瓦斯發電機熱車不易啟動的幾項排查
有時瓦斯發電機組熄火后，馬上啟動會出現啟動困難，這時要檢查一下瓦斯發電機組的工作情況，看配氣系統、點火系統是否有故障，然后檢查下面幾項：
Sometimes it is difficult to start the gas generator set immediately after it is shut down. At this time, check the working condition of the gas generator set to see if the gas distribution system and ignition system have faults, and then check the following items:
1)電磁閥過熱，閥芯卡滯或磁力下降。
1) The solenoid valve is overheated, the valve element is stuck or the magnetic force drops.
2)電控插頭是否有接觸不良。
2) Check whether the electric control plug has poor contact.
3)混合器閥芯是否有卡滯現象，使混合氣過濃、過稀。
3) Check whether the valve element of the mixer is stuck, which makes the mixture too rich and too lean.
4)減壓器輸出壓力是否過高，超出正常值。
4) Whether the output pressure of the pressure reducer is too high and exceeds the normal value.
5)檢查受溫度影響的部件。
5) Check the components affected by temperature.
5.電磁閥打不開
5. The solenoid valve cannot be opened
減壓器電磁閥打不開的原因可能是以下幾點：
The reasons why the pressure reducer solenoid valve cannot be opened may be the following:
1)電源未接通或電磁閥搭鐵不好，也可能是電壓過低，啟動時壓降過大，啟動時檢查電瓶電壓，電源變換器輸出電壓是否有12V。
1) The power supply is not connected or the grounding of the solenoid valve is poor, or the voltage is too low, and the voltage drop is too large during startup. Check the battery voltage during startup and whether the output voltage of the power converter is 12V.
2)磁線圈故障，開啟功率不足。
2) Magnetic coil fault, insufficient starting power.
3)閥芯通氣孔被堵。
3) The valve element vent is blocked.
4)ECU無輸出控制信號。
4) ECU has no output control signal.
5)閥芯和鐵心的配合間隙太小，閥芯不能自由滑動。
5) The fit clearance between the valve core and the iron core is too small, and the valve core cannot slide freely.
6)閥芯O形圈或橡膠墊損壞。
6) O-ring or rubber gasket of valve element is damaged.
