The Volvo Penta stands at this year’s winter exhibitions will be filled with innovative new products. In the diesel engine segment, Volvo Penta is strengthening its position in all kinds of ways with a range of new engines and drivelines. A new engine will also be launched for large sailing boats, while the new EVC electronic platform signals the start of a completely new method of controlling all of the onboard electronic systems in a boat.
D4 and D6
The completely newly developed D4 and D6 represent a new generation of diesel engines for Volvo Penta. Their advanced electronic engine control, common-rail direct fuel injection, four-valve technology and turbochargers provide the kind of performance and environmental properties that until now have been considered impossible. Powerful torque is combined with high output and low exhaust and noise emissions. The D4 and D6 will meet the overall environmental requirements planned for Europe and the US in 2006.
The D4 is the smaller of the two with four cylinders and 3.7-liter volume. The engine has a very compact external dimension, with an output of 210 hp. In terms of performance, the D4 is similar to a V6 petrol-powered engine, while the external dimension is comparable to a V8.
The D6 has the highest output of the Volvo Penta diesel aquamatics. Six in-line cylinders, 5.5-liter cylinder volume and a full 310 hp output create a performance that is hard to beat.
Both the D4 and D6 are available with Volvo Penta duoprop drive and as inboard engines with hydraulic transmissions. The new Duoprop DP drive is exclusively developed for the D4 and D6, which ensures excellent performance and high reliability. Fully hydraulic servo steering is standard and a completely new range of propellers has been developed. The propellers are constructed from a nickel, aluminum, bronze alloy and are available in nine different sizes for speeds of up to 45 knots. For faster craft, Volvo Penta has developed a DPR drive.
D3
The new Volvo Penta D3 is a technically highly advanced five-cylinder diesel engine constructed completely in aluminum. With its low weight of just 215 kg and high output of 130 or 160 hp, the D3 is the perfect choice for sports boats of up to 8 meters in length. Acceleration from a standing start is extremely impressive, thanks to the torque, which reaches a full 340 Nm at a low 1750 rpm for the 160-hp version.
The basic construction is the same as Volvo Car Corporation’s recently launched diesel engine, which was given a successful reception by the auto trade press and customers.
The new D3 lacks nothing in the way of high technology. The fuel system is electronically controlled, common-rail direct fuel injection and operates at a full 1600-bar pressure. Duel-inlet manifolds per cylinder and four-valve technology provide very efficient fuel flow. Moreover, the inlet manifolds are vertically positioned, which enables a fast mix of fuel and air. The VGT model turbocharger means the geometry adjusts to meet demand. All of these features create the conditions for the most effective use of fuel, which gives low fuel consumption and emissions that will meet the overall environmental requirements planned for Europe and the US in 2006.
The D3 is available with the Aquamatic SX single propeller drive, or as an inboard engine with a hydraulically operated gearbox.
D2-75
Two years ago, Volvo Penta launched the D2-55, which became a great success for mainly sailing boats. Now, the company is launching the new D2-75, which is basically the same engine supplemented with a wastegate turbocharger and charge-air cooler. The new 75 hp engine operates at a low rpm. The engine has very powerful torque and low emissions – properties that make it ideal for sailing boats and for small planing motorboats. The engine also comes with a new version of Volvo Penta’s well-known Saildrive.
The torque in the D2-75 is powerful, especially in the low rpm range, with a maximal 210 Nm at 2,000 rpm. This gives the driver ample power for simple and safe maneuvering Exhaust emissions are minimal and the D2-75 will meet the overall environmental requirements planned for Europe and the US in 2006.
A full 115 amp alternator combined with Volvo Penta’s integrated charge sensor provides charging that will satisfy most demands. A 220-volt alternator delivering 2.2 or 3.5 kW of alternating current comes as an accessory.
With the new 150 S S-drive, Volvo Penta increases the output range for its S-drives to 75 hp. The 150 S also has a number of attractive new features: For example, it is now possible to change the oil in the drive from within the boat and the anode is split so that it can be replaced without the having to dismantle the propeller. The S-drive can be turned through 180 degrees, so that the engine may be positioned at either the front or the back of the boat.
In addition to the S-drive, the D2-75 is also available with traditional gearbox for straight or angled shaft and with different gearing.
D12 with EVC
The 12-liter D12 engine, which was introduced in 2000, is today the undisputed leader within the flybridge boat segment and sports cruisers measuring up to approximately 60 feet. The D12, which has always featured advanced electronic engine control, has now been equipped with Volvo Penta’s new Electronic Vessel Control (EVC) platform. EVC provides many advantages, particularly for large leisure craft, for which the potential to integrate new functions in the same network results in simplified installation and radically reduced cable-laying requirements.
Electronic Vessel Control (EVC)
Electronic Vessel Control (EVC) is the name given to Volvo Penta’s new electronic platform. EVC is a common system through which the engine, controls, instruments, as well as other onboard functions, can communicate and exchange information. The system is highly flexible and expandable, and can also be upgraded with new software.
EVC is based on modern CAN-bus technology, which is extensively used within the automotive industry. Using EVC, Volvo Penta has developed a system specifically to meet the requirements of modern boats. All connections are watertight, cables are heavy-duty and the processes themselves are robust and reliable. EVC meets the classification requirements for professional users.
EVC is now being launched in combination with Volvo Penta’s electronically controlled diesel and petrol-powered engines. The system comes in two versions: one with an electronic engine control unit adapted for larger boats, and one with a traditional mechanical control unit for smaller boats. Volvo Penta is also launching a new instrument and display series, specially designed for EVC.
The system offers many advantages, including simplified and more reliable installation, and additional instruments can easily be installed. Another advantage is that the information delivered to the instruments and displays is always very reliable. Messages and warnings are easily seen by the driver. The trim function for Aquamatic powered boats is improved through opportunities to limit the tilt angle and to attain automatic synchronization in conjunction with twin installations.
