Abstract:
An engine load estimating apparatus, including an actuator that changes a position of a top dead center of a piston of the engine, and a controller in communication with the actuator. The controller detects a drive output of the actuator when the actuator changes the position of the top dead center of the piston, and estimates the load of the engine based on the detected drive output of the actuator.
