Marine Engines

Unrivalled fuel efficiency


The latest additions to Scania’s engine range for marine applications incorporates proven XPI fuel injection technology, allowing for unrivalled fuel efficiency. The new 13-litre and the 16-litre V8 are also the most powerful engines in the range, boasting effects from 650 to 1,150 hp.

These powerful engines now feature the company’s common-rail XPI fuel injection system, long used in Scania’s engines for trucks and industrial applications.

Boosting power

Svante Lejon is a senior technical adviser within Scania’s Research and Development division and his responsibilities include developing technical performance concepts for industrial and marine engines.

“The XPI system introduces more fuel into the cylinders in a shorter time, providing more power,” he says. “However, this also places higher demands on both the filtration system and the cleanliness of the fuel, as the system is more sensitive to particles.”

Lejon says the challenges involved have meant that Scania has not previously used common-rail technology in its marine solutions. “The fuel quality required for marine applications is different to that for trucks and industrial applications,” he says. “However, filter technology has now reached a level that allows for performance and uptime to be maintained at the high level that Scania expects.”

Small footprint

These marine engines are based on the company´s tried and tested equivalents for truck applications. They are the most powerful engines in the marine range, capable of producing between 650 and 1,150 hp for use in work boats. While this represents an increase in power on the previous generation, the physical size of the complete installation has remained the same making it easy to upgrade an existing installation to the new engine platform.

Scania’s modular system in combination with the company’s Engine Management System (EMS) allows for the same platform to be used in different applications. An engine solution can thus be tailored for completely different operating profiles without compromise.

“It’s thanks in part to Scania’s Engine Management System that we’re able to optimise our engine platform for such a wide range of areas,” says Lejon. “Otherwise, we would be forced to make an engine that wasn’t as good for each area.”
