为什么瓦斯发电机组时间用长了达不到额定标准的功率，而且所带负载量降低。以下功率不足的故障原因及解决方案：

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、燃油压力低。查明油箱中有无燃油。检查油箱到输油泵之间供油管路有无泄漏或凹瘪的弯曲处检查有无空气进入燃油系统，燃油控制阀是否卡信，粘住或失效。检查燃油压力。发动机全负荷运转时，燃油输油泵出口压力zui低应为415kPa，如燃油压力低于上述压力，应更换燃油滤清器滤芯。油压仍低时，则需检查燃油输油泵。

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、气门间隙不对。调整气门间隙。

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

三、燃油品质差。排放油箱内燃油，更换燃油滤芯。给油箱中加入优良燃油。

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、功率调定太低。按发动机品牌上的技术规格调整发动机功率。

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

五、涡轮增压器积炭。检查涡轮增压器，必要时修理。

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

六、检查进气歧管压力。检查空气滤清器有元堵塞。

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

七、空气滤清器阻塞。

7、 The air filter is blocked.
