ABSTRACT:
The output shaft of an engine to be tested is coupled to a pneumatically controlled engine-turnover system. The output shaft is also coupled to a hydraulic pump of the gear type having an output line which is valve-controlled to vary its output hydraulic pressure to provide an adjustable load. The operator, by referring to an appropriate chart, can adjust the load on the engine to any desired horsepower output by adjusting the pump output pressure and the rotary speed of the engine output shaft.
