Cylinder pressure vs crank angle

WebMar 9, 2024 · When the pressure build up becomes too great for the octane tolerance of the fuel the remaining fuel spontaneously explodes, sending shock waves through the moving bits and doing no useful work. You can control the pressure rise vs crank angle by varying the amount of spark timing.
