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(diào)速系統(tǒng)由電子節(jié)氣門執(zhí)行，他們均由ECM（發(fā)動機控制模塊較控制。ECM 通過4個傳感器測量發(fā)動機的進(jìn)氣壓力、溫度，轉(zhuǎn)速，冷卻水溫度，計算發(fā)動機的進(jìn)氣量，并結(jié)合內(nèi)部標(biāo)定的確定點火時刻以保證發(fā)動機的動力性和燃料經(jīng)濟(jì)性；通過電子節(jié)氣門調(diào)節(jié)進(jìn)氣量，使發(fā)動機在目標(biāo)轉(zhuǎn)速上穩(wěn)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.

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.
