燃烧室内混合气体的压力、温度、浓度任何一项达不到着火要求,都会造成柴油机着火困难。一、压力柴油机燃烧室的压力,取决于气门下陷量、密封性能和气缸套与活塞、活塞环的配合间隙。最简单的确诊方法:不打减压,手摇把摇转曲轴,摇不动(转)为密封性能良好,反之则表明燃烧室密封
Combustion chamber of mixed gas pressure, temperature, concentration of any one less than the fire requirements, will cause the diesel engine fire difficulties. First, the pressure Diesel engine combustion chamber pressure, depending on the amount of valve sag, sealing performance and cylinder liner and piston, piston ring with the gap. The easiest way to diagnose: do not fight decompression, cranking crankshaft, shake (transfer) for the sealing performance is good, on the contrary that the combustion chamber seal
