Heavy-duty vehicle facility

 

​​With high fuel prices, fuel economy is extremely important. Public authorities, bus fleet operators and transport companies need comparable emissions and fuel consumption figures to be used in vehicle procurement. However, such data does not exist, because in heavy-duty vehicles, including buses, certification is done by using stand-alone engines and fuel use or CO2 emissions are not even measured.

Our chassis-dynamometer facility for heavy-duty vehicles enables us to determine emissions and energy use from complete heavy vehicles using real-life transient-type duty-cycles. The possibility to work with complete vehicles and accurately simulate real-life duty-cycles opens up excellent possibilities to determine specific emissions and energy use simulating realistic, in-use conditions.

R&D on emission control devices and assessment of means to reduce energy use are also more comprehensive, when the complete vehicle can me taken into account.

Running tests with complete vehicles is more cost-effective than testing stand-alone engines, especially if in-use vehicles are involved.
