Abstract: PURPOSE: A suction air amount clip method for an engine control system of a hot film air flow sensor is provided to prevent lowering of fuel efficiency or performance from wrong decision by deciding the wide open throttle range accurately. CONSTITUTION: Temperature of an exhaust manifold is compared with the first reference value in keeping specific rpm over the predetermined time during in controlling the fuel injection amount by applying the clip value(S1,S2,S3). The application of the clip value is released in case of the temperature of the exhaust manifold to be less than the first reference temperature, and the fuel injection amount is controlled according to the suction air amount(S4). The fuel injection amount control is stopped, and the fuel injection amount is controlled according to the clip value in case of exhaust manifold temperature to be more than the second reference value(S5,S6). Lowering of performance or fuel efficiency is prevented by deciding the wide open throttle range accurately.

Abstract: PURPOSE: A combustion pressure sensor which does not react to a weak knocking is installed in a cylinder block, and a signal detected by the combustion pressure sensor is compared with a signal detected by a knock sensor to prevent misoperation of the knock sensor. CONSTITUTION: A misoperation control device comprises a driving state detecting member(100) and an engine control member(200). The engine control member outputs a control signal to receive the detected signal from the driving state detecting member, and receives knock signal, combustion pressure and engine rpm signal. If the engine rpm is in a certain range, and the knock learning value is in a certain range, the ignition timing is converted into previous time to an advance ignition.
