Spark ignition engines--Misfire

found: Work cat.: Piernikarski, D. Investigation of misfire nature using optical combustion sensor in a SI automotive engine, 2000:abstr. (The paper describes investigations on the nature of the misfire phenomenon in a SI [spark ignition] engine. Authors performed a series of experiments on a single-point gasoline injection engine in a wide range of loads and rotational speeds, including different air-fuel ratios. The data was gathered using optical combustion sensor integrated with a spark plug)
