Valve driving apparatus provided in an internal combustion engine |
摘要 |
A valve driving apparatus for driving an exhaust valve, using electromagnetic force provided in an internal combustion engine, the exhaust valve being movable between an open position and a closed position. An armature is coupled with the exhaust valve. An em coil generates an em force exerted on the armature. A valve spring generates a force exerted on the exhaust valve. A controller changes a normal state of movement of the exhaust valve to a state of movement that prevents the armature from bouncing off the em coil at the open position when combustion is suspended in the internal combustion engine.
