More power for Volvo Penta IPS
In 2008 the increasingly successful Volvo Penta IPS range is strengthened by two new, more powerful models. The smallest leisure boat engines are also new and for the first time, gasoline boat engines with catalytic converters are available. Diesel electric propulsion is becoming more popular in the marine commercial side, offering environmental benefits. A new top-of-the-line industrial engine is introduced, complying with the most stringent emission regulations.

The Volvo Penta IPS system is expanding with two more power classes: IPS900 and IPS800.

The new packages will be installable on boats up to 100 feet and thereby offer never-seen-before features for the environment, maneuvering, comfort and performance on this type of boat.

Larger engines with greater power and more than twice as much torque place enormous demands on drive units. Volvo Penta has therefore developed a larger and considerably more powerful IPS drive unit and a new propeller series for the IPS800 and IPS900.

The larger drive unit provides all the advantages and characteristics that made the original IPS system so successful.

The engine for the new power classes is Volvo Penta’s 11-liter engine, D11, with 700 hp or 600 hp.

The IPS system is generally available as a dual installation, but in order to offer the system on larger boats, IPS is also available as a triple installation and quad installation. A quad installation of Volvo Penta IPS900 generates the equivalent of 3,600 horsepower.

Introducing the first gasoline engines for leisure boats fitted with a catalytic converter
The engines have very low emissions and satisfy California CARB 4 star requirements, the toughest gasoline emission regulation in the world. Volvo Penta’s new gasoline engines, equipped with catalytic converters, offer very low emission levels. The catalytic converter components are fully integrated into the aluminum exhaust system.

The catalyzed sterndrive engine program consists of one 150 hp 4-cylinder engine, two small-block V8 engines developing 270 hp and 300 hp respectively, and one 400 hp big-block V8 engine.

New versions of the D1 and D2, the smallest diesel engines in the program
The biggest news is on the environmental side. Particle emissions have been reduced by as much as 50%. 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.

Major environmental benefits with diesel-electric power at sea
With Volvo Penta’s 16-liter engine, environmentally harmful emissions are just a fraction compared with conventional ship diesels.

The conventional ship diesel is connected mechanically to the ship’s propeller via a reversing gear and driveshaft. The engine’s rpm is the only way to affect the propellers, and thus the ship’s speed. With diesel-electric power, the ship has a number (often four to six) of smaller diesel engines that each drive a generator. The electricity produced powers one or two drive units located under the ship’s hull. In this way, speed can be controlled through the electric engines in the drive units and by varying the number of diesel engines in operation.

In applications with major variations in the vessel’s cargo and speed, diesel-electric operations often delivers better fuel economy while significantly lowering emissions. These are two areas that are becoming increasingly important for the world’s shipping companies. Instead of bunker oil containing sulfur, the engines in a modern diesel-electric system operate with the same type of diesel fuel used in, for example, trucks. Environmentally harmful sulfur emissions are reduced to a fraction.

TAD1650VE: Volvo Penta’s most powerful engine for off-road and stationary applications
The TAD1650VE produces 400 kW at 1800 rpm with a virtually flat torque curve of 2,500 Nm over the speed band 950-1500 rpm and peaking at 2,550 Nm at 1400 rpm.  The engine combines impressive power and torque with exhaust emissions that comply with the world’s most stringent regulations, EPA/CARB Tier 3 and EU Stage 3.

Fuel quality can sometimes prove to have harmful effects on emissions-certified engines. The TAD1650VE is manufactured with a worldwide specification and is designed to operate using all commercially available fuel qualities.
