Valve stopping device for internal combustion engine
Abstract:
Disclosed is a valve stopping device for an internal combustion engine that does not allow valves for all cylinders to stop in the closed state even in the event of a failure.The valve stopping device includes a control device 2 and a plurality of actuators 4A, 4B, 4C, 4D, which stop either an intake valve or an exhaust valve. The actuators 4A, 4D for some of a plurality of cylinders included in the internal combustion engine stop a valve in the closed state when energized. The actuators 4B, 4C for the remaining cylinders stop a valve in the closed state when energized. The control device 2 provides control on an individual actuator basis to determine whether or not to energize the actuators 4A, 4B, 4C, 4D.
