摘要： A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes a first upstream passage into which the EGR gas cooled by an EGR cooler flows, a second upstream passage into which the EGR gas that bypasses the EGR cooler flows, a junction connected to each of a gas-flow downstream side of the first upstream passage and a gas-flow downstream side of the second upstream passage, and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body opens and closes the second upstream passage. The EGR valve body is provided in the downstream passage, rotates around an EGR valve axis.

摘要： A coolant collector bracket including a front side, a back side, and a top side is provided. The back side is opposite the front side and includes a plurality of coolant inlets for receiving coolant from a cylinder head. The top side includes an exhaust gas recirculation (EGR) cooler inlet and an EGR coolant outlet. The EGR coolant inlet and the EGR coolant outlet are substantially orthogonal to the plurality of coolant inlets.

摘要： A method to control the combustion of an internal combustion engine comprising determining a combustion model providing a spark advance value depending on an objective value of a quantity representing the incidence of a low-pressure EGR circuit, of the rotation speed, of the intake efficiency and of an open-loop contribution of a combustion index; calculating a first closed-loop contribution of the spark advance depending on the combustion index; calculating a second closed-loop contribution of the spark advance depending on a quantity indicating the knocking energy; and calculating the objective value of the spark advance angle to be operated through the sum of the spark advance value provided by the combustion model and of the first closed-loop contribution or, alternatively, of the second closed-loop contribution.

摘要： An engine system includes an engine with a combustion chamber, an intake line in which external air flows, and an exhaust line in which exhaust gas flows. A compressor is disposed in the intake line and rotated with a turbine to compress external air. A first recirculation line is branched off from the exhaust line and merged into the intake line. An EGR cooler cools exhaust gas flowing through the first recirculation line. A second recirculation line is branched off from the first recirculation line. A bypass line is branched off from the first recirculation line between an electric supercharger and the EGR cooler. A three-way valve is disposed where the bypass and first recirculation lines join. An intake valve is disposed in the intake line between where the first recirculation line and intake valve join and where the bypass line and intake valve join.

摘要： An object of the present invention is to predict change of a combustion limit due to cycle variation of temperature and an EGR ratio and perform correction every cycle to decrease an amount of combustion consumption. Therefore, in an internal combustion engine control device that controls an internal combustion engine including a cylinder and an exhaust pipe, the internal combustion engine control device includes a control unit configured to perform EGR control of controlling an exhaust gas in the exhaust pipe to return to an inner cylinder of the cylinder, obtain temperature of the gas in the internal cylinder and an EGR ratio in a state where both an intake valve and an exhaust valve are closed in an combustion cycle, and correct a combustion parameter in a same combustion cycle as the combustion cycle on the basis of the obtained gas temperature and the obtained EGR ratio.
