Abstract

PURPOSE: To accomplish optimal combustion by providing a hole of an appropriate size in a change-over valve in an apparatus in two trapper are disposed on both sides thereof and fine particles captured by one trapper closed by a change-over valve is removed by combustion.
CONSTITUTION: During ondinary operation of a vehicle, a change-over valve 16 occupies the first position or the second position for passing exhaust gas to either of two trappers 14a or 14b which are disposed side by side to each other. In this state, fine particles contained in exhaust gas are captured by one trapper 14a or 14b through which exhaust gas is passed. When the time of vehicle operation reaches a certain length and the fine particle capturing capacity of said one trapper is saturated, the change-over valve 16 is shifted to the other trapper 14b or 14a by a handle 20 which is driven by a driving means (not shown), and current is supplied to a heater 22a or 22b disposed in the closed trapper 14a or 14b. At the same time, a controlled amount of gas is supplied from a hole 30 formed in the valve 16 for combusting and removing the captured fine particles.
