小型二冲程发动机气缸体静态扫气试验台的研制

R & D of Static Scavenging Test Rig for Small 2-stroke Engine Cylinder Block

通过 EGJS-1型二冲程发动机气缸体静态稳流扫气试验台,将测取的压力值输入微机,把相同的压力点连接起来绘制出每一个气口开度下的扫气图,同时计算出“时均流量”和“时均流速”,由此来评价扫气性能的优劣。

By means of EGJS-1 model static steady-flow scavenging test rig for 2-stroke engine cylinder block, input the measured pressure into micro-computer, join all the similar pressure points together to plot the scavenging diagram below the opening of each port and calculate the 'mean flow/hour' and 'mean flow speed/hour' to evaluate the scavenging performance.
