induces turbulence in the air-fuel mixture and helps cool the gases, thereby preventing abnormal combustion such as knocking or pre-ignition. This shape effectively pushes the mixture into a smaller space as the piston approaches top dead center, enhancing the mixing and combustion process.
