Abstract

PURPOSE:To prevent a decrease of output of an engine when an electric heater is operated, by providing an injection amount increasing device of fuel in the Diesel engine, which incinerates fine particles in a filter in an exhaust passage by the electric heater, so as to operate said increasing device when the heater is electrified. CONSTITUTION:If a detected pressure by a block detector sensor 10 increases higher than the prescribed set pressure at idling operation of an engine 1, a controller 11 recognizes a filter member 6 to be blocked, and a block signal A is applied to an electrifying device 8 and a correction device 12. Then the electrifying device 8 is turned on to open an electrifying circuit to an electric heater 7, allowing the electric current of a battery 9 to flow in the heater 7, and the heater generates heat to incinerate fine particles of carbon in the filter member 6. While a selector valve 17 of the correction device 12 opens a negative pressure introducing passage 15, and negative pressure by a vacuum pump 16 is introduced into a negative pressure chamber 14b in a diaphragm device 14, rotating a working lever 13 counterclockwise while turning a control lever 4a a little clockwise, thus a little more amount of fuel than the minimum injection is supplied from an injection pump 4.

Generally, the exhaust gas of a diesel engine contains a large amount of particulates such as carbon particulates, and a filter member has conventionally been provided in the exhaust passage to collect the particulates. However, in a diesel engine equipped with such a filter member, when the engine is operated for a long time, a large amount of the above-mentioned particulates accumulate on the filter member, which increases the back pressure of the engine and reduces the output. Conventionally, in order to solve this problem,
As described in Japanese Patent No. 7-8311, there is a device in which carbon particles trapped in a particulate filter are incinerated with an electric heater. However, automobiles equipped with this conventional device have problems in that the driving feeling is not smooth and jerky, and furthermore, the engine stalls easily.
