摘要 提高内燃机气缸压力,有助于提高内燃机升功率,增大膨胀输出功,提高能量转化效率即内燃机热效率。因此,提高内燃机气缸压力一直是内燃机领域的工作重心和发展方向之一。对近年来内燃机气缸压力的发展状况进行了概述,分析了缸内爆发压力的研究进展、提高内燃机气缸压力的技术措施及新型燃烧方式下气缸压力的发展,并对未来内燃机气缸压力的发展进行了展望。 Enhancing cylinder pressure is conductive to improve power per liter and enlarge expansion output work and enhance thermal efficiency, which has become the main work and development direction in the area of internal combustion engines. This paper briefly summarizes the development of cylinder pressure in recent years. Besides, this paper summarizes the development of maximum cylinder pressure and gives the common methods of enhancing cylinder pressure further and generalizes the development of cylinder pressure in new combustion modes. Finally, this paper predicts the development tendency of cylinder pressure.
