  • Exhaust gas recirculation valve contaminant removal
    Patent number: 8825348
    Abstract: An exhaust gas purification system including an exhaust gas passageway which routes a flow of exhaust gas from an exhaust gas source to an intake manifold; an exhaust gas passageway valve which controls flow to the intake manifold; a cooling system coupled with the exhaust passageway positioned at a location upstream of the exhaust gas source and downstream of the intake manifold and operable to transfer heat from the flow of exhaust gas to a coolant in flow communication with the cooling system; a bypass passageway coupled with the exhaust gas passageway and bypassing the cooling system; a bypass valve operable to control flow through the bypass passageway; at least one valve operation sensor; and a controller operable to control the bypass valve to direct the flow of exhaust gas to the bypass passageway during exhaust gas recirculation based on a signal from the valve operation sensor.
    Type: Grant

  • Gas extractor for an engine coolant system
    Patent number: 7681537
    Abstract: A system and method for removing gases from an engine coolant system. In one embodiment, the system includes a fluid system that is operable to collects gas, and a gas collection system coupled to the fluid system. The system also includes a venturi pump system coupled to the fluid system and to the collection system, where the venturi pump system is operable to extract the gas from the fluid system via the collection system.
