Förbränningsmotor för motorfordon

摘要

A combustion engine ( 1 ) for a motor vehicle, having electronic members ( 20, 23 ) with memory function for controlling the output torque of the engine at least in dependence on signals representing an injected quantity of fuel. Reference values of engine torque at different rev speeds are stored in the control members. A torque transmitter ( 24 ) detects and transmits to the control members a signal representing the current output torque. The control members compare the current torque with the stored reference value in order to determine whether the performance of the engine is normal.
