The latest model of the Cummins QSK19R has been modifed with a new very high pressure common rail injection system (Note 1) specficly to meet the latest European emission standards even at 750BHP output.I just think dropping from 750hp to 650hp is more trouble than it is worth. Are we really going save that much in fuel by dropping 100hp per car?I'm guessing PTV V/Line had their arm twisted to have their new diesel powered machines to comply with the latest (local) diesel emission standards (Euro 2)
Note 1: such an injection system makes the engine burn cleaner and quieter. Common rail means all injectors are supplied with VERY high pressure fuel via a common pipe and the injectors are totally controled electriclly. It means the combustion process can be much better controled. Its a great system as long as you do not have to get it fixed which is VERY expensive. THe only test rig in Australia is at Bosch in Melbourne.
