    摘要： The invention relates to an exhaust gas cooling device (1) for a large internal combustion engine and an internal combustion engine. The exhaust gas cooling device (1) comprises a precooling jet tube (2), an outflow tube (3) and an absorber unit (4), The absorber unit (4) has a height (h), a maximal width (w) and a maximal length (l), wherein the maximal length (l) is longer than the maximal width (w). The exhaust gas cooling device (1) further comprises an inflow deflector housing (6) tapering along the length (l) of the absorber unit (4) and fluidly connected with the precooling jet tube (2) and the absorber unit (4), and an outflow deflector housing (7) tapering along the length (l) of the absorber unit and fluidly connected with the absorber unit (4) and with the outflow tube (3).

    摘要： An internal combustion engine assembly (1) is provided with a fuel tank (4) for fuel comprising ethanol, and a reformer (14b) for steam reforming of ethanol that is with an outlet (37,40) connected to a buffer tank (42).
    A first reformer supply duct (24,22,36) extends from the fuel tank (4) to the reformer (14b) via a fuel evaporator (19a) that is in heat exchanging contact with the exhaust gases, for supplying ethanol vapor to the reformer (14b). A second reformer supply duct (30,33,36) extends from a water reservoir (25) to the reformer (14b) via a water evaporator (17) that is in heat exchanging contact with the exhaust gases.
    The reformer (14b) is in heat exchanging contact with the catalytic converter (14a) and is adapted for reforming ethanol and water into syngas comprising carbon monoxide and hydrogen, and for supplying the syngas via the outlet (37,40) to the buffer tank (42). The reformer (14b) and the catalytic converter (14a) may form an integrated unit (14).

    摘要： A fuel reforming operation in a fuel reformation cylinder (2) is not executed and a warming operation for raising the temperature of the fuel reformation cylinder (2) is executed, when a gas temperature of the fuel reformation chamber (23) at a time point when a piston (22) in the fuel reformation cylinder (2) reaches a compression top dead point is estimated to fall short of a reforming operation allowable lower limit gas temperature. For example, EGR gas is introduced to the fuel reformation chamber (23) without cooling the EGR gas. Further, during a predetermined period from the expansion stroke to an exhaust stroke of the output cylinder (3), an exhaust gas warming fuel is supplied to the combustion chamber (33). Further, the fuel is combusted in the fuel reformation chamber (23)

    摘要： A supercharged internal combustion engine according to the present invention includes: a compressor arranged in an intake passage through which air that is taken into a combustion chamber flows and for supercharging intake air; an EGR passage that connects an exhaust passage through which exhaust gas that is discharged from the combustion chamber flows and a compressor upstream passage; an EGR valve for opening and closing the EGR passage; an intake bypass passage for releasing gas that has been supercharged by the compressor outside a compressor downstream passage; and an ABV for opening the intake bypass passage by opening when the gas that has been supercharged by the compressor is released outside the compressor downstream passage. The intake bypass passage connects the compressor downstream passage with the EGR passage on the side that is closer to the compressor upstream passage relative to the EGR valve.
