Abstract: An internal combustion engine, a method of operating the internal combustion engine, and a controller are disclosed. The method may comprise measuring a first pressure at a first position in a fluid line containing pressurized fluid; comparing the first pressure to a first threshold; in response to the first pressure exceeding the first threshold, transmitting a signal to depressurize the fluid line; after transmitting the signal to depressurize the fluid line, measuring a second pressure in the fluid line and comparing the second pressure to at least one of a second threshold and a third threshold, the second threshold being greater than the third threshold and less than the first threshold; and in response to the second pressure being less than the second threshold and exceeding the third threshold, transmitting another signal to depressurize the fluid line.

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.
