Volvo Penta launches new engines


Offered in three power classes – 625, 670 and 725 hp — the new D11 engines provide more powerful torque, improved drivability and reduced noise levels compared to other engines in these horsepower classes, the company said in a news release.

“In addition to a wider range of power classes, the in-line, six-cylinder diesel engines are enhanced with a large number of technical upgrades,” said Marcia Kull, vice president of marine sales in North America for Volvo Penta of the Americas in Virginia.

The D11 is suited for fly bridge yachts, express and sports cruisers, said Thomas Lantz, chief product manager.

“The weight of these boats typically places high demands on the engine performance,” he said. “We have enhanced our twin-entry turbo where each exhaust pulse maximizes charging pressure. The D11’s high torque at low RPMs produces rapid acceleration to plane, enhancing safety, fuel efficiency and comfort.”

Onboard comfort is also enhanced by the reductions in noise and vibrations. The engines offer more power with less environmental impact.

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

The new D11 series complies with the world’s most stringent environmental legislation, U.S. EPA Tier 3, which comes into force in 2014. The particulate emissions are 40 percent lower compared with today’s Tier 2 levels.

The engine will be available for both traditional inboard installations and Volvo Penta IPS with the newly launched IPS800 and 950.

The new IPS drive packages provide higher torque, better drivability and lower noise levels. With steerable drive units and double forward-facing propellers, the Volvo Penta IPS system provides about 30 percent lower fuel consumption and 20 percent higher top speed compared with traditional shaft installations.

All engines in the series have the same installation dimensions as before. All fuel and oil filters, oil dipstick and oil filler are gathered in the back of the engine for servicing, meaning the same engine specification can be used for port and starboard installations.
