Swedish engine manufacturer Scania pulled the sheet off a new six-cylinder, 13-liter diesel engine at the International WorkBoat Show, which took place Dec. 3-5 in New Orleans. The new ps2024 will replace the e2011 that is being phased out. The ps2024 is expected to be available in June 2026.
“This engine is sustainability focused,” said Ernie Ortega, marine sales manager for Scania’s U.S. headquarters in San Antonio, Texas.
The engine can deliver up to 30% more power and increases fuel economy by 7%, while reducing exhaust emissions by the same number. Ortega said that many customers who came to the booth said they were “perfectly happy” with their e2011s but added that they would be even happier with the increased fuel efficiency. The engine can run on 100% hydrotreated vegetable oil and up to 20% biodiesel without sacrificing performance.
The ps2024 is designed for inboard, waterjet, and other applications. Scania thought ahead with the design, and the engine will be available with a hybrid option in 2027.
Thanks to its monoblock design, the ps2024 has a compact profile that should make it popular for repowers. The block and rotating systems are new, and the lubrication and cooling systems were reconfigured to improve thermal efficiency. Fuel is delivered by a common-rail system.
The engine was also laid out to make it easy to find components for routine maintenance. The starboard side has the turbocharger and aftercooler installed in a position so they don’t extend higher than the top of the overall unit, which means a low profile for fitting beneath a cockpit deck. Forward are the alternators that make more electrical power than ever before. The port side has dual oil filters with a selection lever that makes it easier to replace one or both. The fuel filters are on the back of the engine, where the fuel intake and outlet connections are easy to reach. No more technicians standing on his or her head. Up high on the port side are the electrical connection ports that will make rigging navigation and monitoring equipment much easier than on previous engines.
