The new Volvo Penta D13 MH for medium-and heavy-duty marine commercial applications is a powerful and fuel-efficient Tier 3 engine.
D13 MH marine diesel engine
The company says that this 13l diesel engine combines the best of two worlds: the exceptional durability, low fuel consumption and minimal emissions that come from its automotive background and the high torque and power brought by the thorough marinization. D13 MH is available in five models with outputs from 400-600hp.
Maximum torque is reached at around 800-900rpm which facilitates maneuvering, but is equally important when towing at low speed, using the power take-off, performing a crash stop and more.
The D13 MH has very low levels of NOx emissions and no visible smoke, regardless of load. The low emissions are combined with high power and low fuel consumption, thanks to the advanced and efficient charge air system. The D13 MH 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 utilise this turbo, it is combined with Miller inlet valve timing. Here, 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 MH features a plate heat exchanger technology.
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 atomise the fuel for optimum combustion. The result of this is around 4% lower max power fuel consumption for the D13 MH than the previous model. For an operator running round the clock, this is an important saving. Noise levels are also low and at operational speed the reduction is significant compared to the existing model.
The D13 MH has the same robust basic architecture as the engine platform for 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.
D13 MH is available with two type-approved onboard electronic control alternatives: EVC or MCC. EVC is Volvo Penta’s own electronic platform with integrated controls and features such as low speed and cruise control. MCC is the option for the operator who needs a system fully classified for all Solas and society demands, including ocean-going.
The D13 MH features a self-diagnostic function, which indicates at the helm if a failure should occur. The engine has a compact and clean design, with all fluid filters plus seawater pump positioned at the port rear end, which makes it easy to service and maintain. The 500-hour service interval makes for good uptime.
D13 MG marine genset engine
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.
As with all Volvo Penta marine gensets, the D13 MG is delivered complete with electric generator and onboard electronics, tested and classified.
Again, EMS 2 regulates fuel injection and monitors engine conditions.
The D13 is available with keel cooling, heat exchanger or radiator cooling from the introduction. This means it is ready to use for a number of applications, auxiliary, harbor operations, emergency and diesel electric propulsion.
The noise level of the D13 MG has been further reduced thanks to variable injector pressure and a new, efficient cooling system.
The D13 MG has very low levels of NOx emissions and no visible smoke, regardless of load. This is combined with high load acceptance, 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. Again, it is combined with Miller inlet valve timing and features a plate heat exchanger.
The D13 MG has the same robust basic architecture as engine platform used for the D13 MH above.
D13 MG genset comes complete with Volvo Penta’s MCC control system, a flexible and expandable system for classified installations.
