Problems solved by technology

[0011] To sum up, the above variable intake structures have the following technical limitations: (1) Schemes 1-4 cannot continuously adjust the intensity and form of the gas macroscopic movement in the cylinder, and belong to the two-state adjustment scheme, and the structure is generally more complicated (2) Although Scheme 5 can continuously adjust the macroscopic movement of the gas in the cylinder to a certain extent, it only has the function of continuous adjustment for a single movement - eddy current or tumble flow - and cannot implement adjustment for the intensity and composition of the oblique axis vortex movement. Need to adjust

Embodiment Construction

[0021] Such as figure 1 Shown: a variable oblique-axis vortex adjustment mechanism for an engine, which is composed of an oblique-axis vortex control valve shaft 1, an oblique-axis vortex control valve 3, a connection part 4 with the engine cylinder head, and a connection part 6 with the intake manifold; There is a certain angle α between the swirl control valve axis and the horizontal plane or crankshaft axis v-axis . A transition air passage 5 is installed between the part connected to the engine cylinder head and the part connected to the intake manifold. The valve body is respectively connected with the connecting part 4 with the engine cylinder head and the connecting part 6 with the intake manifold through connecting screws 2 .

[0022] This mechanism is used in a multi-valve engine with one-piece air passage, and it needs to be carried out according to the following steps:

[0023] 1. Design as figure 2 The variable inclined axis eddy current test adjustment device...

Abstract

The invention relates an engine variable inclined shaft vortex regulating mechanism, characterized in comprising inclined shaft vortex control valve, inclined shaft vortex control valve shaft, connection part for connecting with engine cylinder cover and connection part for connecting with air inlet multifold. The inclined shaft vortex control valve makes a certain angle alpha v-axis with the axis of the horizontal or a bent shaft. The advantages of the invention: it can continuously regulate the strength and composition of macro movement--inclined shaft vortex movement in the engine, and has characters of simple structure, regulating convenience, being easy to implement, and low cost.

Description

[0001] Field: [0002] The invention relates to a device on an engine, in particular to an engine variable inclined axis vortex adjustment mechanism. Background technique: [0003] The macroscopic movement of gases in the cylinder can be used to improve the combustion process of the engine. In diesel engines, swirl and squeeze motions are usually used to promote fuel atomization and its mixing with air. In gasoline engines, macroscopic movements such as vortex, tumble and squeeze are often used. Their functions include: promoting the formation of mixed gas and increasing the turbulence intensity during combustion. The organic combination of vortex and tumble motion forms an oblique-axis vortex. Its main function is to accelerate the combustion in the early stage, stabilize the ignition process, accelerate the subsequent combustion of the entire charge, and expand the lean burn limit. In addition, the development of stratified lean combustion technology also shows that the ma...
