ELECTRIC DISCHARGE EXHAUST GAS CLEANING DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To obtain excellent cleaning performance even in the case that an exhaust gas temperature at a start operation time is low by using a short pulse high repetition switch element contrived a long service life. SOLUTION: In an electric discharge exhaust gas cleaning device of an internal combustion engine by which an electric source power is fed to a corona discharge tube 23 via a short pulse high repetition switching element to generate a corona and a harmful component contained in the exhaust gas of the internal combustion engine 26 is removed, the short pulse high repetition switching element is made to an MAGT 24.
