Abstract

PURPOSE:To prevent a catalyst device from corrosion by providing a means to change the overlapping period of suction and exhaust valves, a means to detect an engine speed and control means to control these changing means. CONSTITUTION:An exhaust turbosupercharger 11 driven by the energy of exhaust gas and supercharging intake gas and a catalyst device 12 purifying exhaust gas are provided. A means 60 for changing the overlapping period of suction and exhaust valves 5 and 9 and means 23 for detecting engine speed are provided. A means 70 for controlling the means 60 is provided so that in the higher speed range an engine is operated, the overlapping period may become shorten. This can improve the responsibility of an exhaust turbosupercharger preventing the catalyst device corrosion.
