Problems solved by technology

However, due to the change to open-loop control, the electronic control unit 131 cannot correct and control the fuel injection quantity according to the feedback signal from the oxygen sensor (not shown in the figure), resulting in difficulty in air-fuel ratio control and high pollution

Embodiment Construction

[0016] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with accompanying drawings.

[0017] Before the present invention is described in detail, it is noted that in the following description, similar components are denoted by the same reference numerals.

[0018] refer to image 3 and Figure 4 , the preferred embodiment of the control method for reducing the emission of injection engine motorcycles in the present invention includes a setting step 200 , a detection step 202 , and a control step 204 .

[0019] The installation step 200 is to install the oxygen sensor 32 on the exhaust pipe 36 and between the negative pressure air device 33 and the muffler 34 . Wherein, the negative pressure air device 33 is connected with the engine 35 with the negative pressure pipe 37, and is driven by the negative pressure of the engine 35.

Abstract

The invention relates to a controlling method for reducing pollution emission of a jet-type engine motorcycle. The method comprises the steps of a setting step, a detection step and a control step. The setting step, during which, an oxygenic sensor is arranged between an air device and a muffler. The detection step, during which, an electronic control unit is used to detect the rotational speed of an engine and the opening degree of an accelerograph. The control step comprises a judging step, a medium-low speed control step and a high speed control step. The air device is used to fit the oxygenic sensor; in the low speed control step, closed loop control is adopted; both the riding smoothness and pollution emission reduction are considered; as the closed loop control is adopted, the electronic control unit can adjust and amend a feedback signal of the oxygenic sensor at any moment.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for reducing the emission of jet engine motorcycles. Background technique [0002] figure 1 It is an existing control method for reducing the emission of jet engine motorcycles, including a detection process 11 and a control process 12 . The control process 12 includes a medium-low speed process 121 and a high-speed process 122 . In the detection process 11, an electronic control unit (Electronic Control Unit, ECU) 111 detects the engine speed 112 and the throttle opening 113 of the injection engine motorcycle to adjust the air-fuel ratio. When the engine speed 112 and the throttle opening are When 113 is less than a certain value, enter low-medium speed process 121, and enter high-speed process 122 when engine speed 112 and throttle opening 113 are greater than this fixed value. When in the middle and low speed process 121, the electronic control unit 111 adjusts the amoun...
