Long - hole and geometrical proportion type of mixing unit is finally adapted in lpg supply system, and power and torque output of lpg engine are improved by increasing compression ratio, and ignition characteristic is tried to adjusted to satisfy engine performance. meantime emission performance and noise level of lpg engine at full - throttle and other various part - throttle operations are tested and compared with former gasoline engine. ( 3 ) it is verified by engine dyno tests that lpg engine has better synthesized performance at aspects of power and torque, fuel economy, as well as emission than former gasoline engine

In the process of work, according to complex geological conditions such as huge thick soft clay in site and top surface of possible pile foundation supporting course fluctuating in large amplitude, we adopted many advanced exploratory methods ( just as high accuracy exploration of shallow earthquake, crosshole wave velocity test, vane shear test, pressuremeter test, etc. ), we found out that there is an ancient groove of yangzi river in former plant site, therefore we suggested in time that plant site should properly be moved eastwardly, only this item saved nearly about 50 million for pile foundation project cost
在工作過程,根據廠址區軟粘土厚度大、可能作為樁基持力層頂面起伏變化大等復雜地質條件,採取了多種先進的勘探手段(如高精度淺層地震勘探、跨
