Abstract
A particulate trap for use in a diesel engine can efficiently trap particulates contained in exhaust gas with low pressure drop and can burn collected particulates for regeneration with less power consumption. A filter element having a built-in electric heater is mounted in a case provided in the exhaust line of a diesel engine. The filter has two mutually opposed surfaces between which is mounted the electric heater. With this arrangement, it is possible to increase the filtration area and also the heating efficiency.
