The US10 standard becomes effective in 2010 and the trucks now delivered are equipped with the EGR (Exhaust Gas Recirculation) and SCR (Selective Catalytic Reduction) emission-control systems. The VN model trucks have been delivered to a customer, which will now field test the SCR technology that is common in Europe. To date, the emission requirements in North America were met by applying EGR technology and particulate filters. The trucks now being delivered are also equipped with SCR.
