What are the closed-loop EFI scooters?

Closed-loop EFI scooters include Wuyang Honda Jiayu, Machete, Youke, Youku, Youyue, Ruiyu, Yamaha Xunying, Qingqi Suzuki Cai Feng, Ruicai, Cai Li, Cai Yun, Haojue Suzuki Tianlong Star, Neptune, Hongbao and Tianyu.

EFI motorcycles can be roughly divided into open-loop EFI motorcycles and closed-loop EFI motorcycles:

1, closed-loop EFI motorcycle, its function and function are basically the same as that of automobile. Closed-loop EFI motorcycle can adjust the fuel injection quantity of electric nozzle according to the oxygen content in muffler, and can also change the intake pressure according to the change of external atmospheric pressure.

2. The domestic motorcycles seen on the market now are basically open-loop EFI motorcycles. The performance of open-loop EFI motorcycle is worse than that of carburetor

3. Advantages and disadvantages of motorcycle open-loop and closed-loop: open-loop is not a real EFI, it is between carburetor and EFI, and it is easier to start than carburetor; Because the closed loop is accurately supplied by ECU, it is a real EFI, which can make corresponding automatic adjustment in different environmental climates, and there will be no idling jitter of vehicles in plateau climate.

Extended data

EFI engine:

The EFI device of motorcycle engine is generally composed of fuel injection circuit, sensor group and ECU. It is divided into single-point EFI and multi-point EFI.

If the injector is installed in the original carburetor position, that is, there is only one gasoline injection point in the whole engine, this is a single-point EFI; If the injector is installed on the intake pipe of each cylinder, that is, gasoline is injected into the cylinder from multiple places (at least one injection point per cylinder), this is multi-point injection.
