Abstract
The purpose of this study is to demonstrate cyclic variation of the combustion state including misfiring in a small two-stroke engine, focusing on the in-cylinder pressure variation and the gas constituent concentration at the exhaust port of the cylinder. It was found that the in-cylinder pressure at one point timing when its standard deviation became maximum value would be useful instead of indicated mean effective pressure (IMEP) in cycle-to-cycle varied combustion states. The cyclic variations of the CO and CO2 emissions were demonstrated by the fast-response exhaust gas analyzer. The features of the pattern of cyclic variation of the CO and CO2 emissions were similar to those of the IMEP. The difference level of CO and CO2 emissions between the two successive cycles depended on the IMEP.
