代表着火过程长短的滞燃期对柴油机燃烧性能有重大影响。因着火过程本身比较复杂,所以长期以来受到内燃机研究人员的重视,他们从物理和化学两方面对着火延迟时期做了大量的计算和试验工作。本文在对前人工作分析的基础上提出了研究着火过程和计算滞燃期的新方法。1着火过程和滞燃期研究的发展自Tizard等人测出着火滞后以前,最早的观点认为柴油机中燃油着火前不需要蒸发,即
The duration of the burn, which represents the duration of the fire, has a significant impact on the combustion performance of the diesel engine. Because of the complexity of the ignition process itself, it has long been the focus of ICE researchers, who have done a great deal of computational and experimental work on both the physical and chemical aspects of the fire delay. Based on the analysis of previous work, this paper proposes a new method to study the process of ignition and calculate the retardation period. 1 Ignition process and development of retarding period Since Tizard et al. Determined the retardation of lag, the earliest point of view did not require vaporization of the fuel in the diesel engine before ignition
