In an embodiment of an exhaust gas purification apparatus, when an accumulation amount of particulate matter in a DPF () exceeds a predetermined amount and an exhaust gas temperature of an engine is lower than a restoration operable temperature, an intake air amount reducing operation is executed by an air intake throttling device () provided for an air intake pipe () of the engine, and a heating operation is executed by an electric heater () provided upstream from the DPF (), thereby increasing the exhaust gas temperature to the restoration operable temperature to start a restoration operation of the DPF ().

Exhaust gas purification apparatus, internal combustion engine comprising the same, and particulate filter restoring method

An exhaust gas recirculation control device in a diesel engine, capable of suppressing NOx and smoke discharged. A first temperature sensor () is provided at a portion more on the upstream side than a portion where a suction air path () joins an exhaust gas recirculation path (), and a second temperature sensor () is provided on the downstream side. Further, an engine load detection sensor () and an engine speed detection sensor () are arranged. The exhaust gas recirculation control device also has memory means where the temperature of suction air before it is mixed with an exhaust gas and a temperature value at a second temperature sensor installation position are previously memorized, the temperature value corresponding to an appropriate exhaust gas recirculation amount that is uniquely defined by an engine load and an engine speed. Further, judging means is provided. The judging means compares the corresponding temperature value memorized in the memory means and a value detected by the second temperature sensor. When the detected value is within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be appropriate, and when the detected value is not within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be abnormal.

Pesticidal composition and method for controlling pests

Benzoylpyridine derivative or its salt, fungicide containing it as an active ingredient, its production process and intermediate for producing it

An object of the present invention is to restrict a part of intake flow which is apt to flow in a direction opposite to a counter swirl flow after colliding against a valve stem, and to produce an intense swirl while controlling a worsening of flow coefficient. A valve seat supporting annular stepped surface( ) is formed on an intake port outlet portion of a cylinder head ( ), its inner peripheral edge is formed into a shape having an inner peripheral edge ( ) of a valve stem ( )for serving as a base circle, and a extending portion ( ) projecting toward a side of a valve stem ( ) is provided on a radial intake port inlet side portion. The extending portion ( ) is formed into a mountain-like shape which widens from a top portion projecting toward the valve stem side to both peripheral sides and connects to the base circle at its foot ends; or into an arc-like shape; or into a trapezoidal shape. A back wall ( ) is formed on a side opposite to the valve seat of the extending portion ( ), the back wall decreasing its projecting height toward an upstream side in the intake port to smoothly connect to an inner peripheral wall surface of the intake port
