Scania marine engines get XPI fuel injection technology

Scania Press Release / August 31, 2015

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

Scania’s new, more powerful marine engine range now features the company’s 2500 bar 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 up-time to be maintained at the high level that Scania expects.”

Smaller footprint

The V-8 version of Scania’s marine engine is based on the company’s tried-and-tested 16.4-litre V-8 for trucks. The engine is the most powerful in the marine range and is capable of producing up to 1,150 horsepower for use in working boats. While this represents an increase in power on the previous generation, the physical size of the complete installation has actually decreased making it easy to upgrade an existing V-8 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.”
