Abstract
A valve stopping device of internal combustion engine comprising, an intake valve and an exhaust valve each provided with a valve stopping mechanism. The valve stopping mechanisms are connected with each other by a link mechanism so as to rotate synchronously. The turning angle of the valve stopping mechanism attached to the intake valve is larger than that of the exhaust valve. The intake valve operation therefore precedes the exhaust valve operation when the valves shut down and enter a closed state. The exhaust valve operation precedes the intake valve operation when the valves begin operation. Thus, burnt gas in cylinders is prevented from being blown back to the intake side during a valve shutdown control process.
