Ford F-550 Super Duty Fuel Injectors /h2>

A fuel injector is the component responsible for providing fuel to an internal combustion engine. All diesel vehicles use them, and they are also used by some gasoline-powered vehicles for a smoother throttle response, easy starting during cold temperatures, good gas efficiency, and stable idling. When looking for replacement parts for your diesel, consider the types and features you prefer before purchasing.

• Rotary injection pumps: These types of pumps will use a single fuel-metering plunger, which makes them smaller than other injection systems. This type of injector also ensures that all shots of gasoline are exactly the same volume and delivers up to 17,000 psi of pressure.
• Inline-injection (jerk) pumps: These pumps will use plungers to force gasoline into the combustion chamber. They are installed on each cylinder individually and are activated by a camshaft located on top of the pump. A few jerk pump models deliver up to 18,000 psi of pressure.
• Unit injection: This compact injection system in your pickup uses a pump plunger in order to create a high level of pressure within the motor. Then the pump and plunger work together to deliver gasoline to the combustion chamber for high gasoline efficiency. These injectors are most common in large diesel vehicles.
• Common-rail injection: This is the least common type, since the pump does not work in the same way as the others mentioned above. Instead of the pump deciding the pressure, it instead receives gasoline from the tank and then uses a radial-piston design to create large amounts of pressure. The highly pressurized gasoline then enters the common-rail for the combustion process.

• Fuel atomization: It is this process that allows the gasoline to atomize into small particles that are easier to break down in the combustion process. It is important in diesel engines and large vehicles with higher levels of vehicular drag.
• Bulk mixing: This process comes after atomization. It will ensure that the gasoline has sufficient oxygen levels provided by the intake manifold during combustion. With this step, the oxygen in the fuel will be equally distributed and able to be fully utilized.
• Air utilization: This feature happens after bulk mixing. It ensures that enough oxygen has been forced into oxygen-deprived areas of the cylinders, valves, and jets for optimum efficiency.
