of the control valve member away from the first valve seating only causes movement of the valve needle into a first fuel injecting position and movement of the control valve member away from both the first and second valve seatings causes movement of the valve needle into a second fuel injecting position.
The valve needle may include first and second fuel outlet passages axially spaced on the valve needle such that, when the valve needle is in the first fuel injecting position, fuel is only discharged through the first outlet passage and, when the valve needle is in the second fuel injecting position, fuel is also discharged through the second outlet passage. In this way, the rate of fuel injection into the engine can be carefully controlled.
Conveniently, the fuelconservationists in the U.S., Singapore, Netherlands and Malaysia.

"In most parks, ranger patrols are poorly planned, reactive rather than pro-active, and habitual," according to Fei Fang, a Ph.D. candidate in the computer science department at the University of Southern California (USC).

Fang is part of an NSF-funded team at USC led by Milind Tambe, professor of computer science and industrial and systems engineering and director of the Teamcore Research Group on Agents and Multiagent Systems.

Their research builds on the idea of "green security games" -- the application of game theory to wildlife protection. Game theory uses mathematical and computer models of conflict and cooperation between rational decision-makers to predict the behavior of adversaries and plan optimal approaches for containment. The Coast Guard and Transportation Security Administration have used similar methods
