现如今研制高效率低污染的发动机是进入21世纪以来世界各国所极力追求的目标。鉴于柴油机的节能、高效、经济实用以及大转矩的诸多特点,汽车开始越来越多的以柴油机作为动力。研究柴油机的燃烧过程,尽可能的提高其动力性和经济性等性能,降低NOx和碳烟等有害物质的排放,已经成为一项很有意义的工作。除传统的燃烧过程的研究试验方法之外,内燃机燃烧过程的数值模拟是建立在试验基础上的一项强有力的措施。
本文主要在多维模拟的理论基础上,应用AVL公司开发的三维数值模拟FIRE软件对12V240ZJE型柴油机其燃烧过程在实验的基础上进行了进一步的模拟计算与分析,对燃烧室的形状及其喷射参数进行改进,使该样机达达到更好的排放标准。
(1)、本文结合内燃机的燃烧过程运用AVL公司开发的三维数值模拟FIRE软件系统的描述柴油机缸内气流运动过程、喷雾过程和燃烧过程进行模拟仿真计算。
(2)、最后对缸内燃烧过程进一步的深入研究进行了展望。
关键词:发动机 直喷式柴油机 燃烧 数值模拟 排放。
Abstract
Nowadays the development of high efficiency and low emissions engine is since twenty-first Century the world to pursue the goal of. In view of diesel engine energy-saving, efficient, economical and practical as well as large torque characteristics, the car began more and more to the diesel engine as power. Research on diesel engine combustion process, as far as possible to improve the power and economy performance, reduce NOx and carbon smoke emissions of harmful substances, has become a very meaningful work. In addition to the traditional study on combustion process in internal combustion engine test method, numerical simulation of the combustion process is established based on the test of a strong measures.
This paper mainly in multidimensional modeling on the basis of the theory, application of AVL company developed numerical simulation software of FIRE12V240ZJE diesel engine combustion process on the basis of experiments for further simulation and analysis, the combustion chamber shape and injection parameters were improved, so that the prototype to achieve better emission standard.
(1), combined with the combustion process by AVL company developed 3D numerical simulation FIRE software system is described in the diesel engine cylinder air motion process, spray and combustion process simulation calculation.
(2), at the end of the combustion process in cylinder further research prospect.
