Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] A method for controlling the idling speed of an electric jet motorcycle, characterized in that it comprises the following steps:
[0022] a. Obtain the target idle speed value of the motorcycle engine and input it into the electronic control unit of the motorcycle. The target idle speed value refers to the engine output speed when the motorcycle is in the lowest stable running state, which is obtained through tests in advance;
[0023] b. If figure 1 As shown, on the throttle body 1 of the motorcycle engine, a bypass pipeline 3 parallel to the throttle passage 2 is preset, and the throttle body 1 appearance is facing the bypass pipeline to fix the stepping motor 4, and the stepping motor 4 is connected to the motorcycle. The electric control unit of the car is connected and controlled by it. The output shaft of the stepper mot...

The invention discloses a method for controlling electronic fuel injection motorcycle idle speed. The revolution speed of an engine and the starting state and the stopping state of an accelerator are detected so that whether the engine is in the idle speed can be judged. After the fact that the engine is in the idle speed is judged, the ventilation quantity of a bypass pipe line of a throttle valve is controlled and an ignition angular lead is controlled so that the revolution speed of the engine of the motorcycle can be adjusted to be consistent with an objective idle speed value. According to the method for controlling the electronic fuel injection motorcycle idle speed, the revolution speed of the engine of the motorcycle which is in the idle speed state can be well controlled, so that the motorcycle reaches an ideal running state of the motorcycle, the method has the advantages of being quick in response time, sensitive and quick in control, convenient and reliable to use, and capable of greatly reducing loss of the motorcycle under the idle speed state.
Description
technical field [0001] The invention relates to an electric spray motorcycle, in particular to an idle speed control method of the electric spray motorcycle. Background technique [0002] EFI motorcycle refers to a motorcycle that adopts EFI technology for ignition and fuel supply. In the electric fuel injection motorcycle, the carburetor device is canceled by the electronic fuel injection system device (EFI), and the electronic control unit (ECU) with special software for electric fuel injection is used to carry out real-time intelligent control of the fuel supply and ignition of the engine. The fuel supply is The signals measured by sensors such as throttle position sensor, intake air flow sensor, intake air temperature sensor, engine temperature sensor, crankshaft position sensor and oxygen sensor are sent to the ECU in real time, and then the ECU conducts fuel supply after comprehensive judgment. Accurate, so that the air-fuel ratio and ignition angle of the engine can ...
