On the basis of an EFI system developed by ourselves, the simulation model of the initial control data and engine operation points during a driving cycle and the car performance pridiction model were established. This method was applied to a mini car. The experiment showed that the simulated control data has good accuracy; and the engine test points and car performances obtained by simulation are useful for the matching of EFI system with gasoline engine and the development speed is increased.展开更多

On the basis of the existing equipment, the throughput of this unit has been increased to 800 kt/a from 500 kt/a, with the total liquid yield reaching 88.66%. In the meantime, the revamp has reduced the pressure drop in the regenerator system with apparent energy conservation effects and significant economic benefits.展开更多

This technique has brought about obvious economic and environmental benefts, which can provide a mate-rial basis to bridge the demand gap in jet fuel supply at the new Beijing Airport and will serve as a good ex-ample of SINOPEC’s efforts in the area of transforma-tion of production mode, structure adjustment, product quality upgrading and enhancement of economic ben-efts at the refning enterprise.展开更多
