VARIABLE VALVE DRIVING MECHANISM OF ENGINE, AND ENGINE

A variable valve driving mechanism of an engine, and the engine. The variable valve driving mechanism comprises a rocker arm (1) configured to control open and close of a valve (7) and a servo rocker arm (2) arranged in parallel to the rocker arm (1). A swing end of the servo rocker arm (2) extends to the top of the swing end of the rocker arm (1). A valve adjustment gap (1-2) provided in the swing direction of the servo rocker arm (2) and the rocker arm (1) is formed between the servo rocker arm (2) and the rocker arm (1). A gap compensating device telescopically filling the valve adjustment gap (1-2) and configured to adjust the valve (7) to be delayed to close or open in advance when extending to the valve adjustment gap (1-2) is provided between the servo rocker arm (2) and the rocker arm (1). When the valve (7) is open or closed normally, the gap compensating device is contracted, and the rocker arm (1) is not in contact with the servo rocker arm (2) in the swing process by means of the valve adjustment gap (1-2). When it is required to control the valve (7) to be delayed to close or open in advance, the gap compensating device extends into the valve adjustment gap (1-2) to eliminate the gap, and the open/close time of the valve (7) is adjusted to avoid the problem that the valve is not properly closed caused by a plurality of oil control paths.
