摘要
废气涡旋增压器采用了一种新型增压原理及技术 ,将目前截然不同的两种增压方式涡轮增压与机械增压技术融合起来。本文全面介绍了废气涡旋增压器的原理、单涡圈与双涡圈的几何理论、涡圈参数的工程设计方法。对于废气涡旋增压器优缺点作了比较全面的评价 。
Exhaust gas vortex supercharger adopts a kind of new supercharging principles and techniques.It merges both the turbocharging and mechanically supercharging techniques which are entirely different in supercharging methods.This paper comprehensively introduces the principles of exhaust gas vortex superchargers,geometric theory about single vortex circle and double vortex circle,and engineering design method of vortex parameters.The merits and shortcomings of exhaust gas vortex supercharger are evaluated rather comprehensively.The direction for deeply investigating the engineering applications of exhaust gas vortex superchargers are pointed out by the end of the paper.
