Could you tell me the fuel injection pulse when Sail is idling normally?

A very important problem that needs attention is the fuel injection mode of the engine.

If the battery adjustment mode is entered, the fuel injection time will be extended.

Battery voltage adjustment mode: When the battery voltage is too low, the ECM will enter the battery adjustment mode, which will prolong the opening time of the fuel injector. The lower the battery voltage, the longer the fuel injection time.

The above is a way to assemble MPFI system for C 16NE engine of Sail car.

Check whether it reaches 14 volts. If it does not reach the estimated value, it will enter this mode.

Once the battery or charging system of many old cars is broken, it is estimated that the fuel injection time will be extended. High water temperature at idle speed, fan rotation, low voltage and poor grounding of old vehicles will all cause ECM to enter this mode. I don't know if it's right. Let's discuss it.
