摘要： An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.
摘要翻译：排气后处理系统包括用于将尿素水喷射到排气管道中的喷射器，以及设置在喷射器相对于废气流的下游的脱硝催化剂。排气后处理系统使用由喷射器注入的尿素水产生的氨，还原脱硝催化剂，还原废气中的氮氧化物。尿素水沿着排气管道内的废气流动的方向喷射，多孔板在排气管道的空间内以多级设置，使得喷射的尿素水的液滴在到达排气管的壁面。受到液滴撞击的多孔板的表面被布置成面向排气相对的下游。当液滴撞击多孔板时，通过使膜沸腾来防止尿素水的沉积，由多孔板反射的尿素水均匀地分散在废气中。因此，尿素水均匀地分散在排气中，而不会增加排气的压力损失。防止尿素水沉积在壁表面上并产生固体形式的沉淀。

摘要： Atomization and vaporization of spray in a fuel supply system is promoted at the time of cold startup and the amount of fuel depositing on the inner wall of the intake manifold is reduced, thereby ensuring improved startability of an internal combustion engine of a car, reduced fuel costs and improved purification of exhaust gas. A very fine groove is formed on a heat transfer surface in a fuel vaporization promoting apparatus, wherein this groove is shaped in such a way that fuel is dispersed by the surface tension of the heat transfer surface and the fuel. This configuration ensures uniform dispersion of fuel on the heat transfer surface and effective promotion of vaporization.
