本文主要论述使用空气涡流的开式燃烧室柴油机的燃烧。文章指出:如果提高空气的涡流率,而不提高燃料的贯穿力,将使燃烧效率显著降低。在中心喷射时,强的涡流减少了燃料喷雾的径向贯穿力。结果,具有过量燃料的中心区,被着火后形成的轻浮力所包围。在四英寸直径的燃烧室内,使之隔离达十分之一秒之久。在这里,用流体喷射力学的术语,对燃料喷射作了一个简单的解释,并说明了燃烧后浮力帮助燃料空气混合的环境条件。
This article focuses on the combustion of open-hearth combustion diesel engines using air vortexes. The article points out that if the eddy current of the air is increased without increasing the penetrating force of the fuel, the combustion efficiency will be significantly reduced. Strong vortices reduce the radial penetration of the fuel spray as it is injected at the center. As a result, the central area with excess fuel is surrounded by the frivolous force created by the fire. In a four-inch diameter combustion chamber, it is isolated for a tenth of a second. Here, a simple explanation of fuel injection is given in terms of fluid ejection mechanics and illustrates the environmental conditions in which post-combustion buoyancy assists fuel air mixing.
