Abstract

The invention discloses a vehicle, an engine and a variable valve lift device of the vehicle. The variable valve lift device comprises a valve mechanism, a cam shaft mechanism, a swing arm mechanism and an adjusting mechanism, wherein a roller rocker arm is arranged at the top of the valve mechanism, the cam shaft mechanism is arranged above the valve mechanism, the swing arm mechanism is disposed between the roller rocker arm and the cam shaft mechanism, and a cam drives the swing arm mechanism to swing around the swing arm rotation axis of the swing arm mechanism. The adjusting mechanism comprises an adjusting shaft and a drive assembly, wherein an eccentric wheel is sleeved outside the adjusting shaft eccentrically, and the drive assembly is used for driving the adjusting shaft to rotate around the central axis of the adjusting shaft, so that the eccentric wheel drives the swing arm mechanism to rotate around the adjusting rotation axis of the swing arm mechanism. The variable valve lift device is capable of adjusting a valve lift continuously and changeably, simple in structure and high in stability.

Description

technical field [0001] The invention relates to the field of automobile construction, in particular to a variable valve lift device for an engine, an engine including the same, and a vehicle including the engine. Background technique [0002] As environmental problems and energy problems become more and more serious, internal combustion 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] Traditional gasoline engines adjust the size of the air intake by changing the throttle to make the engine output different power and torque. Under light load conditions, the throttle opening is small, the engine air intake...
