增压技术是内燃机节能减排的关键技术，排放法规的日益严格和燃油经济性指标的不断提升，对增压系统提出了更高的要求。针对满足未来排放法规的车用增压技术，如可变几何截面涡轮增压、二级涡轮增压、复合增压、电辅助涡轮增压以及压气机技术进行了简单概述。所介绍的几种增压技术，都能在一定程度上提高低速转矩、改善瞬态响应以及降低污染物排放，但都不可避免带来成本增加、结构复杂、控制难度大、安装空间受限等问题，没有一种标准的增压方式可以很好地解决上述问题。因此，选择合适的增压方式以满足未来的排放法规需权衡上述利弊。可变几何截面涡轮增压、二级增压、电辅助增压、先进的压气机技术等的相互组合将是未来增压技术的发展方向之一。

The boosting technology is a promising way to improve the efficiency of internal combustion engine and reduce emissions.As the emission regulations become more stringent and the fuel economy index goes up,higher requirements will be put forward to the boosting systems.The aim of this paper is to provide a brief overview a-bout the vehicle charging technologies which could meet the future emission regulations such as variable geometry turbocharging,two-stage turbocharging,hybrid dual -stage boosting,electric assisted turbocharging and the compressor technology.The several boosting technologies which have been introduced could increase the low-end torque and improve the transient response and reduce emissions to a certain extent,but they will inevitably bring some problems such as expensive cost,complicated structure,complex control,complicated packaging,et al.There is not a standard solution of boosting technology which could solve the above problems very well. Therefore,it's needed to weigh the above advantages and disadvantages when choosing the boosting system suit-ably to meet the future emission regulations.Combined variable geometry turbocharging,two-stage turbocharg-ing,electrically assisted turbocharging,advanced compressor technologies,etc.will be one of the development directions of future boosting technologies.
