Abstract

The invention relates to a valve driving device and method of an engine. The valve driving device comprises a rocker arm main body, a driving reset part, a wheel part and a valve driving part, and is positioned between a cam shaft and a valve. The wheel center of the wheel part has an initial state position and a set state position relative to the center of the cam shaft, and the switching between the initial state position and the set state position is realized through the driving reset part and the wheel part. The valve driving device generates different valve lifts at the initial state position and the set state position, so that different valve motions are realized. The system is simple and reliable in structure, and the fuel economy of the engine can be improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a valve driving device for an engine brake and a driving method thereof. Background technique [0002] As environmental problems and energy problems become more and more serious, engines, as the main "consumers" of petroleum energy in the world, are the first to receive special attention. Internal combustion engines are currently the most widely used power machinery in the world and cannot be replaced in a short period of time. Therefore, How to make the internal combustion engine cleaner and more economical is the goal pursued by the world's major automobile manufacturers in recent years. [0003] The maximum valve lift of a traditional engine is fixed and invariable during normal operation, that is, there is only one cam profile of the camshaft. This makes it impossible for the lift to make the engine respond well in both high-speed and low-speed areas. The valve lift of the traditiona...
