Embodiment 1

[0030] Embodiment 1 of the present invention provides a gas distribution mechanism for an engine, including a camshaft, a transmission mechanism and a valve, wherein the cam on the camshaft and the transmission mechanism or between the transmission member and the transmission member in the transmission mechanism are arranged There is a slide plate, which has a smooth transition profile; the above-mentioned engine valve mechanism also includes a slide plate control device, which is connected with the slide plate, and is used to control the position of the slide plate between the cam and the transmission mechanism or the position of the slide plate in the transmission The position between the part and the transmission part, and the distance of the transmission mechanism can be changed through the smooth transition of the slide.

[0031] This embodiment is explained by setting a sliding plate between the cam and the transmission mechanism as an example, taking the cam driving the ...

Embodiment 2

[0036] Figure 1-Figure 4 Both are partial structural schematic diagrams of the engine valve train provided by Embodiment 2 of the present invention, wherein figure 1 Shown is the valve closed state of the engine valve train under one valve lift, figure 2 Shown is the valve fully open state of the engine valve train under one valve lift, image 3 Shown is the valve closed state of the engine valve train under another valve lift, Figure 4 Shown is the fully open state of the valve mechanism of the engine under another valve lift. Embodiment 2 of the present invention provides an engine valve mechanism, which is based on Embodiment 1, and further provides a preferred solution, wherein the part between the sliding plate 3 protruding from the cam and the transmission mechanism 2 is formed with a sliding plate body 5 The side of the slide body 5 away from the camshaft 1 is provided with an accommodation groove; the slide control device also includes a movable block 6, which is...

Abstract

The invention provides a valve timing mechanism for an engine, the engine and an automobile. The engine comprises a cam shaft, a transmission mechanism and a valve, wherein a sliding sheet is added in the transmission mechanism, a molded line for smooth transition is arranged on the sliding sheet, the valve timing mechanism further comprises a sliding sheet control device connected with the sliding sheet and used for control the position of the sliding sheet between a cam and the transmission mechanism, and the distance between the cam and the transmission mechanism is changed through the molded line of the sliding sheet for smooth transition. The valve timing mechanism for the engine, the engine and the automobile achieve change of valve stroke and the molded line by arranging the sliding sheet between the cam shaft and the transmission mechanism, appropriate valve strokes and molded lines are selected according to different working conditions of the engine, and dynamic property and economical efficiency of the engine are improved.

Description

technical field [0001] The invention relates to the structural technology of an automobile engine, in particular to an engine gas distribution mechanism, an engine and an automobile. Background technique [0002] The engine is a very important part of the car, and the engine is equipped with a valve train to control the intake and exhaust of the engine. The gas distribution mechanism generally includes a camshaft, a tappet, a rocker arm and a valve. The camshaft with a certain profile drives the tappet or the rocker arm according to a certain timing relationship, thereby driving the intake and exhaust valves to open according to a certain profile and timing. close. Here, the tappet, rocker arm, etc. that transmit the control action of the camshaft to the valve are called the transmission mechanism between the camshaft and the valve. [0003] The valve lift and sporty line can directly affect the effect of intake and exhaust, thereby affecting the economy, power and emissio...
