Volvo Penta Presents D13 MG Marine Genset Engine (Sweden)

The new Volvo Penta D13 MG marine genset offers more power and high load acceptance, with emission levels in compliance with EPA Tier 3 and low fuel consumption. The secret is the advanced technology Volvo Penta uses throughout the engine.

As with all Volvo Penta marine gensets, the D13 MG is delivered complete with electric generator and onboard electronics, tested and classified.

“The D13 MG is better in every respect, compared to the current D12, which also is a very good engine,” says Gerard Törneman at Volvo Penta. “For the customer the load acceptance and low fuel consumption will mean more efficient operation at a lower total cost.”

Low fuel consumption and Tier 3 emissions

Fuel cost alone is a very high portion of a marine genset life-cycle cost. EMS 2, the engine control system developed by Volvo, regulates fuel injection and monitors engine conditions. The system controls the unit injectors, one per cylinder, which operate at a pressure of as much as 2000 bar and atomize the fuel for optimum combustion. The result of this efficient combustion is low fuel consumption, combined with emissions in compliance with Tier 3.

Choice of cooling system

The D13 is available with keel cooling, heat exchanger or radiator cooling already from the introduction. This means it is ready to use for a number of applications, auxiliary, harbor operations, emergency and diesel electric propulsion.

Reduced noise

The noise level of the new D13 MG has been further reduced thanks to variable injector pressure and a new, efficient cooling system. The harbor and emergency gensets with radiator cooling system can offer even lower sound pressure with an optional visco fan.

Miller timing and twin-entry turbo

The D13 MG has very low levels of NOx emissions and no visible smoke, regardless of load. This is combined with high load acceptance, much thanks to the advanced and efficient charge air system. The D13 MG has a mid-position, twin-entry turbo with waste gate. This turbo offers pulse charging with high charge air pressure directly from low rpm. To fully utilize this efficient turbo, it is combined with Miller inlet valve timing. This means that the inlet valve closes earlier, reducing engine temperature and mechanical stress, which allows for higher boost pressure. Equally important for durability is the cooling system. D13 MG features a plate heat exchanger – a proven and reliable technology. All D13 MG models comply with the EPA Tier 3 emission regulations.

High quality

The D13 MG has the same robust basic architecture as engine platform used for the Volvo D9, D11, and D16 in-line 6 diesel. The platform features a rigid block design, wet liners, rear-end transmission, ladder frame and a single cylinder head with overhead camshaft operating 4 valves per cylinder and the injectors. This contributes to smooth running, high reliability and long-term durability. The D13 engine is manufactured by the Volvo Group, the world’s largest manufacturer of heavy-duty diesel engines for commercial use. The generator is from market-leading Newage Stamford and the complete gensets are assembled and tested at Volvo Penta.

The D13 MG is easy to service and has a 500-hour service interval.

Fully classed, fully emission-approved

D13 MG genset comes complete with Volvo Penta’s MCC control system, a flexible and expandable system for classified installations. MCC is easy to interface with leading suppliers of ship control systems. The engine meets the latest EU IWW, CCNR, IMO and EPA emission legislation requirements.

The engine is fully classifiable to meet the demands of all major classification societies.
