Further, in order to improve the output of the engine, the vehicle is pressurized by a supercharger and heated. It is known to provide an intercooler that cools the temperature of the intake air to increase the intake air density.

機械負荷を軽減でき、エンジンの耐久性を向上できる。[0003] There are two types of intercoolers, a water-cooled type and an air-cooled type. As shown in Fig. 3, both are provided in an intake passage 2 connecting a supercharger 8 and an intake manifold 4, and cool the air A whose temperature has risen. Then, by lowering the temperature of the air A entering the combustion chamber and improving the air charging efficiency, the air amount can be increased and the fuel efficiency can be increased, so that the combustion can be improved and the fuel efficiency can be improved. Further, since the maximum temperature and the maximum pressure can be reduced, the heat load and the mechanical load of the engine can be reduced, and the durability of the engine can be improved.

る。On the other hand, in order to reduce the amount of NOx emitted from the exhaust gas of the engine, an EGR (exhaust gas recirculation) is used in which a part of the exhaust gas is recirculated into the intake air to suppress the combustion temperature and suppress the generation of NOx. ) Is effective, widely used,
The exhaust manifold 5 and the intake passage 2 are connected by the EGR passage 1, and a part of the exhaust gas Ge is recirculated to the engine E.

る。When the EGR rate is increased, the amount of air in the amount of intake gas entering the cylinder decreases, so that the amount of oxygen in the intake gas decreases and combustion deteriorates, leading to an increase in the amount of smoke generated. Therefore, an EGR cooler 6, which is a water-cooled or air-cooled heat exchanger, is disposed in the EGR passage 1 to cool the EGR gas Ge, thereby improving the air intake efficiency with an increase in the density of the EGR gas. In addition to realizing a stable combustion state, the effect of reducing NOx is increased by lowering the combustion temperature due to the lowering of the EGR gas temperature.
