The angled cap is used to fit on small bore applications, or for cam clearance.
Angle-split connecting rods have the disadvantage that the upper part of the blind hole thread is located directly in the path of greatest stress.
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
