Measurement of automotive vehicles power in real road conditions

A portable engine test bench makes it possible to measure power and torque, acceleration of given speed, breaking distance, and distortions of the speedometer reading. The operation principle of a portable test bench is similar to that of a stationary load test bench with the only difference that the vehicle testing takes place in real road conditions, not in simulated ones, on the rollers of a stationary engine test bench. In this work, the operation principle of the portable engine test bench, the measurement method and exemplary results that have been obtained from carried out experimental test have been presented which provides the basis for further measurements of the vehicle operation real parameters in real not laboratory conditions.
