為什么瓦斯發電機組時間用長了達不到額定標準的功率，而且所帶負載量降低。以下功率不足的故障原因及解決方案：

Why does the gas generator unit not reach the rated standard power for a long time, and the load is reduced. The following fault causes and solutions for insufficient power:

一、燃油壓力低。查明油箱中有無燃油。檢查油箱到輸油泵之間供油管路有無泄漏或凹癟的彎曲處檢查有無空氣進入燃油系統，燃油控制閥是否卡信，粘住或失效。檢查燃油壓力。發動機全負荷運轉時，燃油輸油泵出口壓力zui低應為415kPa，如燃油壓力低于上述壓力，應更換燃油濾清器濾芯。油壓仍低時，則需檢查燃油輸油泵。

1、 Low fuel pressure. Find out if there is fuel in the tank. Check the fuel supply pipeline from the fuel tank to the fuel pump for leakage or concave bend. Check whether air enters the fuel system and whether the fuel control valve is stuck, stuck or invalid. Check the fuel pressure. When the engine operates at full load, the outlet pressure Zui of the fuel transfer pump shall be 415kpa. If the fuel pressure is lower than the above pressure, the fuel filter element shall be replaced. If the oil pressure is still low, check the fuel transfer pump.

二、氣門間隙不對。調整氣門間隙。

2、 The valve clearance is not correct. Adjust the valve clearance.

三、燃油品質差。排放油箱內燃油，更換燃油濾芯。給油箱中加入優良燃油。

3、 Poor fuel quality. Drain the fuel in the fuel tank and replace the fuel filter element. Fill the fuel tank with high-quality fuel.

四、功率調定太低。按發動機品牌上的技術規格調整發動機功率。

4、 The power setting is too low. Adjust the engine power according to the specifications on the engine brand.

五、渦輪增壓器積炭。檢查渦輪增壓器，必要時修理。

5、 Carbon deposits on the turbocharger. Check the turbocharger and repair it if necessary.

六、檢查進氣歧管壓力。檢查空氣濾清器有元堵塞。

6、 Check the intake manifold pressure. Check whether the air filter is blocked.

七、空氣濾清器阻塞。

7、 The air filter is blocked.
