Filed: 1999-12-31
Abstract: PURPOSE: A device and a method for eliminating smoke particles are provided to reduce the exhaust gas generated in the initial state of engine operation and to prevent the life of a muffler from being deteriorated by the deposit of the smoke particles. CONSTITUTION: By driving an engine(12), a sensor detects the operation of an engine for increasing the amount of fuel and the mixture of an injection pump. Thus, the idle RPM(Revolutions Per Minute) of the engine is increased. An electronic valve(51) is operated for opening a branch pipe(15) by the operation of an opening and closing member. The electronic valve is operated to close an exhaust pipe(14) by an opening and closing member. Herein, the opening and closing members are operated by the pressure of a fluid tank(52) operating actuators(26,27). Initial exhaust gas from the engine passes through a muffler(16) for passing through a filter(20) by the branch pipe. Thus, smoke particles are collected for being discharged. In the normal operation of the engine, the electronic valve is operated to close the branch pipe while opening the exhaust pipe.
