All Scania engines are turbocharged and charge-cooled. The role of the turbocharger is to give a boost to efficiency, rather than outright extra power. An important feature of the Scania turbo is its ability to give an effective boost even at very low revs, creating the conditions needed for a rapid build-up of torque as engine speed rises just 400-500 revs over idling speed.
Economy: The turbo is effective at building high levels of torque at low revs, and maintaining the torque over a wide range of engine speeds. High torque at low revs is beneficial for fuel economy. Low emissions: The effectiveness of the turbocharger right across the rev range is a key factor for driveability and economy of the engine, both of which help keep down emissions. Back
