New D13-800 More power at less fuel and emissions

Last year, Volvo Penta introduced its most powerful engine ever – the 900 hp D13 – an immediate success that is now being followed by an 800 hp version. The engine is in fact a direct successor to the legendary D12-800, only more powerful, more fuel-efficient and cleaner.

“The D13-800 does everything the D12-800 does, and a little better in every respect,” says Lennart Sellman at Volvo Penta product planning. 

Unique marine torque
One characteristic of Volvo Penta’s inboard diesels is their high torque from low rpm, a prerequisite for rapid and safe acceleration.

The new D13-800 is equipped with Volvo Penta’s highly efficient twin-entry turbo with pulse charging – the power in each exhaust pulse is used to provide pulse pressure – which results in a very high torque from low rpm.  The D13-800 reaches its maximum torque of 2900 Nm at only 1300 rpm/min, a uniquely high torque for this class of engine. This gives powerful acceleration up on the plane, which is important for comfort as well as safety.

Another important feature is that the D13-800 retains a very high torque throughout its speed range. This makes it possible to maintain a good cruising speed even with a heavily loaded boat or in a rough sea.

Low fuel consumption, minimum emissions
Highly efficient combustion is a prerequisite for low fuel consumption and low emissions. EMS 2, the engine control system developed by Volvo Penta, regulates fuel injection. The system controls the unit injectors, one per cylinder, which operate at a pressure of as much as 2000 bar and atomize the fuel for optimum combustion. The result of this efficient combustion is lower fuel consumption for the D13 than the D12 at the same power output.

Exhaust emissions are also lower than ever before. Total emissions satisfy by a wide margin the EU RCD and US EPA Tier 2 regulations.

Quick shift and low speed
The D13 is available with quick-shift reverse gears.

“This is a very useful function that provides very fast but soft shifting with a minimum delay. The reverse gear also comes with a low-speed function as standard, which means that the speed when idling drops from about six knots to three knots. You can drive safely in a harbor without having to go to neutral to slow down,” says Lennart Sellman.

Integrated electronics
The new D13-800 is equipped with EVC-D, the fourth and latest version of Volvo Penta’s electronic platform, which includes electronic shift and throttle all the way from the controls to the engine. EVC-D offers a complete series of new controls with a high level of styling, ergonomics and overall driver experience. EVC functions are easily managed through push-buttons on the control head.

“Single-lever function” gives the possibility to control the speed of all engines in a multiple installation with one lever.

“Cruise control” allows the driver to fine-tune the engine speed in increments using the integrated push button as an alternative to the lever.

“Low speed mode” reduces boat speed at idling by 50%.
