較較1000系列沼氣發動機配備全數字電控系統。相對于傳統的點火+調速的控制系統，全數字電控系統新增燃料控制系統，使整體系統可靠性更好，控制精度高，功率更大，易于調試維修及批量生產。固化在ECU內的控制軟件及機器特性數據，保證了批次產品的一致性。 不僅如此，全數字電控系統還能更好的適應不同季節沼氣中的甲烷含量。配合沼氣專用的燃料調節部件可以使沼氣發電機組達到與天然氣相當的發電功率。
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.
較點火系統由點火線圈、高壓線、火花塞組成，點火角度依據發動機的轉速、溫度、輸出功率進行調整，以保證發動機在各種負荷、不同季節下處于佳狀態，并延長發動機的使用壽命和提高發電效率。
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.

較調速系統由電子節氣門執行，他們均由ECM（發動機控制模塊較控制。ECM 通過4個傳感器測量發動機的進氣壓力、溫度，轉速，冷卻水溫度，計算發動機的進氣量，并結合內部標定的確定點火時刻以保證發動機的動力性和燃料經濟性；通過電子節氣門調節進氣量，使發動機在目標轉速上穩定運行。
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.
較 燃料系統選用意大利madas調壓器及較impco混合器。系統會依據發動機進氣流量自行調節燃料供應量。使空燃比在發動機從啟動到大負荷期間保持在合適的范圍。
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.
較系統選用德國BOSCH進口傳感器，德國大陸電子節氣門，為特定發動機定制的專用線束和高壓線。保證發動機可靠點火。ECM采用引進技術生產，選用進口元器件，可以長期運行在90攝氏度。并可以承受110攝氏度的溫度，可保證發動機可靠運行。
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.
