Engine control device

Abstract

Abstract PURPOSE:To reduce vibration caused by irregular combustion and prevent the occurrence of a torque shock by detecting the load variations of first and second engine mount members by means of their respective pressure detecting parts and detecting the occurrence of said irregular combustion from their respective differences. CONSTITUTION:Loads which act on first and second mount members 18, 19 for supporting an engine body 10 are detected by their respective pressure sensors 23, 24, and their variation quantities are outputted via load detecting signal forming parts 23a, 24a. A control unit 100 receives their respective signals SR, SL and calculates the differences in their respective load variation quantities. In the case of an ordinary operating condition, the differences are small since the load variations are generated at the same ratio with the raggedness of a traveling road surface, whereas, when the differences are large, it is judged that an irregular combustion occurred and an air fuel ratio is controlled so that irregular combustion may not occur. Thereby, the occurrence of irregular combustion can be securely detected without effecting an erroneous action due to the ruggedness of a traveling road surface.
