Title:
EXHAUST REPURIFIER OF DIESEL ENGINE
Document Type and Number:
Japanese Patent JPS60128920
Kind Code:
A
Abstract:
PURPOSE:To reduce the sizes of an electric heater and a battery by accumulating thermal energy generated by the heater, in a heat accumulator in advance and heating regenerated gas by accumulated energy so as to heat a collecting member provided with catalizer when said member is repurified. CONSTITUTION:Particulates involved in exhaust gas fed from an engine 1 are collected by a collecting member 4 and a clogged amount detector 24 which detects variation in electric resistance between electrodes 25 and 25 discriminates that the quantity of collected particulates reaches a specified value. If the detector discriminates the member is clogged, an electric heater 13 is electrified and heated to heat a heater accumulating member 14 so as to accumulate heat energy. It is discriminated whether the temperature of heat accumulating member detected by a temperature detector 23 reaches a specified value or not and if an air pump 6 is actuated on the basis of the discrimination of YES. The first and second opening and closing valve 9 and 10 are closed and the third opening and closing valve 11 is opened. And high temperature regenerated gas (or air) is produced in the heat accumulating member 14 and sent to the collecting member 4 so as to heat and burn particulate composition.
