Cng Lpg Ecu Factory introduces that the electronic control unit is mainly composed of two parts: hardware and software. The hardware part mainly includes system circuits, drive circuits, and input acquisition interface circuits.

  

1.System circuit: The system circuit takes the selected single-chip microcomputer as the core, mainly including storage area expansion circuit, clock circuit, reset circuit, communication circuit, etc.

2. Drive circuit: The drive circuit is mainly to amplify and drive the control signal calculated by the CPU according to the engine state and the requirements of the operator to realize the control of the oil volume control mechanism and the timing control mechanism. 

 

3. Input interface circuit: The input interface mainly amplifies, reshapes, voltage conversion, filter processing, etc. various engine signals collected from the sensor such as speed, accelerator pedal position, cooling water temperature, etc., to ensure real-time and accurate engine supply for the CPU Various parameters for the CPU to monitor.
