高原环境下米勒循环对柴油机燃烧效率和排放的影响

The Influence of Miller Cycle on Combustion Efficiency and Emissions of Diesel Engines in High-altitude Environments

在高原地区,由于空气稀薄和极端天气的影响,导致内燃机的性能受到了影响,其中燃烧效率和排放问题更加突出。近年来,随着排放法规的严格要求及柴油机动力性能的影响,米勒循环逐渐引发工业界和学术界的广泛关注。文章针对高原环境下柴油机运用米勒循环的实际效果进行了深入探讨,通过对比高海拔地区(3000~5000 m)和低海拔地区(0~2000 m)下柴油机的运行数据可知,米勒循环在高海拔地区能有效改善柴油机的燃油经济性,同时可以显著降低NO_(x)等有害排放物的生成,对于高原地区的可持续发展具有重要的意义。

In high-altitude areas,the performance of internal combustion engines is affected by thin air and extreme weather conditions,with combustion efficiency and emissions issues becoming more prominent.In recent years,with the strict requirements of emission regulations and the impact of diesel power performance,the Miller cycle has gradually attracted widespread attention from industry and academia.The article delves into the practical effects of using Miller cycle on diesel engines in high-altitude environments.By comparing the operating data of diesel engines in high-altitude areas(3000-5000 m)and low altitude areas(0-2000 m),it can be seen that Miller cycle can effectively improve the fuel economy of diesel engines in high-altitude areas,while significantly reducing the generation of harmful emissions such as NO_(x),which is of great significance for the sustainable development of high-altitude areas.
