VALVE SYSTEM CHARACTERISTIC CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a valve system characteristic control device capable of restraining deterioration of combustion. SOLUTION: This valve system characteristic control device is applied to a valve system device 1 furnished with an electromagnetic drive device 17 capable of changing an opening time area of an exhaust valve 16 of an internal combustion engine 2. Additionally, it is furnished with a combustion deterioration judging means 18 to judge combustion deterioration of the internal combustion engine 2 and an exhaust valve drive control means 18 to control the electromagnetic drive device 17 so that the opening time area of the exhaust valve 16 of the internal combustion engine 2 becomes large in the case when the combustion deterioration is judged by the combustion deterioration judging means.
