Problems solved by technology

[0003] In the previous air intake volume control device of the engine, since the bypass control system such as the bypass valve, the actuator and the sensor are not all installed on the throttle section, that is, the bypass control system is not completed, and if there is no After the assembly of the entire device is completed, the function check of the bypass control system cannot be carried out
If this inspection fails, the bypass valve, the actuator, and the sensor have to be disassembled from the throttle section, and replaced with other parts before inspection, which has to be very troublesome. barriers to increasing productivity

Embodiment Construction

[0036] Embodiments of the present invention will be described below with reference to the drawings.

[0037] First, in Figure 1 ~ Figure 3 Among them, motorcycle 1 is a kind of small motorcycle, and it uses tandem type seat 2 double as lid and is used, and power unit 4 is provided with right below the trunk 3 that is long in the front and rear direction. The power unit 4 is composed of an engine 5 with a cylinder block 6 greatly tilted forward, and a continuously variable transmission 8 integrally connected with a transmission case 10 extending rearward from one side of the crankcase 9 of the engine 5 , and a rear wheel 16 as a drive wheel is pivotally supported on the rear end portion of the gearbox case 10.

[0038] On the frame 11 of the motorcycle 1, at the connecting parts connecting the pair of left and right upper frames 11a, 11a supporting the trunk 3 and the upwardly facing rear ends of the pair of left and right downpipes 11b, 11b extending from the front pipe. , ...

Abstract

In an intake air-amount control system for an engine, a coupler (80) is integrally formed on a control block (28) coupled to a throttle body (17), and a bypass valve (35), a sensor (64, 73, 76) and an actuator (39) are mounted in the control block (28). An electronic control unit (84), is placed on an outer end face of the control block (28), and a synthetic resin (103) is potted into a cap (101) mounted to the control block (28) to cover the electronic control unit (84), so that the electronic control unit (84) is wrapped, and a mounted portion of the cap (101) is sealed. Thus, the inspection of the functions of the bypass control devices can be carried out before assembling of them to the throttle body, leading to an enhancement in productivity.

Description

technical field [0001] The present invention relates to the improvement of the air intake volume control device of the engine. A bypass channel connected to the gas channel; a bypass valve to control the opening of the bypass channel; a sensor to detect the running state of the engine; an actuator to drive the bypass valve to open and close according to the signal output by the sensor. Background technique [0002] An intake air amount control device of this type of engine is known, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-303164. [0003] In the previous air intake volume control device of the engine, since the bypass control system such as the bypass valve, the actuator and the sensor are not all installed on the throttle section, that is, the bypass control system is not completed, and if there is no After the assembly of the entire device is completed, the function check of the bypass control system cannot be performed. If this inspectio...
