A Study on Ion Current and OH Radical Luminescence Behavior in a Two-Stroke Engine 2000-01-1424

In this research, an investigation was made of ion current and OH radical luminescence behavior in the progression from normal combustion to knocking operation. One pair each of an ion probe and a quartz observation window was fitted in the center and on the end of the combustion chamber. The peak values of the ion voltage drop and the OH radical emission intensity both increased as the cylinder head temperature and the cylinder pressure rose. It is possible to understand combustion conditions by analyzing measured waveformes of the ion voltage drop and the OH radical emission intensity.
