Electric Single Wheel Barrow-SINGLE WHEEL WITH REAR STAND
Service&Support
Electronic Control Unit (ECU) collect a variety of sensor signals to control the fuel injection and ignition of engine by calculation, then make the engine hybrid gas concentration and the ignition timing always at the best condition to have a best performance.
When the motorcycle malfunction, firstly check if it is EFI System Fault. If so, then according to the flow shown below to find the specific cause of the failure.
Notice:
(1)When every motorcycle run 5000 kilometers, the fuel filter should be replaced, Note: You must use the same with the original EFI special filter, the fake filter will result in clogs;
(2)EFI system connected to the battery must be solid and reliable; high-pressure fuel injection and ignition wire harness lashing to keep more than 2 cm distance, otherwise it will lead to job insecurity EFI;
(3)The interference type ignition coil must be used, the resistance value should be between 5KΩ ~ 8KΩ;
(4)You must use qualified rectifier, otherwise it will lead to job insecurity EFI judging method: remove the fuse after the engine start, the engine idle normally, pull throttle acceleration is adequate, qualified;
(5)Oil can not be too much, otherwise there will be idle smoke, and damage the oxygen sensor.
Annex 1 idle air adjustment method
When idling unstable easily when flame out fault, try to adjust the idle volume:
1. Pull the throttle to maximum opening; 2 key to open, release the accelerator within two seconds,then system enters into debug mode;Start the engine, pull throttle fully to heat engine until the ECU 4 lights appear slowly release the throttle to idle position after alternating light and dark(the concentration of oxygen into the closed loop state );If the speed is less than 1600 rev / min, indicating that the idle volume is too small, adjust the idle air adjusting screw counterclockwise, if speed over 1800 adjusted clockwise to stabilize for about 30 seconds before the end of the off key.
Annex 2 restore the factory settings method
In special cases, there may be self-EFI system error, the engine will speed up weakly, the tempering blasting and other issues, you can try a factory reset:1. Pull the throttle to maximum opening; 2 Turn on the switch until the instrument failure light turn off (after listening the electromagnetic fuel pump stop working) release the throttle; 3 Turn off the switch.In this case,the value of self-learning EFI System restore to factory default settings.
Then you had better arrange a self-learning process again: Select a good road, gradually ascend throttle acceleration, deceleration and then descending, the point is trying to change the throttle slowly, so that each throttle opening have been self-learning opportunities, the process It can be repeated several times, until you feel good, finally complete with key off.
