I know the burner uses a CAV (combustion air valve) to turn air on and off to enter the burner. Where does that air come from? I thought it came from the air tank (for air brakes). But I read in another post that it comes from the turbo.
Does the air get injected through the atomizer nozzle or is there some other orifice in the burner?
When does it inject air and what is the purpose? I saw a video that said it injects air through the atomizer nozzle after it sprays fuel to clean out the nozzle. And then I read elsewhere that the air is introduced because is needed to ignite the fuel.
