    摘要: An ECU opens/closes an EGR valve (43) at a predetermined time (PI) to start blockage detection of an exhaust gas recirculation passage, increases an opening degree of a throttle valve (25) after start of the blockage detection over an opening degree immediately before the start of the blockage detection, and detects a blocking amount of the exhaust gas recirculation passage based on a change amount (ΔGN) in an internal pressure detected by a pressure sensor, which is a difference between the internal pressure detected when the EGR valve is opened and the internal pressure detected when the EGR valve is closed.

    摘要: An engine includes an exhaust gas recirculation circuit, an air throttle system, and a charging system. A method to control the engine includes determining a feed forward control command for a first selected one of the exhaust gas recirculation system, the air throttle system, and the charging system based on an inverse flow model of the first selected system. This includes monitoring a first input based upon an effective flow area of the first selected system, monitoring a second input based upon a pressure value within the first selected system, and determining the feed forward control command for the first selected system based upon the first input and the second input. The first selected system is controlled based upon the feed forward control command for the first selected system.

    摘要: Various methods and systems are provided for controlling exhaust gas recirculation in an engine. One embodiment for a system comprises an engine having first and second cylinder groups, and an exhaust gas recirculation (EGR) passage coupled between the first cylinder group and an intake manifold of the engine, flow of EGR through the EGR passage controlled by one or more EGR exhaust valves, and a controller configured to maintain a target intake gas concentration by adjusting the one or more EGR exhaust valves and adjusting fuel injection amounts to the first cylinder group differently than the second cylinder group.

    摘要: A method and system for increasing regenerative energy available during deceleration by reducing engine pumping losses. The method includes a controller that reduces fuel delivery to the engine and closes an engine throttle during deceleration. The controller identifies the maximum kinetic energy available during deceleration and opens an exhaust gas recirculation (EGR) valve and engine throttle as necessary to reduce a vacuum in an engine intake manifold, thus minimizing engine pumping losses and increasing regenerative energy available during deceleration while ensuring that a catalyst temperature is above a catalyst temperature threshold.
