As Gale Banks collaborates with Comp Cams in the development of a new high-performance camshaft for the Duramax L5P engine, he explains how he analyzes each step in the 4-stroke process. He reveals why squish and swirl are so important to proper diesel combustion as well as valve timing, duration, and overlap. He also details why he prefers a stock piston over one with valve reliefs. This is the best information you’ll receive about diesel combustion outside of engineering school.
