A power management system for a combustion engine is disclosed. The power management system has a fuel injector, a sensor, and a controller in communication with the sensor and the fuel injector. The fuel injector is operable to inject multiple shots of fuel into the combustion engine during a single injection event. The sensor is configured to sense a speed of the combustion engine and generate a signal indicative of the sensed speed. The controller is configured to limit the number of shots per injection event in response to the signal.

A hydraulic valve with hydraulically assisted opening comprises a valve body that defines a fluid passage which includes an upstream segment and a downstream segment. Contained within the valve body is a moveable valve member which includes a hydraulic surface. The hydraulic surface is exposed to fluid pressure within the downstream segment of the fluid passage. When the valve member is in a closed position, the upstream segment of the fluid passage is closed to the downstream segment. The upstream segment is fluidly connected to the downstream segment when the valve member is away from the closed position.
