Development Combustion

In recent years, abnormal combustion with high peak firing pressure has been experienced on gas engines with high brake mean effective pressures. The abnormality is detected not as pre-ignition but as knocking. Research, including visualisation tests on a single-cylinder engine, has confirmed the phenomenon to be pre-ignition caused by the auto-ignition of in-cylinder lubricant, causing cyclical variations of peak firing pressure on premix combustion gas engines.

Gas Engine Progress

The thermal efficiency of gas engines has improved considerably in the last decade with some gas engines achieving higher efficiency than diesel engines. This is based on advanced technologies including lean burn combustion, the Miller cycle and advanced electronic control systems [1], [2], [3]. However abnormal combustion has been detected, especially on engines with high brake mean effective pressure (BMEP). This is a type of pre-ignition that occurs when ignition timing is advanced by some degrees, but...
