摘要： A purpose of the present invention is to prevent a PM-caused short circuit between a heating element and a case in an electrically heated catalyst. The electrically heated catalyst is provided in an exhaust gas passage of an internal combustion engine the air-fuel ratio of which is controlled at a ratio near a theoretical air-fuel ratio at an operation time. The electrically heated catalyst includes a heating element that generates heat through electric conduction, a case that stores the heating element therein, and an insulating member sandwiched between the heating element and the case. According to the present invention, the heating element is electrically conducted after the operation of the internal combustion engine is stopped.

摘要： A laminated body composed of a holding member and an inner cylinder is arranged between a heat generation element, which is electrically energized to generate heat, and a case which covers the heat generation element, and the inner cylinder has an upstream side end portion extended to a more upstream side than an upstream side end face of said heat generation element and an upstream side end face of said holding member to form an extension portion, which is formed with a protruding portion protruding to an inner side in a diametrical direction. A flow of an exhaust gas, which flows backwards after colliding with the heat generation element, will be obstructed by said protruding portion. As a result, the backflow exhaust gas stops flowing into a gap between the case and the inner cylinder.

摘要： A spark ignition type internal combustion engine of the present invention comprises a variable closing timing mechanism able to change a closing timing of an intake valve after intake bottom dead center and an EGR mechanism making a part of the exhaust gas flow again into a combustion chamber as EGR gas. The EGR mechanism is controlled so that the amount of EGR gas is reduced when the closing timing of the intake valve is at a retarded side, compared with when it is at an advanced side. Due to this, occurrence of variation among cylinders in the air-fuel ratio and intake resistance along with blowback of intake gas can be suppressed.
