较较1000系列沼气发动机配备全数字电控系统。相对于传统的点火+调速的控制系统，全数字电控系统新增燃料控制系统，使整体系统可靠性更好，控制精度高，功率更大，易于调试维修及批量生产。固化在ECU内的控制软件及机器特性数据，保证了批次产品的一致性。 不仅如此，全数字电控系统还能更好的适应不同季节沼气中的甲烷含量。配合沼气专用的燃料调节部件可以使沼气发电机组达到与天然气相当的发电功率。
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.
较点火系统由点火线圈、高压线、火花塞组成，点火角度依据发动机的转速、温度、输出功率进行调整，以保证发动机在各种负荷、不同季节下处于佳状态，并延长发动机的使用寿命和提高发电效率。
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.

较调速系统由电子节气门执行，他们均由ECM（发动机控制模块较控制。ECM 通过4个传感器测量发动机的进气压力、温度，转速，冷却水温度，计算发动机的进气量，并结合内部标定的确定点火时刻以保证发动机的动力性和燃料经济性；通过电子节气门调节进气量，使发动机在目标转速上稳定运行。
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.
较 燃料系统选用意大利madas调压器及较impco混合器。系统会依据发动机进气流量自行调节燃料供应量。使空燃比在发动机从启动到大负荷期间保持在合适的范围。
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.
较系统选用德国BOSCH进口传感器，德国大陆电子节气门，为特定发动机定制的专用线束和高压线。保证发动机可靠点火。ECM采用引进技术生产，选用进口元器件，可以长期运行在90摄氏度。并可以承受110摄氏度的温度，可保证发动机可靠运行。
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.
