Compared with 1000 series biogas engine, it is equipped with full digital electronic control system. Compared with the traditional ignition+speed control system, the new fuel control system is added to the full digital electronic control system, which makes the overall system more reliable, high control accuracy, greater power, and easy to debug, repair and mass production. The control software and machine characteristic data solidified in ECU ensure the consistency of batch products. Moreover, the all-digital electronic control system can better adapt to the methane content in biogas in different seasons. The biogas generator unit can achieve the power generation equivalent to natural gas by cooperating with the special fuel regulating components for biogas.
The ignition system is composed of ignition coil, high-voltage wire and spark plug. The ignition angle is adjusted according to the engine speed, temperature and output power to ensure that the engine is in good condition under various loads and seasons, and to extend the service life of the engine and improve the power generation efficiency.
The speed control system is implemented by the electronic throttle, which is controlled by the ECM (engine control module). The ECM measures the intake pressure, temperature, speed and cooling water temperature of the engine through four sensors, calculates the intake volume of the engine, and determines the ignition time in combination with the internal calibration to ensure the power and fuel economy of the engine. The intake volume is adjusted by the electronic throttle to make the engine run stably at the target speed.
Italian madas pressure regulator and Impco mixer are selected for comparison fuel system. The system will automatically adjust the fuel supply according to the engine intake flow. Keep the air-fuel ratio in a proper range during the engine from starting to heavy load.
The system uses imported sensors from BOSCH in Germany, electronic throttle in Germany, and special harness and high-voltage wire customized for specific engines. Ensure reliable ignition of the engine. ECM is produced with imported technology and imported components, which can operate at 90 ℃ for a long time. It can also withstand the temperature of 110 ℃, which can ensure the reliable operation of the engine.
