摘要
为了提高491QE汽油机的性能,进行了增压系统的开发工作。通过计算确定了增压参数,并在原发动机基础上设计了定压排气管和脉冲转换排气管两种增压系统。利用循环模拟程序计算了491QE汽油机增压以后的性能。结果表明,脉冲转换系统在发动机废气能量的利用方面优于定压系统。
The turbocharging system for 491QE gasoline engine was undertaken in order to improve the engine's performance. With the requirement for the turbocharged engine, the parameters of the turbocharger was computated. Based on the engine, two exhaust systems, the constant pressure manifold and the pulse converter manifold, were desinged. The simulation of the turbocharged gasoline engine was carried out and the results show the pulse converter system can utilize the exhaust energy better than the constant pressure system.
