It is an object of the present invention to provide a black smoke exhaust purification apparatus capable of equalizing temperature of a particulate filter and facilitating maintenance thereof. The black smoke exhaust purification apparatus is arranged in series therein with an oxidation catalyst and a particulate filter wherein an inlet for exhaust gas is disposed between the oxidation catalyst and the particulate filter, and wherein an exhaust gas passage is extended from the inlet portion through the oxidation catalyst so as to be connected to an upstream space of the oxidation catalyst.

Black exhaust purification apparatus for diesel engine

An exhaust gas recirculation device for an engine having a cylinder head with a suction port and an exhaust port, provided with a mechanism for recirculating a portion of exhaust gas to the suction side of the cylinder head, comprises a connection hole is opened through a wall of the cylinder head disposed between the suction port and the exhaust port. The connection hole is bored vertically slantwise. The connection hole at the suction side is opened along the direction of swirls of sucked air. A throttle is disposed in at least either a suction flow passage communicating with the suction port or an exhaust flow passage communicating with the exhaust port so that the opening area of the suction flow passage or the exhaust flow passage can be adjusted by the throttle.
