柴油机功率不足，即柴油机发不出应有的功率，主要表现在满负荷（或较大负荷）时，转速明显下降；工作中不能牵引额定的机组（农具）作业，行驶速度降低，加速性能差，排气管冒黑烟，有敲击声，温度过高等。柴油机能否发出应有的功率、主要决定于气缸内燃油燃烧的质量。而影响? Diesel engine power is insufficient, that is, the diesel engine can not generate its own power, mainly at full load (or greater load), the speed dropped significantly; work can not be traction rated unit (farm tools) operation, driving speed, poor acceleration performance , Exhaust black smoke, percussion, temperature is too high and so on. Diesel engine can issue the appropriate power, mainly depends on the quality of the fuel combustion in the cylinder. The impact?
