把Helmholfz谐振原理应用到一台重型柴油机的进气系统上可以改善其燃烧效率和减少排气中的有害气体成份。透平增压柴油机的性能可以通过一个调谐的进气系统来提高。经调谐的进气谐振腔提供了一个改善空气流量特性的方法。增加进气空燃比改善了燃油经济性,降低了排气温度及排气中的有害成份。使最高燃烧压力如NOx排放物一样,有所增高。空气充量质量流量的增 Applying the Helmholfz resonance principle to the intake system of a heavy-duty diesel engine can improve its combustion efficiency and reduce the emission of harmful gas components. Turbocharged diesel engine performance can be improved by a tuned air intake system. The tuned inlet resonator provides a way to improve the air flow characteristics. Increasing intake air-to-fuel ratio improves fuel economy, reduces exhaust temperature and exhausts harmful components. The highest combustion pressure, like NOx emissions, has increased.
