本文分析了直喷式柴油机燃烧的混合气形成和放热规律的基本特征及其对燃烧的 粗爆性和烟度的影响。文中指出改变柴油机燃烧基本特征的研究方向是以油膜雾化燃 烧为手段．采取必要措施使缸内着火前将燃油全部喷完，控制在靠近上死点处着火， 以实现近似地等压燃烧。实践证实．新的燃烧方式在降低爆压、改善烟色和提高经济性等方面均取得良好的效果。为进一步改善小型、高速、直喷式柴油机燃烧性能。试 验伞喷油膜雾化燃烧有着广阔的发展前途。
This paper analyzes the basic characteristics of the formation and exothermic evolution of direct injection diesel engine combustion mixture and its impact on the combustion of the rough burst and smoke. The paper points out that the research direction of changing the basic characteristics of diesel combustion is to use oil film atomization and combustion as a means. Take all necessary measures to extinguish the fuel in the cylinder before it is completely extinguished, and control the ignition near the upper dead center to achieve approximately equal pressure combustion. Practice confirmed. The new combustion method has achieved good results in reducing explosion pressure, improving smoke color and improving economy. To further improve the small, high-speed, direct injection diesel combustion performance. Experimental umbrella spray film atomization combustion has broad prospects for development.
