摘要： PURPOSE:To eliminate exhausted fine particles collected in a filter through effective burning thereof by making exhaust gas to flow through either one of branch exhaust pipes, and heating the filter with a burner provided on the other side of the branch exhaust pipe, in regeneration of a filter. CONSTITUTION:Fine particles in exhaust gas are collected from the full quantity of exhaust gas flowing through filter member 8 by opening the first exhaust pipe 7a by a controller 13 through switching valve 9. A part of exhaust gas is made to recirculate in a suction pipe 3a through EGR pipe 1 and EGR valve 12. On the other hand, when a travel distance and/or a fuel consumption detected with a sensor 17 come to the specified values. Burning is set with a burner 10 facing the first exhaust pipe 7a as well as the second exhaust pipe 7b is opened. Thereby, the filter member 3a can efficiently be heated by the burner 10 at a state where the exhaust gas of low temperature not flowing through the filter member 8, to eliminate fine particles on the filter member 8 by burning.

摘要： PURPOSE:To enhance the exhaust gas purifying performance of a carbon particle capturing means provided in the exhaust system of an internal combustion engine, by adding a carbon combusting means to the carbon particle capturing means for preventing clogging of the same. CONSTITUTION:Between exhaust pipes C and E, there is interposed a carbon particle capturing container 1 which incroporates therein a gaspermeable, heat- resisting member 4 made of wire nettings or the like. On the front side of the container 1, there is provided a purifying means 6 for burning carbon, which has a hollow space therein and supplied with fuel from a fuel pump 21. Further, the purifying emans 6 comprises an ignition plug 14 and a throttle valve (not shown) for controlling the amount of air supplied under pressure from an air pump 13 by means of a motor 10. Here, operation of the pumps 13, 21 ignition plug 14 and motor 10 is controlled by an operation controlling circuit 25 to which is afforded an output signal of a means 26 for detecting a signal relating to the amount of carbon particles of an engine B captured by the carbon particle capturing means.

摘要： PURPOSE:To prevent by-passing of exhaust gas through catalyst converter, by fitting seal plates at opposite openings of a hollow space formed between monolithic catalyst and its container, and press fitting ceramic fibers into the hollow space. CONSTITUTION:Annular metal seal plates 6a, 6b are disposed around the end face of monolithic catalyst 1 in the manner keeping contact with the same, and fabrics 7a, 7b of fine metal wires shaped in an annular form are press fitted in respective spaces formed between plates 6a, 6b and mating projections 51a, 51b of a holding member, so as to absorb axial vibration of the monolithic catalyst 1. At opposite openings of hollow space 4 formed between outer peripheral surface of monolithic catalyst 1 and inner peripheral surface of container 2, annular compression-shaped elements 8a, 8b made of ceramic fiber of alumina or the like are fitted between seal plates 6a, 6b and opposite end portions of metal net 40. Here, the compression- shaped elements 8a, 8b are urged onto the outer peripheral surface of monolithic catalyst 1 and the inner peripheral surface of container 2, so that leakage of exhaust gas into hollow space 4 can be prevented by the element 8a.
