FUEL CONTROL SYSTEM FOR CAR ASSOCIATED WITH CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PURPOSE:To realize smooth engine operation continuously by solving the inherent characteristic of CVT (Continuous Variable Transmission) power feedout system that the speed will increase upon supply of power feed reduction command while employing the microprocessor technology. CONSTITUTION:In a car having CVT, an engine control circuit 100 will control fuel feed means 12 in accordance to the operating condition detecting signals such as the stepping angle alpha of an accelerator pedal 18, engine rotation NE, etc. The ratio of CVT14 is operated by CVT ratio controller 17 on the basis of the output torque T0 of torque sensor 19, the accelerator pedal step angle alpha, etc. Here, means for reducing the fuel flow to the fuel feed means lower than the fuel demand to be determined through fuel function means in accordance to the engine rotation NE upon deterioration of the system performance commanded by command means or the accelerator pedal 18 is provided to the control system.
