How is the injector current on a diesel engine controlled?
How is the injector current on a diesel engine controlled?
Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select Injector current. Further guidance. A common rail diesel injector delivers atomised fuel directly to the combustion chamber. Injection timing and quantity is controlled by the Engine Control Module (ECM).
What happens if solenoid injector is not properly sealed?
Cylinder sealing: if the interface between the injector and the cylinder head is not properly sealed, unburnt or partially burnt gasses and soot can escape from the cylinder during compression and combustion, causing blow-by and reduced cylinder pressures/combustion temperatures, which, in turn, can cause excessive exhaust smoke.
What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
Where are the unit injectors located in an engine?
Unit injectors are installed directly into the cylinder head above each combustion chamber. The injector is driven by the engine camshaft, most often directly through only a rocker lever as in the case of an overhead camshaft.
Can a fuel injector not receive the correct voltage?
It is possible for the injector to cause issues even if it is receiving the correct voltage. They can clog up, which will decrease the spray inside the cylinder. This, in turn, causes the fuel to not burn completely and will create a misfire.

How is an injector related to an electric field?
An injector is a coil, from an electrical point of view. A coil that has a voltage applied to it and then when you turn it off, it fights to sustain its electric field. It wants to retain that charge and as the field collapses, it generates a fairly large very fast pulse of the opposite polarity (a phenomena called “Back EMF”).
What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.
