Embodiment 1

[0019] Such as figure 1 As shown, the present invention has a longer service life idle speed adjustment throttling structure, including a throttle body 1, a main throttle passage 2 and a bypass airflow passage 3 are opened in the throttle body 1, and the bypass airflow passage 3 and An idle speed adjustment block 4 is also provided at the intersection of the main throttle passage 2, and the idle speed adjustment block 4 is connected with the idle speed adjustment screw 5 installed on the throttle body 1, and the idle speed adjustment block 4 is adjusted by adjusting the idle speed adjustment screw 5. Control the size of the airflow gap at the intersection of the bypass airflow channel 3 and the main throttling channel 2; After the airflow enters the bypass airflow passage 3 from the intake end, as the space gradually increases, the airflow pressure gradually decreases, and the impact force on the inner wall of the idle bypass passage 3 also gradually decreases, thereby solving...

Embodiment 2

[0021] Such as figure 1 As shown, the present invention has a longer service life of the idle speed adjustment air-saving structure. On the basis of Embodiment 1, the contact surface between the idle speed adjustment block 4 and the bypass air passage 3 is arc-shaped.

Embodiment 3

[0023] Such as figure 1 As shown, the present invention has a longer service life of the idling speed adjustment air-saving structure. On the basis of Embodiment 1, taking the centerline of the bypass airflow passage 3 as the axis, the inner diameter slope of the bypass airflow passage 3 is ±30° .

Abstract

The invention discloses an idling adjusting throttle structure with the long service life. The idling adjusting throttle structure comprises a throttle body, a main throttle channel and a bypass airflow channel are formed in the throttle body, an idling adjusting block is arranged at the joint between the bypass airflow channel and the main throttle channel and connected with an idling adjusting screw installed on the throttle body, and the idling adjusting block controls the size of the airflow gap at the joint between the bypass airflow channel and the main throttle channel by adjusting the idling adjusting screw, and the inner diameter of the bypass airflow channel is linearly increased towards the idling adjusting block. The problem that abrasion to the inner wall of an idling bypass channel of an existing throttle body is large in the using process, and therefore an idling adjusting screw cannot accurately adjust the air inflow for a long time is solved.

Description

technical field [0001] The invention relates to an automobile part, in particular to an idle speed regulating air-saving structure with a long service life. Background technique [0002] The throttle body is a valve that controls how much air the engine takes in. It is a circular steel sheet with a shaft in the middle, which is connected to and controlled by the throttle cable. The throttle body is a device on the engine's air intake system. [0003] The throttle body is composed of a throttle valve, a bypass vent hole, etc., and the throttle valve is used to control the intake air volume of the main throttle channel under the normal operating conditions of the engine. Since the EFI system usually closes the throttle valve fully when the engine is idling, a side air passage is provided to supply a small amount of air when the engine is idling. The rotational speed of the engine at idle speed is determined by the amount of air supplied at this time. Since the air goes thro...
