Volvo Trucks to field test 2010 emission vehicles

Volvo Trucks North America has delivered five Volvo trucks that meet the US10 truck emission standards to customer for field testing, according to Volvo information.

The US10 standard becomes effective in 2010. The trucks were delivered to Talon Logistics, which will test the selective catalytic reduction technology that is common in Europe. To date, the emission requirements in North America were met by applying exhaust gas recirculation technology and particle filters.

SCR is a method for reducing the amount of nitrous oxides in diesel exhaust emissions. The method involves spraying a mixture of urea and water, so-called AdBlue, into the exhaust gases. Heat from the exhaust gases converts the urea to ammonia that reacts with the nitrous oxides in a catalytic converter, in which they are transformed into nitrogen gas and steam, Volvo said.
