gasoline consumption
2.Test results show that engine oilcontaining 8% FPS type friction-reducer increase gasoline engine efficiency by4.5% and cylinder press pressure by 7.7%,save 3%~6% of fuel constumption and30% of gasoline engine oil consumption,decrease exhaust temperature by 2~17℃,and improve load and speed performance of engine.
4.The test results indicate that the desulfurization and olefin removal of FCC gasoline of OTA are about 60%~77% respectively, road octane number( (R+M)/2) loss is 0~1.2 units, C~+_5 gasoline yield is 92.0%~97.0%, and chemical hydrogen consumption is 0.20%~0.40%.
5.Under the nominal operating condition, the specific fuel consumption of burning the mixed fuel of C5 occupyingquality component as 32. 4 % to 100% is respectively lower than that of burning MON 70 gasoline by 8. 6 %and 9. 6 %.
6.Decreasing emission and fuel consumption of automobile is an international issue about environmental protection and source of energy. To control the transient AFR(air-fuel ratio) of gasoline engine in high precision is an important measure to solve this issue, but it is a difficult and challenging subject which is well known of the world.
