Vane number and swirl angle of a swirler, premixing distance, air velocity and fuel injection methods, etc, have remarkable effects on air-fuel mixture uniformity. 旋流器的叶片数和旋流角、预混管长度、气流速度、喷油方式等对油气混合均匀性均有比较显著的影响;
According to detonation mechanism of single event fuel air explosive ( FAE), the microcosmic structure in the solid and liquid fuel mixture is described and analyzed by fractal theory in this paper. 根据一次引爆燃料空气炸药爆轰的物理机制,利用分形几何原理,描述和分析固液混合燃料介质内部细观结构,探索各组分在起爆过程中的相互关系。
Air and fuel are drawn into the cylinder by the downward movement of the piston, the piston then moves up and squeezes this mixture which is then ignited. 空气和燃料,是由各该活塞向下运动,活塞然后移动起来,这是挤出,然后点燃混合气进入气缸。
The atomization angle, which affects the air and fuel mixture, combustion and emission of engine, can be measured by digital image processing with concentration fields measurement system. 喷油雾化角影响油气混合、缸内燃烧和发动机排放性能.借助浓度场测量和数字图像处理系统对喷油雾化角测量进行了研究;
Relative to CIDI engines, HCCI engines have extraordinarily lower emissions of PM and NOx and can offer more power as high as CIDI engines with the dilute homogeneous air and fuel mixture. 与直喷柴油机相比,HCCI发动机的碳烟和氮氧化物排放非常低,并且稀薄空燃混合气可以产生与柴油机一样高的功率。
It is also found that the air fuel mixture is richer near the combustion chamber wall and becomes leaner gradually from the wall to the combustion chamber center, the stratification concentration from rich to lean of air fuel mixture forms along the direction of air swirl motion. 靠近壁面处燃油浓度最大,向燃烧室中心方向浓度逐渐降低,沿周向、顺涡流方向形成了明显的由浓到稀的分层。
Intake system of piston UAV ( unmanned aerial vehicle) engine is like the artery of heart, providing clean air and fuel for the engine. The mixture of oil and gas is finished in this region. 活塞式无人机发动机进气系统是发动机的动脉,为发动机提供燃烧做功所需的清洁空气和燃料,并且油气的混合也是在此完成。
