采用LaVision公司特色的以DaVis软件平台为基础构成的粒子成像测速(PIV)系统对气缸内流动结构在一段大范围的实际发动机转速区间内的速度场进行了测量和分析。
In-cylinder PIV measurements have been made during the latter half of the intake stroke on a
plane between the inlet valves for a single cylinder optical engine operating at engine speeds of 750, 2000
and 3500 rpm. Mean vector fields for an area of 42 mm by 34 mm have been produced with vectors at
approximately 1 mm resolution. The vector fields show the development of the flow field in 1.6°, 2.4° and
3.2° steps for the three respective engine speeds.
Tumble ratios have been calculated from these vector fields which show that a change in the flow regime
occurs between 2000 and 3500 rpm. This is caused by one of rotating vortices becoming detached from the
descending piston at the highest engine speed.
