EXHAUST GAS PARTICULATE PURIFICATION DEVICE OF DIESEL ENGINE

摘要

PURPOSE:To complete combustion of particulates with a small power consumption by providing a transmitting means which outputs high frequency wave with a minimum output required for combustion of the particulates based on the exhaust gas temperature. CONSTITUTION:An exhaust gas particulate purification device 11 of a Diesel engine 1 has a filter 17 which captures particulates in exhaust gas and a transmitting means made up of a magnetron transmitter 15 which combusts the particulates and reactivates the filter 17 and a waveguide 16. A control means 13 calculates an output value of the magnetron transmitter 15 when the required heating to the particulates as a combustion starting temperature is minimum based on the temperature of the exhaust gas detected by a temperature sensor 25. It is thus possible to combust the particulates efficiently with a small power consumption, and thereby possible to complete the combustion of the particulates with a smaller power consumption.
