Problems solved by technology

The butterfly valve is closed at startup and idle conditions, which can effectively improve the combustion conditions under these conditions. In other conditions, such as low-to-medium speed or low-to-medium load, strong tumble motion is also required, but the two working conditions When the butterfly valve is open, the variable tumble does not work

Embodiment 1

[0023] This embodiment relates to an engine continuously variable intake tumble flow control mechanism, which is arranged in the intake duct of the engine, figure 1 As shown, it includes a top plate 1 arranged horizontally in the state shown in the figure, a supporting and blocking device 2 connected to the bottom of the top plate 1, and a power transmission mechanism connected between the supporting and blocking device 2 and the power output device 3. The power is transmitted to the supporting and blocking device 2 through the power transmission mechanism, so that the supporting and blocking device 2 always maintains the horizontal state of the top plate 1 while driving the top plate 1 to have a vertical displacement. In this embodiment, the power output device 3 uses a servo motor.

[0024] Wherein, the supporting and blocking device 2 includes a first side plate 21 and a second side plate 22 of the same size which are arranged in parallel and connected under the top plate 1. Th...

Embodiment 2

[0029] This embodiment relates to an engine, and is an application of the continuously variable intake tumble flow control mechanism of the engine involved in the first embodiment. by figure 2 Combine image 3 As shown, the engine of this embodiment has four intake ducts, and each intake duct is provided with the engine continuously variable intake tumble flow control mechanism involved in the first embodiment. by image 3 As shown, the engine continuously variable intake tumble flow control mechanism is basically the same as the first embodiment, except that four sets of supporting and blocking devices 2 and the top plate 1 are used in conjunction with each other, and they share one rotating shaft 41, one Root driven shaft 42, a power output device 3 and a speed reduction structure.

[0030] by figure 2 As shown, the power output device 3 is fixedly arranged on the main body 6 of the engine, and the rotating shaft 41 connected with the driven gear 44 extends from the outside o...

Abstract

The invention relates to a device for adjusting air flow in an air inlet pipeline of an engine, in particular to a continuous changeable air inlet tumbling flow control mechanism of the engine. The continuous changeable air inlet tumbling flow control mechanism of the engine comprises a top plate, a supporting stopping device and a power transmission mechanism, wherein the supporting stopping device is used for supporting the top plate and carrying out stopping on the air flow in the air inlet pipeline, and the power transmission mechanism is arranged between the supporting stopping device and a power output device in a connected mode. Meanwhile, the invention further relates to the engine with the continuous changeable air inlet tumbling flow control mechanism. According to the technical scheme, the area of an unblocked channel formed above the top plate can be adjusted at any time, and continuous changeable performance of air inlet tumbling flow can be achieved.

Description

technical field [0001] The invention relates to a device for adjusting airflow in an engine intake duct, in particular to an engine continuously variable intake tumble flow control mechanism, and at the same time, the invention also relates to an engine with the control mechanism. Background technique [0002] Direct injection gasoline engine is recognized as one of the important technologies for automobile energy saving and emission reduction. Compared with port injection gasoline engine, it has faster transient response, lower cold start emission, quick start and stop and high thermal efficiency, and can realize stratified combustion. The supercharging technology can further realize the reduction and strengthening of the engine cylinder, so as to achieve the purpose of reducing the weight of the whole vehicle and reducing fuel consumption. Because the oil-air mixing process is carried out in the cylinder, the quality of the oil-air mixing directly affects the success or fa...
