Abstract：
 The exhaust particle trap for diesel truck as one vehicle tail gas purifying device consists of electrically regenerating heater, catalytic oxidizing device, and composite metal-base netted plate coated with regenerating catalyst inside the cylindrical casing between the front and the back conic tubes. Inside the cylindrical casing, the heater raises the temperature of the exhausted gas, the catalytic oxidizing device oxidizes HC and CO for purification, the multiple composite netted plate captures the exhaust particles, and coated regenerating catalyst lowers the burning point of carbon smoke, makes most carbon smoke burnt out under the tail gas temperature and prevents it to enter to atmosphere while burning out the trapped particles. The product of the present invention, when installed to diesel truck, has good passage performance, very low exhaust back pressure loss and no obvious influence on the power performance.
