摘要
通过TY290柴油机进气道石膏模型的稳流模拟试验,对进气运的结构尺寸作了改进,提高了进气道的涡流比和平均流量系数,改善了进气道的品质和TY290柴油机的性能。
A steady-flow simulation test on plaster model inlet port of TY290 diesel engine was carried out. The inlet port dimension was optimized on the basis of the test results. Tbe improvement on swirl ratio and mean flow factor of the inlet port, inlet port quality and the diesel's performance have been realized.
