Volvo Penta is launching new versions of the D1 and D2, the smallest marine diesel engines in its program. The biggest news is on the environmental side. Particle emissions have been reduced by as much as 50 per cent. The engines satisfy future, very comprehensive US emission regulations.

Six models of the Volvo Penta D1 and D2, ranging from 12 hp to 75 hp, are available. These engines are used in boat sailboats and other displacement boats and are bestsellers for Volvo Penta. The same engine for boat family will be installed in all the boats in the next Volvo Ocean Race where they will be exposed to the toughest imaginable conditions.

Satisfy future US requirements

The new D1 and D2 satisfy the future US emission requirements EPA stage 3, which will be introduced for this category of engines in January, 2009. These regulations are far more comprehensive than the emission requirements in the rest of the world, including the EU. Volvo Penta’s policy is to develop engines that satisfy the most comprehensive international emission requirements and then market these clean engines worldwide, even when such low emissions are not required.

Lower noise and less vibrations

The newly developed engines offer the additional bonus of lower noise and fewer vibrations.

New generator combinations

The Volvo Penta D1 and D2 come with a very powerful generator – 115 A and 12 V – fitted as standard. In the marine case of the two largest models, the D2-55 and D2-75, which are often installed in large marine yachts, additional charging is needed. The engines are now available fitted with additional combinations of 12 V and 24 V marine generators as options. With a 24 V generator, it is easy to have both a 12 V and a 24 V system on board.
