Granted: 2021-12-23
Abstract: FIELD: engine technology.  
     SUBSTANCE: invention can be used in testing and technical diagnostics of machines. A method for determining the effective power of an internal combustion engine is that when testing under operating conditions, a vehicle with a manual transmission is prepared. Force converters (1) are installed in the engine supports. A crankshaft speed sensor (2) is mounted in the clutch housing, to which a measuring device (3) is attached. The engine is started and warmed up together with the gearbox to the nominal temperature, and then tests are carried out, during which the acceleration parameters are recorded. When conducting tests under operating conditions, the vehicle starts moving, increasing the speed until the top gear is switched on. The fuel supply system to the engine is installed, which ensures a minimum stable speed of rotation of the crankshaft when the vehicle is moving at the top gear. The maximum fuel supply is sharply turned on, with a period of 720 degrees of rotation of the crankshaft. The speed of rotation of the crankshaft and the forces arising in the supports are fixed until the vehicle reaches the maximum speed at the gear. In each measurement interval, the average speed of the crankshaft, the average force and the average torque on each support and the total torque on the supports are calculated. According to the obtained values of the total torque on the supports and the average speed of the crankshaft in each measurement interval, the effective engine power is calculated. An approximating dependence of the effective power on the measurement time is constructed, the maximum value is found on the resulting curve, which is taken as the nominal effective power of the engine under study.  
     EFFECT: reducing the complexity and increasing the efficiency of diagnosis.
