车用柴油机停缸技术研究综述
|
摘要
介绍了车用柴油机的停缸技术,以及该技术在降低油耗及排放相关领域的优势,同时阐述了目前限制其应用所面临的技术性问题,并进行了总结与展望。停缸技术可使得柴油机在低负荷工况下显著降低其油耗率,同时可通过提升排气温度来改善催化转化器的处理效果,从而降低排放。尽管目前停缸技术的应用仍受到NVH等相关技术的限制,但随着技术的不断完善,其在车用柴油机动力领域依然有着广阔的应用前景。
The cylinder deactivation technology of vehicle diesel engine and the advantages of this technology in the fields of reducing fuel consumption and emissions were introduced. At the same time, the technical problems that limit its application were expounded, and the prospects were summarized. The cylinder deactivation technology can significantly reduce the fuel consumption of the diesel engine under low load conditions, and at the same time improve the treatment efficiency of the catalytic converter by increasing the exhaust gas temperature, there by reducing emissions. Although the application of the current cylinder deactivation technology is still limited by NVH and other related technologies, with the continuous improvement of technology, it still has broad application prospects in the field of vehicle diesel engine power.
