摘　　要：以角动量合成理论为基本依据 ,以内置式稳态滚流测量装置测量所得的滚流试验数据和稳态涡流试验数据为源数据 ,推导了缸内斜轴涡流特性参数的计算公式 ;并利用这些公式计算了 CA1 1 0 2发动机两种缸盖的斜轴涡流特性。结果表明 ,进气门后方具有较大挤气区域的缸盖具有较强的产生缸内斜轴涡流运动的能力 ,同时也具有较稳定的斜轴涡流形态。分析表明 。According to the angular momentum synthesizing theory,the calculating formulas of characteristic parameters of inclined swirl were developed from the steady tumble data from laid in tumble measuring device and steady swirl data.Inclined swirls of two cylinder heads of CA1102 engine were computed with these formulas.The results indicate that the cylinder head with larger squash area can produce stronger inclined swirl and the outline shape of inclined swirl is steadier.The analysis shows that the results are from channeling effect of squash area behind intake valve on intake flow.
