Abstract: An internal combustion engine includes a cam-actuated rocker arm assembly with a solenoid-actuated latch that provides for cylinder deactivation or variable valve actuation. The solenoid is in a position where its inductance varies significantly in relation to the position of a latch pin as it translates between latching and non-latching configurations. A sensor is positioned to monitor a current or a voltage in a circuit that includes the solenoid. The sensor data is analyzed to provide diagnostic information relating to the operation of the rocker arm assembly.

Abstract: Exhaust gas recirculation pump (30) for an internal combustion engine that includes an electric motor (32) disposed within a housing (36). A Roots device (38) is coupled to the electric motor (32) and includes a housing (40) defining an internal volume (42) in which rotors (44) are disposed and are connected to the electric motor (32). The electric motor housing (36) includes a coolant path (48) formed therein which extends from a coolant inlet (58) to a coolant outlet (78), both coupled to an engine coolant circulation system. The housing includes an oil path (108) formed therein. The oil path includes an oil inlet (110) extending to at least one oil outlet (112). The oil inlet and outlet are coupled to an engine oil circulation system wherein the oil path (108) lubricates bearings (100) and a transmission assembly (46) of the exhaust gas recirculation pump (30).

Abstract: A hydraulically-actuated device comprises a self-contained fluid reservoir comprising a tank for receiving a fluid, a reservoir port, and a flexible diaphragm. An actuation member comprises a hydraulically actuated piston in a cylinder. A pump case comprises an inlet port and an outlet port, the inlet port in fluid communication with the reservoir port, and the outlet port in fluid communication with the actuation member. A pump is within the pump case. The pump can be a reversible pump. The flexible diaphragm can flex in to the fluid reservoir when the pump transfers a fluid from the fluid reservoir to the actuation member and can flex away from the fluid reservoir when the pump transfers fluid from the actuation member to the fluid reservoir. The flexible diaphragm can hermetically seal a fluid within the fluid reservoir and have a second side in communication with atmospheric pressure.
