Spring 2014 will signify the introduction of Volvo trucks powered by a 16-litre Euro 6 engine, and the availability of the company's 13-litre engine with the I-Torque driveline.
The company says that these units will sit alongside the company's existing Euro 6 diesel engines – the smallest being the medium-duty 5-litre power plant and the largest the heavy-duty 13-litre variant.
"Total fuel economy is very important and we have a combination of technology and service offerings that will be difficult for our competitors to match," insists Astrid Drewsen, product manager for drivelines, Volvo Trucks.
For Volvo's heavy-duty engines, the D11, D13 and upcoming D16, Volvo Trucks has retained SCR (selective catalytic reduction) as central to its Euro 6 engine-out emissions after treatment.
The manufacturer says it has now improved the catalytic coating of its SCR unit, while also making improvements to the AdBlue injection system.
Completing the picture, Volvo is 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. Meanwhile, the emissions-busting technology for its D5 and D8 engines is a combination of conventional cooled EGR, particulate filter and SCR.
"Our experience from emissions legislation the world over provided the input for our choice of fuel-efficient, cost-effective and less complex engine technology," adds Drewsen.
In September 2012, Volvo Trucks started selling its first Euro-6 engine – a D13 unit capable of 460bhp. In June 2013, sales of its new D5, D8, D11 and D13 engines will begin, before the arrival of the 16-litre Euro 6 engine in 2014.
