FIELD: transport.
SUBSTANCE: engine crankshaft angular speed is measured two times at full throttle and definite gear in free run without and with reference cargo in flat horizontal site ruling out wheelspin to define torque characteristics. Then, engine crankshaft angular speed is measured two times at full throttle and definite gear in free acceleration without and with cargo. Cargo weight is defined as product of torque characteristic, square of gearbox gear ratio, square of main gearing gear ratio. square of final drive gear ratio into difference in engine crankshaft angular acceleration at full throttle and definite gear in free acceleration with cargo.
EFFECT: higher accuracy.
