摘　　要：简述了可调进气涡流的意义及实现方式;针对1150G柴油机采用的双短直气道进行了诱导进气涡流的研究,利用设计的同向、反向双蝶阀诱导涡流方案,开展了非增压和增压条件下的对比试验研究。试验结果表明,可调进气涡流可使发动机全工况下的性能大为改善,在低速低负荷时,在不同功率下燃油消耗率降幅明显,是改善燃油经济性的有效方法。The development situations of variable intake swirl technology for diesel engine are reviewed in this paper. Two type of double butterfly valve were designed by authors to induce and adjust intake swirl in 1150G diesel engine with non-swirl inlet ports. The comparative experiments had been carried out at natural aspiration and high boost pressure. The experimental results showed that variable intake swirl could reduce specific fuel consumption,specially at low speed and load conditions.
