大众排放门事件让在美各大车企风声鹤唳,研发涡轮增压车型无疑是个明智的选择由于涡轮引擎工作中产生的最高爆发压力和平均温度非常高,从而使发动机的机械性能、润滑性能受到影响,而且保养成本也相对较高。同时还会发生涡轮迟滞现象——发动机在低转速时,由于产生废气量低,不足以带动涡轮的运转,需要等到发动机转速提高之后,废气动力较大时,涡轮才能启动。 Volkswagen’s door to the release of the major car manufacturers in the United States, the development of turbocharged models is undoubtedly a wise choice Turbofan engine work due to the highest explosion pressure and the average temperature is very high, so that the engine mechanical properties, lubrication performance affected , But also the maintenance costs are relatively high. Turbine hysteresis can occur at the same time - the engine at low speed, due to low exhaust gas generated, not enough to drive the operation of the turbine, the need to wait until the engine speed increases, the exhaust gas is larger, the turbine can start.
