TORQUE SIGNAL DETECTING DEVICE FOR INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To obtain the torque signal and carry out an exhaust gas recirculating control in a high accuracy by a method wherein an operating circuit having a characteristic to obtain a constant torque for every opening degree of an accelerator is provided in this device. CONSTITUTION:A signal from a memory circuit 1, memorizing the revolving number of the engine is inputted into the operating circuit 2. The operating circuit 2 compares and operates the opening degree signal of the accelerator or the output of a potentiometer 3 and outputs the torque signal corresponding to the output torque of the engine. This torque signal is inputted into an exhaust gas recirculating control unit 4 together with a revolving speed signal and whereby the level of NOX contained in the exhaust gas may be controlled correctly under a perdetermined value. Thus, the exhaust gas recirculating control may be carried out in higher accuracy.
