Scania's head of research and development Hasse Johansson has announced that the truck maker will start introducing its new Euro 5 engine platform next year.

On these new engines, Scania uses EGR, or exhaust gas recirculation, without any aftertreatment to meet the Euro 5 emissions rules.

This technology does not require the driver/operator to handle any additives when refuelling and no extra installations are needed on the vehicle.

"During 2007 Scania will start introducing a new range of Euro 5 engines with EGR and with the new Scania XPI common-rail fuel injection system, starting in the mainstream long-haulage segment," Johansson said, adding that the new engines meet Euro 5 without any fuel penalty.

Scania was the first heavy truck maker to introduce Euro 4 engines using EGR technology two years ago.

It has since introduced a comprehensive range of Euro 4 and Euro 5 engines using both EGR and SCR2 (selective catalytic reduction).

Experience of Euro 4 and Euro 5 in day-to-day operation indicates that truck and bus operators prefer EGR because this technology is more convenient for many applications.
