Recently, Scania's Group vice president Research and Development Hasse Johansson announced that Scania will start introducing its new engine platform for Euro 5 during 2007. On these new engines, Scania uses exhaust gas recirculation, without any aftertreatment to meet Euro 5. This technology does not require the driver/operator to handle any additives when refuelling and no extra installations are needed on the vehicle.

"Scania has a leading position in the industry in terms of meeting environmental demands and customer requirements," stated Hasse Johansson. "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. The new engines meet Euro 5 without any fuel penalty," concluded Mr. Johansson.

Two years ago, as the first heavy truck manufacturer on the market, Scania introduced its first Euro 4 engines using EGR technology.

Scania has since introduced a comprehensive range of Euro 4 and Euro 5 engines using both exhaust gas recirculation and selective catalytic reduction1.

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.

1 EGR recycles exhaust gases into the engine to reduce NOx emissions. Scania's high-pressure fuel injection system is used to reduce particulates.

SCR is an after treatment technology that cleans exhaust gases after combustion by injecting a urea solution into the exhaust gases. This system is currently used in order to achieve Euro 5 standards.
