New Volvo Penta IPS – more power, better maneuverability with less emissions



by Volvo Penta

Volvo Penta's world-leading IPS drive system is now updated with a new generation of the proven D11 engine. Two new drive packages comes with power levels up to the equivalent of 950 hp, higher torque, better drivability and significantly lower noise levels and emissions. The result is a highly fuel-efficient power package tailored for 40- to 60-feet boats.

With steerable drive units and double forward-facing propellers, the IPS system provides about 30 percent lower fuel consumption and 20 percent higher top speed compared with traditional shaft installations.

Today's IPS program with the D11 engine is increased from the existing 600 and 700 hp, and is now offered in 625 and 725 hp with an upgraded basic design. The result is two new and reliable drive packages – IPS800 and IPS950 – both with Volvo Penta's classic quality: a unique high torque.

“The mechanical compressor increases the charging pressure directly from low rpms and now creates an even more powerful low-speed torque. Together with the double forward-facing and counter-rotating propellers you get an extremely good grip in the water. The drive packages are more responsive to commands and together with the joystick control the result is a significantly improved maneuverability in port environments,” says Thomas Lantz, Chief Product Manager at Volvo Penta.

With the latest diesel technology that the Volvo Group has to offer, Volvo Penta now sharpens the D11 generation with additional technical upgrades.

“This means for example that we also improve our twin-entry turbo where each exhaust pulse now is maximized to provide charging pressure at high revs. This results in increased top speed and better acceleration,” says Thomas Lantz.

The IPS800 and IPS950 are two perfectly matched drive packages and will become the natural choice for 40- to 60-feet flybridge yachts and sports cruisers.

“Based on the D11, the new IPS models deliver tremendous power and strength throughout the rev range, and you will be amazed at how maneuverable these boats are. The drivability is great at both high and low speeds and the driving joy is total,” says Thomas Lantz.

Improved comfort
With the new IPS models, the onboard comfort has also improved significantly.

“Thanks to a new and more efficient silencer, a new turbocharger and an air filter with improved insulation, the sound levels have been reduced by 2 dB, which is a clearly noticeable difference. At the same time, the robust engine design contributes to minimizing the on-board vibrations,” says Thomas Lantz.

Lower emissions
The emission levels for Volvo Penta IPS is already about 30 percent lower compared with traditional shaft installations, and with the IPS800 and IPS950 further improvements are achieved.

“With advanced technology we manage to create an optimized air and fuel pressure ratio, which gives very efficient combustion. And with increased intercooling, we acquire more engine power altogether,” says Thomas Lantz.

Thanks to the efficient combustion, the new IPS models comply with the world’s most stringent environmental legislation, U.S. EPA Tier 3, which comes into force in 2014. The particulate emissions will then be 40 percent lower compared with today’s levels.

Upgraded basic construction
The IPS800 and IPS950 will by far be able to live up to our customers’ expectations regarding the qualities that characterize Volvo Penta in terms of safety, reliability and service life.

“We have, among other things, developed a strong and robust engine block and a new cylinder head with improved cooling, which gives the engine a more even service temperature. The result is a very reliable engine with a long life,” says Thomas Lantz.

Integrated with the latest EVC
The engines use the latest generation of Volvo Penta’s electronic platform, the EVC (Electronic Vessel Control). The latest generation of EVC enables an additional number of features for increased security and control, and improved functionality.

Customized installations
Volvo Penta IPS is a unique and flexible system and is available from double, triple and quadruple installations. The wide IPS program with several different drive packages enables the boat owner and boat builder to find the optimal drive system for different types of boats from 35 to 100 feet.

Simple installation and service
The new D11 series that the new IPS models are based on has the same installation dimensions as before which is beneficial to the boat builder. All fuel and oil filters, oil dipstick and oil filler are gathered in back of the engine where they are easily accessible for servicing.

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 percent.

Facts
Tier 3 - background: Tier 3 originates from the U.S. Clean Air Act written by the Environmental Protection Agency from 1990. In this, a multi-step plan with a number of "tiers" – deadlines for engine manufacturers – was established. Shortly thereafter, the EU adopted a similar multi-step plan. To be approved according to the Tier 3 requirements, the levels of particulate emissions must be reduced by 40% and nitrogen oxide emissions must be reduced by 20% compared with previously (Tier 2), which means an emission ceiling of 5.8 g / kWh and NOx. The emissions requirements associated with the different tiers are a guarantee that the work towards cleaner air and environment steadily continues.
