Power Train and is in charge of Iveco's long-established engine research centre in Switzerland. It's fair to say he is impressed with Scania's progress. However, he believes that an EGR-only approach puts the engine cooling system under strain.
"We've looked at the solution of course: two liquid cooling circuits, one for the engine, one for the EGR system," Ellensohn reports. "At least under the Stralis cab there's sufficient space to do this."
Ellensoh n, who is also the architect of lveco's Cursor engine family, confirms the need for extra cooling capacity. He expects that engines cleaned via EGR will need to grow in size even more than they have done so far. But the company has no plans to develop engines running slower than 1,000rpm."That's what the market wants," he assures us.
And he rams the message home that the ball is in the legisators' court:"1 and my colleagues from other manufacturers really need to be told by the legislators what Euro-6 will be about.The same goes for CO2 and alternative fuels. As long as nothing is defined, we can't proceed in our investigations to create a cleaner future for road transport."
