Volvo Penta launches updated D16 engine family
Volvo Penta has launched an updated version of its 16-litre D16 engine family. The engine is being made available as a heavy duty propulsion engine for heavy-duty and continuous-duty applications, and as a complete marine genset and auxiliary.
Volvo Penta has launched an updated version of its 16-litre displacement engine family, which is being made available as a heavy duty propulsion engine for heavy-duty and continuous-duty applications. The engine is also available as a complete marine genset and for auxiliary installations.
The engine has now been upgraded to produce even more power as part of a wider move within Volvo Penta to increase the power of its engine platforms.
One of the most notable updates to the D16 engine platform was the use of Twin Turbochargers. Volvo Penta uses Twin Turbochargers with a wastegate. Separate exhaust manifolds enable pulse charging resulting in high torque at low rpm.
The upgraded engine now includes an electronically controlled Unit Injector. The Unit Injector, along with the advanced engine calibration, enables high efficiency and low noise levels. Volvo Penta has used robust steel pistons, well proven in other applications, and optimized them together with this injector, to further enhance efficient combustion and durability.
The base engine is fresh water cooled including the exhaust manifold, turbocharger, oil cooler and charge air cooler. The platform also features a new higher capacity heat exchanger to ensure the cooling performance needed to manage the higher power output.
The upgraded D16 engine now comes in three package options – D16 MH Inboard, D16 MG Marine Genset, and the D16 MH/MG IMO III.
The new D16 MH for variable speed engine is available for both propulsion and auxiliary use for marine commercial applications. The 6 cylinder in-line design features increased power (441 to 625 kW and 600 to 850 mhp) for continuous duty and heavy-duty applications. Volvo Penta claims that the D16 MH offers high torque with output ratings from 600bhp to 850bhp. The reserve of torque facilitates manoeuvring, and rapid acceleration.
Operators can select either EVC or MCC monitoring and control systems or the engine can be supplied with an open CAN solution.
The complete engine package also available in several different emission limit options: IMO II, IMO III, US EPA Tier 3, and China 2.
D16 Marine Genset
The D16 MG for Auxiliary and Marine and Auxiliary Genset is also compliant with the global emissions standards – IMO II, IMO III, US EPA Tier 3, and China 2.
With the same specifications, this solution is available in a range of electrical outputs ranging from 532kVA at 1,500rpm, 50Hz to 585kVA at 1,800rpm, 60Hz. The engines have another 10 percent power to meet the class demands of 500 kWe and 550 kWe nodes.
D16 MH/MG IMO III
Volve Penta also announced that it was extending its selective catalytic reduction (SCR) technology to the D16 platform. The IMO Tier III regulations come into force in 2021 in the North and Baltic seas and demand a 75% reduction of NOx emissions. Keeping well ahead of the game, Volvo Penta launched its own IMO III compliant solution in 2018. This has accumulated 65,000 hours in various tests and operations at sea on the smaller D13 platform.
The SCR system can be delivered as a ‘plug and play’ package that includes UREA tank, dosage valve and UREA quality and level sensor.
