Volvo adds New D13-900 Engine to its Power Line


Volvo Penta has built upon its high horsepower line of marine engines for 2010 with the D13-900. A successor to the popular D12, the D13 is designed to power express cruisers, motor yachts and sport fish yachts from 50 to 70 feet with additional features to deliver improved power, fuel-efficiency and emissions.

The D13, an in-line six-cylinder diesel, has an extensive series of refinements including what the company calls its new dual-stage turbo technology. The first stage of the system uses a twin-entry turbo that utilizes pulse charging, which allows power in each exhaust pulse to provide pulse pressure that results in very high torque from low rpm.  At higher rpm, a second turbo kicks in so the engine retains power even at higher rpm.

The D13 has a maximum torque of 3,300 Nm at only 1,300 rpm/min and is designed to retain a very high torque throughout its speed range.

Other technical features include Quick Shift reverse gears, allowing very fast but soft shifting with a minimum delay. The gear also has a standard low-speed function, providing users the ability to drop idle speed from six to three knots, quickly and easily.

The D13 is equipped with EVC, the company's electronic platform, which includes electronic shift and throttle from the controls to the engine and drive. The system also makes it simple to install additional accessories and functions such as a trip computer, engine data in the chart plotter via NMEA or colour displays. It even offers the ability to have instrumentation or complete helm stations for up to four locations onboard.

According to Volvo Penta, the benefits of the D13 extend to an exceptional power-to-weight ratio, optimum low-end torque, and extremely low emissions and smoke levels.

The D13 meets the EU RCD and US EPA Tier 2 standards, and is prepared for the EPA Tier 3 emission standards to be introduced in 2012.
