Following the successful launch of the US EPA Tier 3 11-liter marine diesel engine in 2013, the D11 model has been updated and undergone the tests needed order to achieve approval by several classification societies.*
Proven success
“We’ve seen great success already with this engine in pilot boats, passenger transportation and fishing vessels, and it’s a great step forward that our 11-liter engine has been type approved. With type approval, it will be available for a much wider range of high-speed applications all over the world,” says Thomas Lantz product planning manager for Volvo Penta’s Marine Commercial sector.
The engine has high torque at low rpm and allows the boat to accelerate quickly to planing level. Its excellent performance and handling have made it an ideal choice for a wide variety of applications, and is already used in applications that do not require type approval.
“The 510hp model in particular complies with demands of classification societies in relation to unmanned machine rooms, so we see this as continuing in popularity. The D11 really strengthens our total commercial offer by adding the new ratings both in our inboard and IPS high speed engine range,” adds Lantz.
Technical highlights
The D11 is an in-line six-cylinder engine, with the latest technology from the Volvo Group and further developed and optimized for commercial use by Volvo Penta’s development team.
It fills the gap between D6 and D13 with two power classes: 510 and 625hp both in the inboard and the IPS range.
The D11 series will by far be able to live up to customers’ expectations regarding the qualities that characterize Volvo Penta in terms of reliability and service life. With a strong and robust engine block and cylinder head with efficient cooling, which gives the engine a more even operating temperature, the result is a very reliable engine with a long life.
It is equipped with a twin-entry turbo where each exhaust pulse is used maximally to provide charging pressure. This gives an extremely powerful torque at low revs. The engine responds instantly to control commands and provides good drivability and strong acceleration, making the boat reach plane quickly, which is important both for fuel consumption and comfort.
Thanks to an efficient turbo and air filter with noise reduction, the perceived noise levels are significantly reduced. At the same time, the robust design helps minimize the on-board vibrations.
Volvo Penta IPS is a unique and flexible system available in double, triple and quadruple installations. By widening the commercial IPS program more operators can find their optimal drive system for different types of boats, taking advantage of all IPS benefits. The IPS installation is delivered in a complete package from Volvo Penta. And compared with a setup with shafts, the installation time has been reduced by more than 50 per cent.
The D11 engine conforms to the US Environment Protection Agency’s Tier 3 emissions standards.
Based on the architecture of the 11-liter model released 2013, the new type-approved engine has the same dimensions and features but with some modifications.
- Simple installation and service. All engines in the series have the same installation dimensions. All fuel and oil filters, oil dipstick and oil filler are gathered in the back of the engine where they are easily accessible for servicing with a choice of oil dip stick location – on either the left or right side.
- Latest version of the electronic system (EVC) gives features such as alarm handling display and log, and manual engine synchronization (to support complex maneuvers in dual engine installation).
- Shut-down system as an option with different levels depending on application and class rules.
- New front power take off system – with a front belt pulley and a stub shaft.
The EVC’s top-mounted controls and display have all been updated to exceed the DNV-GL requirements, to fulfil the international Ingress Protection rating of IPx7 – in accordance with IEC standard 60529 – which states that a component must be able to withstand an incursion of water to a depth of one meter for 30 minutes.
*Classification societies include: Det Norske Veritas - Germanisher Lloyd (DNV-GL), Registro Italiano Navale (RINA), Lloyds Register (LR), China Classification Society (CSS), Russia Maritime Register of Shipping (RS) and the Indian Register of Shipping (IRS).
