Swedish inboard engine specialist Volvo Penta has further developed its D13 unit to meet EPA Tier 3 regulations – the new marine environmental emission standard.
According to Volvo, the new version of the D13 offers "improved environmental properties with basically unchanged low fuel consumption".
The D13 is a diesel engine that has been developed within the Volvo Group. It is among the world's most proven engines and is currently in operation in more than 450,000 heavy-duty industrial applications, including unique custom marine applications, off-road and electricity generation, and buses, trucks and construction equipment.
Environment performance and fuel efficiency
The full range of Volvo Penta D13 marine engines is now upgraded to meet the requirements of EPA Tier 3, which will take effect from 1 January 2014. EPA Tier 3 involves a 40 per cent reduction in particulate matter in the exhaust gases and a 20 per cent reduction in NOx and hydrocarbons.
These high standards are met by the new D13 with the same power and "basically identical" fuel consumption.
"It is world-class fuel efficiency together with less environmental impact," continued Volvo.
"The upgrading of the environmental characteristics will neither change the performance, nor the fuel efficiency. Nor does it imply any changes in terms of design, size or installation − in these respects will there be no difference to the boat builder, owner or operator."
The Volvo Penta D13 is available as both as a propulsion engine (D13 MH) or as a marine genset (D13 MG) optionally equipped with different cooling systems.
