Abstract

The invention discloses a two-in-one mechanism of continuous variable valve stroke and valve timing of an automobile engine. The mechanism is composed of a rocker arm component, a driving component, a valve component and the like. The rocker arm component comprises a sliding rocker arm, an adjusting rocker arm, a support, a support idler wheel and a reset spring. The driving component comprises a stepping motor, a gear and an adjusting crankshaft. The stepping motor is controlled by an engine computer board, and the stepping motor drives the adjusting crankshaft to achieve continuous variable control over the valve stroke and the valve timing of the engine. The two-in-one mechanism can simultaneously finish two functions of the continuous variable valve stroke and the valve timing, air suction and air exhausting conditions of the engine are improved effectively, air suction and air exhausting resistance is reduced, power consumption of the engine is further reduced, and the good effects of outputting power, reducing oil consumption and reducing emission of the engine are fully played. The two-in-one mechanism of the continuous variable valve stroke and the valve timing of the automobile engine is compact and simple in structure, low in cost, high in efficiency and long in service life, and can be applied to an air suction and air exhausting system of automobile engines with various types.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and relates to a continuously variable valve lift mechanism of an automobile engine. Background technique [0002] In order to improve the power performance, fuel economy and emission indicators of automobile engines, staged variable valve lift and continuously variable valve lift technologies are adopted on automobile engines. Judging from the current automobile market, there are not many manufacturers with continuously variable valve lift technology for automobile engines, and their continuously variable valve lift mechanisms generally function as the valve lift increases. , The advance angle and retard angle of the exhaust all increase at the same angle, and there is a defect that the advance angle and retard angle of the intake and exhaust fail to change correspondingly with the change of the engine's operating conditions, so their continuously variable valves The lift mechani...
