The purpose of this utility model is that a kind of improved renewable diesel machine filter cigarette apparatus will be provided, it can burn into carbon dioxide and water vapour with the carbon distribution things such as smoke particle that are deposited on soot filter channel, make it reach the effect of regeneration, and can keep the filter runner unimpeded, increase substantially filtering effect, and need not disassembly, cleaning separately, can prolong the smoke filter life-span.

Model utility is achieved in that at smoke filter front end place and is installed with a heat generator, front end place at heat generator is provided with a blower, heat generator is to be made of cell body and one group of ceramic heater, offer inlet hole and one group of ceramic heater fixed hole on cell body respectively, the hole count of inlet hole is identical with the quantity of smoke filter.

The ceramic heater of its heat generator of the utility model mat can produce the high temperature more than 200 ℃, make and be coated on catalytic substance that filter core avoids under this high temperature, can excite and smoke particle equivalance carbonizable substance is burnt into carbon dioxide and water vapour, reach the effect of its regeneration, and the carbon dioxide that the smoke particle equivalance carbonizable substance after the burning forms can be by filter core passage smoothness, need not disassembly, cleaning separately, thereby prolong the working life of smoke filter.
