| 摘要: |
| 研制了一种向螺旋进气道入口喷射空气的可变涡流进气系统－控制涡流型可变涡流进气系统，试验研究了该系统对直喷式柴油机排放性能的影响。结果表明，该系统在不影响进气充量的情况下，可以明显减少直喷式柴油机排气中微粒的质量浓度和氮氧化物的排放量。 |

| Abstract: |
| The variable swirl intake system with subsidiary swirl contr ol by means of air injection in the helical intake passage was developed, and the influence of the system to the exhaust performance of D.I. diesel engine was stu died. The test results showed that this system is able to make obviously change to the particulate and NO x emission without obvious increase of volumetric efficiency. |
