摘要
国产汽油机的比油耗普遍较高的原因是在化油器设计、制造、调试和使用中混合气变浓使进缸混合气的空燃比变小，造成燃烧不完全． 试验研究表明采用二次补偿空气， 可有效提高进缸混合气的空燃比，
The mainly reason the specific fuel consumption of gasoline engines is higher is that, in the design, manufacture, regulation and utilization, the thickening of mixed gas makes the air_fuel ratio decrease only to result in inperfect burning. The experimental research shows that the adoption of secondary compensation air can improve the air_fuel ratio of the mixed gas in the cylinder..
