Abstract: When the operating state of an internal combustion engine (10) is under low load, the supply of unburned fuel is controlled by using post-injection without using in-exhaust-pipe direct injection. Under medium load, the supply of the unburned fuel is controlled by using both the post-injection and the in-exhaust-pipe direct injection. Under high load, the supply of the unburned fuel is controlled by using the in-exhaust-pipe direct injection without using the post-injection. Thus, in air-fuel ratio rich control performed during regeneration to recover the purification capability of an exhaust gas purification apparatus, both black smoke and white smoke are reduced when the supply of the unburned fuel for supplying the unburned fuel into exhaust gas is controlled.

Abstract: A cam shaft reduces noise produced by gears used to drive cams of a fuel injection pump. Conventionally, the gear noises are caused by negative torque of a cam shaft. A cam profile of each cam which lifts a plunger of the fuel injection pump is shaped like a fan. There are formed two cams in a single cam shaft. A lift increment segment of a first cam overlaps a lift decrement segment of a second cam to prevent a negative torque.

Abstract: An exhaust gas purifier including an NOx catalyst of the selective reduction type and a diesel particulate filter arranged in series, and being disposed in an exhaust passage of an internal combustion engine. The purifier includes a passage for urea supply having a hydrolysis catalyst therein and a passage for hydrocarbon supply having an oxidation catalyst therein. The passages are parallel to each other and separate on an upstream side of both the NOx catalyst and the diesel particulate filter. A urea feeder which supplies urea to the passage for urea supply and a hydrocarbon feeder supplies hydrocarbon to the passage for hydrocarbon supply. The injection of an urea is thereby reconciled with the direction injection of hydrocarbon into the exhaust pipe in a compact space.

Abstract: In this piston, oil grooves 5 are provided in the selected parts of a surface of a skirt portion 3 which are liable to encounter the breakage of an oil film, and which are on the thrust side and anti-thrust side, and not in the parts of the surface of the skirt portion to which a load is imparted. The oil grooves 5 are formed in the positions higher than a piston pin 22 and lower than piston ring grooves 12, and cooling cavity 45 and oil grooves 5 communicate with each other by oil passages 47, the cooling cavity 45 and a lower open end 48 of a piston body 1 communicating with each other by an oil passage 46. Accordingly, even when the piston is inclined toward the anti-thrust direction, an oil is supplied to the clearances between outer members 7 and skirt portion 3, and the breakage of an oil film does not occur. Even when the piston body is inclined toward the thrust side and going to collide with the outer members 7, a satisfactory oil film is formed securely in the portion of the clearance which is around the colliding portion of the piston body, and the oil in the clearance is forced out. Thus, the colliding force of the piston against a cylinder liner is lessened by the oil, so that the slapping sounds of the piston can be greatly reduced.
