The Sprinter 2500 doesnt have a supercharger. It does have a turbocharger though.

The basic idea is that the exhaust drives the turbine (the red fan), which is directly connected to (and powers) the compressor (the blue fan), which rams air into the engine. For simplicity, we're showing only one cylinder. Here then, in summary, is how the whole thing works:

  1. Cool air enters the engine's air intake and heads toward the compressor.
  2. The compressor fan helps to suck air in.
  3. The compressor squeezes and heats up the incoming air and blows it out again.
  4. Hot, compressed air from the compressor passes through the heat exchanger, which cools it down.
  5. Cooled, compressed air enters the cylinder's air intake. The extra oxygen helps to burn fuel in the cylinder at a faster rate.
  6. Since the cylinder burns more fuel, it produces energy more quickly and can send more power to the wheels via the piston, shafts, and gears.
  7. Waste gas from the cylinder exits through the exhaust outlet.
  8. The hot exhaust gases blowing past the turbine fan make it rotate at high speed.
  9. The spinning turbine is mounted on the same shaft as the compressor (shown here as a pale orange line). So, as the turbine spins, the compressor spins too.
  10. The exhaust gas leaves the car, wasting less energy than it would otherwise.

See attached diagram for the above reference steps in how a turbo works.

Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.
Expert:  sprinkles08 replied 7 months ago.
White fuel smoke is caused by cold combustion due to excessive fuel being injected. The problem is almost surely one or more worn injectors. A cylinder contribution test as well as an injector kill test will need to be done with a scan tool to isolate the offending cylinders.
Customer: replied 7 months ago.
I already replaced all 6 injector
Expert:  sprinkles08 replied 7 months ago.
That information was not previously posted.What was the part number of the injectors installed?What testing was done to determine they needed to be replaced?Is there any other necessary information that was omitted?
