Abstract
Cyclic variability limits the range of operating conditions of spark igniti on engines, especially under lean and highly diluted operation conditions. The cyclic combustion variations can be characterized by pressure parameter s, combustion related parameters, and flame-front related parameters. The c oefficient of variation (COV) in indicated mean effective pressure (IMEP) d efines the cyclic variability in indicated work per cycle.
