    haft. The spring between top cover and distributing valve is used for enforcing sealability. The two gears synchronous to crankshaft moving transmit rotation number into pulse sensor. Working principle This type measurement transducer is similar to a set of hydraulic motor, which is driven by pressured oil. Thus, the discharge is corresponded to the crankshaft rotation. As distributing valve’s position is certain when oil flowing into measurement transducer, the piston discharge or inflow also is constant. Pistons depend upon the different oil pressure of inflow and discharge to move, which form a shuttle movement. The above two pistons movements create a third cylinder, which also has a 120 degree angle. The dynamic working circulation is showed in Diagram 2-25. As the diameter and moving distance of piston is certain, the relation between movement and crankshaft rotation also fixed. In every two times inflow or discharge of piston, crankshaft turn around a circle, oil volume in inlet or outlet progress is constant. 1-Piston 2-Crankshaft 3-4-Connecting rod 5-Screw 6-Bearing 7-Bushing 8-Frame 9-Distributing valve 10-Top cover 11-Bearing 12-Spring 13-14-Gear 15-Adjusting bolt 16 fuel dispenser -T-shaped key 17-Sider cover Diagram 2-24: Structural drawing of four-piston measurement transducer Diagram 2-25: Working principal drawing This type of measurement transducer includes 1L circulation discharge and 0.5 L circulation discharge,selecting according to wanted discharge of fuel dispenser. Discharge adjustment Over a long period of operation the accuracy of measurement transducer declined due to either parts abrasion or large change in oil temperature and viscosity. Therefore, regulative device often used to adjust the accuracy within the stipulated scope of national metrology appraisal. The following procedure is conducted as measurement accuracy decline.

    ment. Earlier this year he and Mr Bingaman published a white paper on how a trading scheme might work. So on Capitol Hill the issue is not dead but resting. Three things might wake it up first, a strong performance by Democrats in the mid-term elections; second, and more important, a new president. The favourites for the two parties nominations, Mr McCain and Hillary Clinton, both favour mandatory federal emissions controls. Third, the Supreme Court is to rule next year on whether the federal government has the right to control carbon-dioxide emissions under the Clean Air Act. That will either pave the way for legislation or kill off the possibility. © 2006 . About sponsorship Where to start Sep 7th 2006 From The Economist print edition AP Green Bush Technological and economic solutions to climate change are available. The problem is politics THE sheer number of scientists, economists, businesspeople and policymakers working on climate change endows it with a k fuel dispenser ind of blitz spirit. Surely, given so much will and enthusiasm, we can defeat this threat? Yet the projections are not encouraging. The concentration of CO2 in the air has risen from 280ppm before the industrial revolution to around 380ppm now, and the IPCC reckons that if emissions continue to grow at their current rate, by 2100 this will have risen to around 800ppm. Depending on population changes, economic growth and political will, this could be adjusted to somewhere between 540ppm and 970ppm. The prospect of anything much above 550ppm makes scientists nervous. In order to control these figures, it is important to pick some priorities. The sources of this problem range from smokestacks through Amazon fuel dispenser ian deforestation to pig effluent; from Mexico to Mauritania.
