Marine Engines

Unrivalled fuel efficiency

Scania’s fuel-injection technology in the marine

The latest addition to Scania’s engine range for marine applications incorporates proven XPI fuel-injection technology, allowing for unrivalled fuel efficiency. The new V8 engine is also the most powerful engine in the range, boasting up to 1,150 hp.

Scania’s more powerful marine engine range now features 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.”

Smaller footprint

The V8 version of Scania’s marine engine is based on the company’s tried-and-tested 16.4-litre V8 for trucks. The engine is the most powerful in the marine range and is capable of producing up to 1,150 hp for use in working 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 V8 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.”
