Taking the lead in environmental technology
Scania has decided, in line with its environmental policy, to offer low-emission engines to the market well ahead of legal requirements. Scania’s low-emission engines cut emissions of nitrogen oxides, hydrocarbons and particulates by around one-third. Thanks to engineering advances, fuel consumption and carbon dioxide emissions are unaffected in normal driving.
"Environmental leadership is one of Scania's core activities. We not only take on responsibilities ourselves to reduce pollution, we also enable all Scania operators to do the same," says Lars Orehall, Senior Vice President Powertrain at Scania.
"Controlling emissions always involves a trade-off between NOx and fuel consumption. But engine development progresses all the time. By boosting torque at low revs we have improved driveability.
"The low-emission engines provide similar performance to their Euro 2 counterparts, but at lower engine speeds. Driven correctly, they will also have similar fuel consumption.
"The best way of safeguarding economy while keeping down emissions is to specify Opticruise, Scania's automated gearchanging system. This system is perfectly matched to the character of the new engines," explains Mr. Orehall.
Fitting a particulate trap (CRT) will cut emissions further without impairing performance or operational economy. This equipment can now be fitted to Scania's 9-litre engines for urban applications.
Maintenance intervals in the 40-tonne long-haulage have been doubled - up to 120,000 km depending on the type of operation. The intervals are determined jointly by the operator and the Scania dealer. The use of oils and other lubricants has thus been cut by up to 45%, reducing maintenance costs and environmental impact.
Intelligent Transport Services (ITS) are set to expand dramatically in the next few years. Scania now offers (from February 2000) a communication interface that facilitates data transfer from the truck. Scania's solution aims at long-term flexibility, facilitating the use of various peripheral systems that can use the standardised information from the truck’s data bus.
ITS systems are used for example to navigate or to track the vehicle, for route and logistics planning, fleet management and to provide on-board communication based on wireless web technology. Better logistics and fewer empty runs will help reduce the environmental impact of transportation.
Smarter use of materials constantly enables Scania to reduce the environmental impact from production, while enhancing on-road productivity and facilitating recycling. The latest improvements involve cab panels that save up to 60 kg on a complete cab and a lighter double-drive bogie.
