    摘要： Heat exchangers (H4, H3, H2, H1) disposed in an exhaust port (18) provided in the exhaust passage (33) of an internal combustion engine, in the pre-catalytic device (34) thereof, and on the downstream side of the main catalytic device (35) thereof, respectively, wherein the density of heat transfer surface (heat transfer surface/volume) of the heat exchanger (H4) on the upstream side of the exhaust passages (33) is minimum and that of the heat exchanger (H1) on the downstream side thereof is maximum among the densities of heat transfer surfaces of all heat exchangers, whereby, because the density of heat transfer surface is reduced on the upstream side of the exhaust gas passages (33) at the portions where the temperature of the exhaust gases is high, and the density of it is increased on the downstream side of the exhaust gas passages (33) at the portions where the temperature of the exhaust gases is low, a uniform heat transfer performance can be assured through the entire area of each of the heat exchangers (H4, H3, H2, H1).

    摘要： An internal combustion engine, wherein the temperature of exhaust gas lowers gradually from the upstream side to the downstream side in the flow direction thereof and the temperature of a working medium for a heat exchanger flowing in the direction reverse to that of the exhaust gas rises gradually from the upstream side to the downstream side in the flow direction thereof, a temperature difference between the exhaust gas temperature and the working medium temperature is minimized in a boundary portion between the liquid phase area and the two-phase area of the working medium, and a catalyst device is positioned near the minimum temperature difference position and assembled on the upstream side in the flow direction of the exhaust gas, whereby a heat generated by the catalyst device can be utilized effectively by the heat exchanger and, since the catalyst device is disposed in the two-phase area of the working medium with a constant temperature and the constant temperature is a catalyst activity temperature, the catalyst device allows the catalyst to develop a stable exhaust gas purification performance.
