A side feed inlet port for an injector, which makes use of stamped parts to form a compact, high strength three-piece inlet port at a significantly reduced cost. By using an inner sleeve and an outer sleeve, injector sealing is accomplished using the interior sleeve, creating a sealing point, while allowing for inlet conduit attachment to the outer sleeve at, above, or below the sealing point of the DEF injector. The construction of the inlet port is such that there is proper sealing between the inner sleeve and one or more seals, while allowing for the connection between the inlet conduit and the outer sleeve to reduce the overall height of the inlet port, and therefore, the injector. The position of the inlet conduit may be altered without affecting the sealing connection between the inner sleeve and the seal(s), such that the desirable overall height may be achieved.

A vehicle includes an internal combustion engine, an electrically-heated catalyst device provided in an exhaust passage thereof, and an electronic control unit configured to control base material electric power supply supplied to a conductive base material. The catalyst device includes the conductive base material that generates heat upon energization, and a catalyst heated through the conductive base material. The electronic control unit determines whether the conductive base material is in a stagnant period, where temperature of the conductive base material partially stagnates in a prescribed temperature zone, the stagnant period occurring when water is present inside the catalyst device in a process of increase in temperature of the conductive base material. When determining that the conductive base material is in the stagnant period, the electronic control unit controls the base material electric power supply to be lower than when determining otherwise.
