Abstract

See full text

The present invention, in one form, is an oiling system for an outboard engine and includes an oil tank and an oil pump located within the tank. A manifold is coupled to the oil pump, and the manifold includes a solenoid controlled valve. The solenoid controlled valve controls the flow of oil through the manifold. The manifold further includes a plurality of check valves in flow communication with the solenoid controlled valve. The check valves are in flow communication between the solenoid controlled valve and the engine cylinders. The oil system, in the one embodiment, further includes a pressure regulator in flow communication with, and downstream from, the manifold. An outlet of the pressure regulator in flow communication with the oil tank, and allows oil to flow from the manifold to the tank when pressure in the system exceeds a preselected pressure. The oil system also includes a fuel solenoid controlled valve coupled to receive oil from the manifold and to supply oil to the engine fuel system. The engine includes an electronic control unit (ECU) for controlling the manifold solenoid and the fuel solenoid. In one embodiment, the ECU controls opening of the manifold solenoid valve and the fuel solenoid valve based on engine revolutions per minute.
