oil atomization

The physical model of intake and exhaust system and the mathematical model of air-fuel atomization were built,the characteristics and relative parameters during the course of mixture formation were calculated in detail,and the process and influencing factors of fuel spray evaporation and mixture formation inside compound intake and exhaus.

建立了研究对象的物理模型和空气—燃油雾化混合的数学模型,对HCCI柴油机混合气形成过程特点与相关参数进行了详细的数值计算,并对复合式进排气系统内柴油喷雾蒸发和混合气形成过程以及影响因素进行了分析。

This paper proposes a new fuel atomization concept using dissolved gas.

本文提出了一燃油溶气雾化新概念，它完全不同于常规燃油雾化方法，通过溶气在喷孔内的析出产生气爆效应，使燃油喷注是抛物形状，大大提高了燃油雾化质量。

In this paper,the research of the tiny-oil ignition technology are divided into four segments according to it fundamental principle: fuel pulverization,fuel combustion,coal powder concentration,coal powder combustion,then every se.

本文依据微油点火技术的基本原理,把研究内容总体上划分为四个部分:燃油雾化、油滴燃烧、煤粉浓缩、分级引燃;然后分别对这四个部分进行了数值模拟和优化设计,并在雾化喷嘴设计参数、油燃烧器配风方式、煤粉浓缩器角度等方面得出了一些结论。

The fuel atomization gets more attention.
