Volvo Trucks introduces Euro 6 engines

Volvo Trucks has introduced new trucks with Euro 6 compliant engines ranging from the smallest medium-duty 5-liter engine to the heavy-duty 13-liter variant. Starting in spring 2014, Volvo trucks will also be available with a 16-liter Euro 6 engine and with the I-Torque driveline for the 13-liter engine.

For the heavy-duty engine range, the D11, D13 and the upcoming D16, Volvo Trucks has retained its SCR (Selective Catalytic Reduction) technology. SCR has proved to be extremely effective in the after-treatment of emissions and it is also the ideal match for Euro 6 requirements, the company says. In addition, Volvo Trucks has improved the catalytic coating of its SCR unit and the AdBlue injection system.

In order to comply with Euro 6, the heat in the exhaust system must be kept at a more or less constant high level. Volvo Trucks is therefore combining its SCR solution with non-cooled EGR (Exhaust Gas Recirculation) and a diesel particulate filter (DPF) in its D11 and D13 Euro 6 engines. The technological solution for the D5 and D8 engines is a combination of cooled EGR system, particulate filter and SCR.

In September 2012 Volvo Trucks started selling its first Euro 6 engine, a D13 unit with 460 horsepower.
