Abstract
Engine anti-idling and restart may be implemented in a machine having a power source, a movable work tool, a pump driven by the power source, an actuator receiving fluid from the pump and moving the work tool, a high-pressure fluid reservoir, and an assist motor operatively connected to the power source. Engine restart may include detecting operator input to start the power source, and fluidly connecting the fluid reservoir to the assist motor to assist in starting the power source in response to detecting the operator input. Prior to shutting down the power source during anti-idling, fluid from the pump may be input to the assist motor, pressurized and communicated to the high-pressure fluid reservoir in response to determining that idle condition exists and a reservoir charge pressure is less than a reservoir minimum restart pressure needed to restart the power source.
