摘要：

利用超声雾化多液滴制备系统,制成了柴油/汽油混合燃料多液滴群,其中液滴直径、液滴浓度、液滴速度等参数均可独立调节,以模拟内燃机缸内喷雾的实际流动及其与空气的混合状态。将该多液滴群引入可控活化热氛围燃烧器中,并对其稳定燃烧后的燃烧特性进行了研究。结果表明:改变混合燃料掺混比、燃料进给速度、空气流量等参数后,多液滴群自燃火焰形状随之发生显著改变,随着燃料中柴油所占比例的增大,火焰起升高度增加,火焰宽度减小;燃料进给速度和空气流量的改变,影响了混合燃料的燃空当量比及中央射流出口速度,进而影响到燃料的燃烧特性。

Abstract:

Droplet swarm of diesel-gasoline blend fuel is prepared on an experimental system based on ultrasonic atomization technology. The mean droplet diameter, air/fuel ratio and droplet speed are independently adjustable to simulate the flow and mixing conditions of the spray in the cylinders of internal combustion engine. The droplet swarm is imported into a Controllable Active Thermo-Atmosphere Combustor (CATAC) to investigate the steady combustion characteristics of the droplet swarm. Results show that changing the diesel-to-gasoline mixing ratio, the fuel feeding speed and air flow leads the shape of spontaneous flame changes significantly. As the diesel component increases in the blend fuel, the lift-off height of flame increases, while the width of the flame decreases. The variations of fuel feed speed and air flow influence the equivalence fuel-to-air ratio and the central jet velocity, thus greatly influencing the fuel combustion characteristics.

Key words: power machinery and engineering, ultrasonic atomization, diesel-gasoline, blend fuel, combustion characteristics
