<p>PURPOSE:To prevent the formation of a large temp. difference at a trap part by firing collected fine particles after the warmth of the trap is confirmed. CONSTITUTION:The opening of a suction throttle valve 12, the pressure on the suction side of a Diesel engine 10, the water temp. of the engine, and the load of the engine are detected respectively by an opening sensor 52, a pressure sensor 54, a temp. sensor 56, and a load sensor 58. And the collected fine particles are fired after the warmth of a trap 20 is confirmed. In this way, the formation of a large temp. difference at the trap part 20 can be prevented, and the damage and failure of the trap is avoided. Accordingly the depend ability on the apparatus is increased.</p> |
