How to Adjust the Fuel Supply of Guo Si EFI Motorcycle

The ECU data needs to be refreshed to adjust the fuel supply of the fourth EFI motorcycle.

Because the engine is running under load when the motorcycle is running, at this time, it is necessary to use rich mixture to obtain more power. The computer ECU will judge the load of the engine according to the throttle opening or air intake, and adjust the fuel injection quantity in time.

The basic principle of EFI motorcycle is that the carburetor device is cancelled by EFI system device, and the fuel supply and ignition of the engine are intelligently controlled by microcomputer with EFI special software, which is extremely accurate, so that the engine can reach the best air-fuel ratio and ignition angle at any time under any working condition and any environment. Thereby reducing the fuel consumption of the motorcycle, improving the emission and greatly improving the comprehensive performance.

The EFI device of motorcycle engine generally consists of fuel injection circuit, sensor group and electronic control unit.

Working principle of EFI system

The electronic fuel injection system takes the electronic control device ECU as the control center, uses various sensors installed in different parts of the engine and the vehicle to measure various working parameters of the engine, and controls the fuel injection pump to accurately control the fuel injection time through the set control program and data, so that the engine can obtain the best fuel injection time under various working conditions.

Meet the requirements of output torque, low fuel consumption and emission guarantee. The parts of the electronic control system include ECU, various sensors and controller components on the fuel injection pump, and glow plug.
