柴油机在高原地区使用时,由于随着海拔高度的增加,大气密度减小和气压下降,使发动机充气效率不足,混合气变浓,致使发动机燃烧不完全,功率下降,油耗剧增.如695Q型柴油机在平原设计出厂时最大功率为105马力,耗油率为192克/马力小时,最大扭矩为31公斤·米.不做任何调整在海拔2240公尺 When using diesel engine in the plateau area, as the altitude increases, the atmospheric density decreases and the barometric pressure decreases, the engine charging efficiency is insufficient and the mixture becomes thicker, resulting in incomplete combustion of the engine, power loss and sharp increase in fuel consumption. Diesel engine in the plain design factory maximum power of 105 horsepower, fuel consumption was 192 g / h horsepower, the maximum torque of 31 kg · m. Without any adjustment at an altitude of 2240 meters
