摘　　要：在稳流气道试验台上开展了诱导产生发动机进气涡流和可调进气涡流的研究工作，证明在短直气道内，通过安装进气导流片能够产生一定强度的进气涡流，再配合另一气道进气流量的控制，可获得发动机缸内可调的进气涡流。非增压发动机试验表明在低速低负荷工况下，发动机的燃油消耗率有明显的改善。An investigation on the induced inlet swirl and variable swirl system was conducted on a steady flow test rig.The short and straight port fitted with diversion blades is able to generate the induced inlet swirl,and by control the airflow rate of another port,the variable inlet swirl can be obtained in the engine cylinder.The tentative tests show that the specific fuel consumption is obviously reduced under the partial load operating condition.
