摘　　要：试验比较了两种适合FAI二冲程缸内直喷发动机的燃烧室——半球形和斜锥形燃烧室。研究结果表明,在低速低负荷工况下,斜锥形燃烧室较为适合,HC排放和燃油消耗改善较好。Two combustion chambers adapted to FAI two-stroke GDI engine are tested and researched, which are the inclined-tapered chamber and the hemispheric chamber. Results of dynamometer tests demonstrate that the inclined-tapered chamber is more appropriate to obtain better emission and fuel consumption during light load operations.
