Why do I need a common rail fuel injector?
Fuel injectors, although small in size, play an extremely important role in the way your engine performs. Common rail fuel injectors are the most widely used type of injectors in diesel engine trucks. If you’ve noticed a drop in performance, heavy smoke, misfires, etc., it could be that your common rail fuel injectors are the ones to blame.
What kind of fuel injector do diesel engines use?
Common rail fuel injectors are the most widely used type of injectors in diesel engine trucks. If you’ve noticed a drop in performance, heavy smoke, misfires, etc., it could be that your common rail fuel injectors are the ones to blame.
Where is the fuel injector and fuel return Line located?
The fuel supply line is connected to the fuel damper and the fuel return line is connected to the fuel pressure regulator. On ’85 model and older cars, the fuel damper and fuel pressure are located next to each other near the back of the fuel rail.
Why are my fuel injectors not working properly?
Take away the fuel rail from the intake manifold, lifting the injectors with it. You will use a little pressure or a good amount of force here. The reason is that the injectors are joined to the rail, and the sprayer tips are a tight fit in the intake manifold.
How do you install fuel injectors?
Install the new fuel injectors into the fuel pipe by twisting them into place so that the electrical connectors face away from the fuel pipe. Coat the injector bores in the cylinder head with light machine oil. Install the spacers and connect the fuel pipe to the cylinder heads.
What is the most common fuel injection system?
As technology advances, direct injection engines may become easier to manufacture, but, for now, sequential multi-port injection remains the most common fuel injection system in cars today. It provides the right mix of efficiency and affordability for most applications.
How does common rail injection work?
The common rail-fuel-injectors are controlled by the vehicle’s Engine Control Unit. When the injectors are activated by the ECU via a signal, a hydraulic valve made up of a plunger or nozzle, either hydraulically or mechanically, opens and sends fuel into the engine cylinders.
What is common rail direct injection?
Common rail. Common-rail direct fuel injection is a direct fuel injection system for diesel engines. On diesel engines, it features a high-pressure (over 100 bar or 10 MPa or 1,500 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
