With Euro-6 looming on the horizon, the major manufacturers are looking at a range of technologies to clean up their act. Tim
de Jong caught up with their boffins at RAI.
Last year, Iveco and MAN launched new trucks. It was obvious that both vehicles had more air inlets in the front of the cab than before there were even holes in the front bumpers to let fresh air pass through. But why?
At the RA! Show in Amsterdam, CM spoke to a number of engine designers about the next stage in the Euro emissions standards, Euro-6. To date none of these specialists knows the details of Euro-6, but it is expected to end the EGR vs SCR debate, simply because both systems will be needed to meet the standard.
Professor Karl Victor Schaller of MAN summed up the industry view: "Nobody will be able to meet Euro-6 with EGR only unless you accept a 15% fuel penalty."
No fuel penalty
But not everyone agrees with him.Scania, for L'.xample,has managed to meet Euro-5 with EGR only and, it claims, without incurring a fuel penalty. And the Swedes do not rule out being able to crack Euro-6 with EGR only.
Engine development manager Jonas Hofstedt said:-We will never accept any fuel penalty before we bring a new EGR solution :o the market. lean assure you that."
