Scania launches low-emission engines for city environments
Scania launches a new engine with low emissions of all regulated substances. Emission levels are down for NOx and for particulates. Starting in buses from October 1998, the new engine will be offered in trucks during 1999.
"We notice that in several European countries, environmental performance is rapidly becoming a competitive issue for our customers," explains Leif Östling, Scania's President and CEO. "The strongest interest is coming from our customers’ customers, who want their transportation to be undertaken with as little harm to the environment as possible. By introducing the option of lower emissions we enable operators to make their own choice."
The new engine is a revised version of Scania's 9-litre unit, featuring EDC (electronic diesel control). With a power rating of 230 hp and maximum torque of 1,100 Nm between 1,100 and 1,200 r/min, the new engine is suitable for urban operation. This unit is initially available for urban buses, mounted transversely at the rear. During 1999, Scania will launch low-emission engines for other applications as well, including road haulage. The introduction will take place selectively, in pace with market demands.
Compared to its 220-hp 9-litre stablemate, emissions of nitrogen oxides have been reduced by 20 percent and particulate matter by 30 percent. Specific fuel consumption is up from 196 g/kWh to 205 g/kWh, but lower emissions and good driveability are generally more important than ultimate fuel economy in this type of operation.
"There is generally a trade-off between exhaust emissions and fuel consumption," says Håkan Samuelsson, Executive Vice President and Scania's Chief Technical Officer. "By continued development of the diesel engine we have managed to keep this trade-off within reasonable bounds.
"In the future, the technology level of individual engines will be a significant parameter for emission compliance. We regard electronic engine management as a prerequisite for good performance and driveability," concludes Mr. Samuelsson.
