The aims of research of this paper are as follows; first of all, main contents of technical development are such as. 1. the burner system development for maximum efficiency of diesel particulate filter in low temperature emission gas, 2. the development of white fume reducing system by the second ejection in diesel, 3. the development of burner system for erasing of oxidation catalyzer of the most important role in diesel particulate filter, And the secondhand, expectation effect of this paper is such as. If the mass production of this development is successfully, this system is easy to applicable to small diesel vehicle stopping by low efficiency diesel particulate filter and is increased cost effective and adaptability by erasing oxidation catalyzer.
