Abstract: Knock affects the engine's
performance and efficiency in a negative way.This paper discussed the knock
phenomenon of the Coal-Bed Gas Engine,the mechanism of knock combustion,the
test of knock processor and the method of use the knock processor to detect the
engine knock combustion.At last, proposed a real-time closed loop control
strategy to the spark timing the engine knock phenomenon of the al-bed gas
engine ignition shockof technology.
Keywords: Coal-bed Gas Engine;Knock
Detection;Knock Process Chip;Control Strategy
