| 摘 要： | 对TBD620柴油机进气系统进行了理论和试验研究。缸头气道稳流试验数据表明该机在低负荷工况下,在进气量较小时,采用单独涡流气道进气和直流气道不完全封闭,可以获得较大的进气涡流,达到改善大功率柴油机低负荷性能的目的。

| Abstract: | The theoretical and experimental study on intake system is given for TBD620 diesel engine. A great deal dataobtaining from the stead flow test of the cylinder head intake port illustrated that the preferable intake swirl can be obtainedand low load performance of the heavy-duty diesel engine is improved only adopting the single swirl intake port and thedirect intake port incompletely closed, when the TBD620 diesel engine working in the low load condition and less charge. |
