  • Method of measuring the power output of an automative vehicle engine on a roller testing bench
    Patent number: 4370883
    Abstract: This method of measuring the power of an automotive vehicle engine on a roller-type testing bench comprises selecting the vehicle velocity and/or the engine speed whereat it is desired to make the measurement; increasing the engine speed during a first acceleration phase up to the selected value, measuring at this value the power available at the wheels, accelerating the engine slightly above the selected value, then disconnecting the drive and engaging the neutral; and allowing the rollers to slow down while they drive the engine transmission by inertia in order to measure, during this second deceleration phase, the power lost in the transmission.
