大家知道,增压是改进内燃机技术-经济性能最有效的手段之一。但是,直至不久以前,仅在柴油机上广泛采用增压,而在汽油机上几乎没有应用增压,其原因为: (1) 以前汽油价格较低时,汽油机即使不采用增压,其性能指标,包括燃油消耗率也可以满足用户要求。 (2) 增压器零部件的可靠性不够高,重量重,成本高,因此,把它装在小型汽油机上不能抵补与此有关的消耗。 As we all know, supercharging is one of the most effective ways to improve internal combustion engine technology - economy performance. However, it was not long ago that supercharger was widely used on diesel engines and almost no supercharging was applied to gasoline engines because: (1) Gasoline engines, even at low gasoline prices, Including fuel consumption rate can also meet user requirements. (2) The reliability of the turbocharger components is not high enough, the weight is heavy and the cost is high. Therefore, installing it on a small gasoline engine can not offset the related consumption.
