Injector

Refers to the pump system (used in a fuel injection system) that squirts or injects a measured amount of gasoline into the intake manifold in the vicinity of the intake valve. In the diesel engine fuel is injected directly into the cylinder. In a Continuous Injection System (CIS), the injectors atomize the continuous flow of fuel injected under pressure into the intake ports of the engine; a valve in the injector nozzle stops the flow of fuel when fuel pressure drops below a certain point; in a CIS, the quantity of fuel is regulated by the fuel distributor's metering unit; in other fuel injection systems, the fuel system delivers a constant supply of fuel at a constant pressure to the injector, and an electronic sensing and control system produces electrical current pulses of appropriate duration to hold open the injector solenoid valves; as fuel pressure is held constant, varying the pulse duration increases or decreases the amount of fuel passed through the injectors.

For instance, in Maine, motorists under the age of 18 aren’t allowed to have any passengers with them as they drive for the first 180 days after they obtain their licenses. In Alabama, motorists under the age of 18 can have one passenger with them.

And that’s just one example of the differences in driving license requirements from one part of the country to the next. The differences are even more pronounced when comparing one country to another. Minimum driving ages vary widely across the world. While most states in the United States allow youngsters to earn their learner’s permits at the age of 15, many other countries require their residents to be much older before they get behind the wheel of a car.
