In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke. The need for advancing (or retarding) the timing of the spark is because fuel does not completely burn the instant the spark fires. The combustion gases tak… WebApr 9, 2014 · So what happens is they retarded the valve timing to make the valves open later and close later, this reduces peak cylinder pressures.
