Abstract: Apparatus and process for testing and analyzing the overall performance of an internal combustion engine by providing a simulated load to the engine. The simulated load is effected by periodically interrupting the engine ignition to reduce the total developed power of the engine to a value equal to the frictional horsepower at a desired speed. The period of the interruption cycle is controlled in response to the desired speed.
