Abstract
An engine on an excavator provides power to a hydraulic pump that pumps hydraulic fluid under pressure to a hydraulic actuator. The hydraulic actuator is controlled to place a load on the engine. Engine response to the load placed on it by the hydraulic actuator is detected and logged. The logged engine response data can be accessed to identify engine response.
