摘　　要：发动机燃用气体燃料时,充气效率降低,使发动机最大功率及扭矩下降。为提高燃气发动机的动力性,可对其进气系统进行谐振增压。在进气调谐系统的开发中设计了一种新型阀门,该阀门与目前常用的阀门相比,流通阻力减小,结构简单,安装方便,更具实用性。改装后的发动机,最大转矩比原机至少提高了11.8%,最大转矩工况的燃油消耗率比原机降低了4g/(kW.h)。改装系统可适用于多种燃料发动机及汽油机。For a gas fuel engine,the decrease in volumetric efficiency will reduce the engine's maximum torque and power.To improve the engine's performance,a new resonant intake system is designed,in which the newly designed valve,both simple and economical,can effectively reduce the circulating resistance.Furthermore,experiments show that,after being modified,the engine's maximum torque can increase by at least 11.8%,and its BSFC(Brake Specific Fuel Consumption) at maximum torque can reduce by 4g/(kW·h).The modified intake system can be applied to various gas fuel engines and gasoline engines.
