Anti-corrosion device of exhaust system for automobile

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrosion protection device for an automobile exhaust system, wherein the exhaust gas outlet of the tail pipe leading from the main muffler can be selectively opened and closed by a predetermined operating means according to on / off of the starter. By installing a tailpipe cap, the tailpipe cap automatically closes the exhaust outlet when the engine is turned off, thereby preventing oxygen from entering, thereby preventing the oxygen from condensing with the condensate inside the exhaust system. An object of the present invention is to provide a corrosion protection device for an automotive exhaust system that can prevent internal corrosion of the corrosive metal parts constituting the system.
