Dodge Fuel Injector
The Dodge fuel injector is an electronically-controlled
valve that supplies pressurized fuel into your vehicle’s engine and is
capable of opening and closing many times per second. When it is
energized, an electromagnet moves a plunger that will open the valve
and allow the pressurized fuel to be sprayed through a tiny nozzle.
This nozzle is designed to atomize the fuel to make a fine mist for
easy combustion. The amount of fuel supplied is determined by the
amount of time the fuel injector stays open. This is called the pulse
width and is controlled by the ECU. The part is usually mounted in the
intake manifold so that it sprays fuel directly into the intake bulbs.
Though the functional objectives of the
fuel injectors may vary, they all share a central task, which is to
supply fuel for the combustion process. The Dodge fuel injector has
several competing objectives: better power output, fuel efficiency,
tight emission performance, the ability to accommodate alternative
fuels, drivability and smoother operation, initial cost, maintenance
cost, diagnostic capability, and the range of environmental operation.
For the gasoline engines, the carburetors
were the predominant method to meter the fuel prior to the widespread
use of the electronic fuel injection. One major distinction between the
carburetors and the fuel injectors is that the fuel injector atomizes
the fuel by forcibly pumping it through a small nozzle under high
pressure. On the other hand, the carburetor relies on the vacuum
created by the intake air rushing through it to add the fuel to the air
stream. With the tightening of regulations, the fuel injectors overtook
the carburetors in terms of popularity among automakers.
The fuel injector performs one vital
function to combustion. When it fails, you must get a new Dodge fuel
injector to keep your fuel supply in optimum level.
