Throttle valve flashboard, throttle valve main body, throttle valve device and vehicle

Abstract

The invention relates to the technical field of air intake of engines, and discloses a throttle valve flashboard, a throttle valve main body, a throttle valve device and a vehicle. The throttle valve flashboard comprises a flashboard body, the flashboard body is used for being movably arranged on the throttle valve ,main body so as to adjust the communication area of the throttle valve air inlet channel, and a rack extending in the moving direction is arranged on the flashboard body. In actual use, the throttle valve flashboard can be movably inserted into the flashboard opening of the air channel wall of the throttle valve air inlet channel and extends into the throttle valve air inlet channel, the rack is driven by the external gear, and the throttle valve flashboard can move so as to adjust the communication area of the throttle valve air inlet channel. When full opening is needed, the flashboard body can be completely moved out of the air inlet channel of the throttle valve, no obstacle exists in the air inlet channel of the throttle valve, air inlet loss can be avoided, the air inlet amount can be ensured, and therefore an engine can obtain higher power torque, higher heat efficiency and lower emission.

Description

technical field [0001] The invention relates to the technical field of engine air intake, in particular to a throttle gate, a throttle body, a throttle device and a vehicle. Background technique [0002] At present, butterfly valves are used in the throttle valve of vehicles, that is, a butterfly valve that rotates around the butterfly valve shaft is arranged in the intake pipe, and the rotation angle is 0-90 degrees. degree adjustment. [0003] However, this kind of throttle has certain shortcomings. For example, when the throttle is fully open, that is, when the butterfly valve rotates 90 degrees, there will be a loss of intake air, which will lead to insufficient fresh air entering the cylinder, which will affect the fuel atomization, oil and gas. The degree of mixing and the quality of combustion have a certain impact, resulting in a decrease in output power, insufficient torque, and increased emissions; in addition, this kind of throttle valve is more complicated, occu...

[0003] However, this kind of throttle has certain shortcomings. For example, when the throttle is fully open, that is, when the butterfly valve rotates 90 degrees, there will be a loss of intake air, which will lead to insufficient fresh air entering the cylinder, which will affect the fuel atomization, oil and gas. The degree of mixing and combustion quality have a certain impact, resulting in a decrease in output power, insufficient torque, and increased emissions; in addition, this kind of throttle valve is more complicated, occupies a larger volume, and increases the cost
