Combustion engine controller determines the change in torque for each firing cycle and uses such data for statistical processing to determine the combustion roughness, further used in optimizing engine performance

摘要

Device has a change in torque calculation device for determination of the torque change every firing stroke and a combustion roughness determination device for calculation of the combustion roughness so that it can be used display of the engine combustion state by statistical processing of the change in torque. Such processing only uses data from a pre-set valid torque change data range.
