Beschreibung
Zusammenfassung:	The invention discloses a variable valve actuating mechanism of an engine. The mechanism can realize valve timing and valve stroke changing along with the engine speed and load and mainly comprises anengine cylinder head, an electromagnet, a permanent magnet, a valve spring retainer, a buffer block, a regulating cam, a regulating cam bearer, a valve spring, a valve, a valve guide and a shell body. Break-make of the electromagnet is controlled by an electric control system to realize open and close of the valve by utilizing the theory that homogeneity repulses between the electromagnet and thepermanent magnet. The invention simplifies engine structure and improves reliability of engine working process; open and close moment of the valve and valve stroke are continuous and adjustable, thuscausing performance and potential of the engine to be fully played under all work conditions; no throttle body is needed, thus effectively reducing intake resistance, pumping loss and specific fuel consumption.
