近年来,农村小型沼气电(动力)站发展很快,但一些用户或机手对双燃料(沼气、柴油)发动机常见的故障原因分析不透、判断不准、排除方法不当,使机组没能发挥应有的功率和效益。本文仅就四种常见的故障原因及排除方法分析介绍如下:一、启动带不起负荷,排气管冒黑烟,甚至熄火原因是发动机启动时,机器温度低,尤其是冬天,润滑不良,摩擦系数大,带负荷运转,造成机器冒黑 In recent years, rural small-scale biogas (power station) has developed rapidly, but some users or hand-engine analysis of common causes of dual fuel (biogas, diesel) engine imperfect, not allowed to judge, to exclude improper method to make the unit failed Play due to the power and effectiveness. This article only on the four common causes of failure and analysis of the exclusion method are described below: First, start with no load, exhaust black smoke, or even turn off the engine is started, the machine temperature is low, especially in winter, poor lubrication, Large friction coefficient, with load operation, causing the machine black
