Continuing the success of Scania’s new global engine platform, enter the latest 16-litre marine V8 delivering up to a whopping 1,000 hp and 3340 Nm for patrol craft applications. While passing this new threshold, the new V8 builds on a long tradition of amazingly compact power packs that share both technology and architecture with Scania's truck and bus engines. The high power-to-weight ratio of Scania's engines makes for easy installation and exceptional performance.

The official world premiere will be 22-24 May at the Seawork exhibition in Southampton, UK where Scania's new 16-litre and the 13-litre marine engine will be showcased.

Docked by the pontoons there will be two Scania-powered vessels, a pilot vessel and a wind farm support vessel, both with Scania 16-litre marine engines of previous engine platform.

Intended for both propulsion and auxiliary use, the engines are all based on Scania's new state-of-the-art modular engine platform, which is used for truck, bus, industrial and marine applications worldwide.

Engine-by-engine, the new range has been designed for higher strength and durability. Swept volumes have increased somewhat and performance has been boosted. Many components are shared across the range, a factor that facilitated parts supply, since it significantly reduces the number of unique parts for used each engine. The modular architecture and common work methods simplify training in Scania's service network, while maximising uptime for users.

Scania secures control of all strategic steps in development and performance control. Basic engine development and manufacturing as well as the development of engine management, fuel injection and emission control systems are all carried out in-house. This strategy is motivated by performance and fuel economy demands and targets, as well as by the need to secure consistent environmental performance, robustness and convenience of operation.

16-litre V8s from 550 to 1,000 hp

Important features for the marine engine segment are reliability, high uptime, generous torque at low revs, good fuel economy and prompt engine response.

The output of the new 16-litre marine engines spans from 550 hp for continuous use to 1000 hp for patrol craft use. Ratings have been uprated for planing as well as displacement vessels and Scania's engines are now highly competitive with engines well above 16-liters.

The torque ratings of up to 3340 Nm are particularly high for this output class. This ensures ample performance even at low revs, while facilitating running at favourable revs in all conditions, including high sea and high load.

In all types of automotive, industrial and marine applications, Scania's new engine platform is renowned for its high efficiency, providing very good fuel economy irrespective of operation.

Compact V8 power pack

Vital for marine installations is that the engine is compact, has easy-to-fit auxiliaries and is designed for easy servicing. Scania's V8 engines traditionally meet all of these requirements thanks to the compact vee-design, which reduces the overall length. Ancillaries can be efficiently accommodated inside the 'footprint' of the engine.

Most repairs and servicing can be carried out by a single service technician, since each cylinder has its own head, which together with wet cylinder liners makes for easy overhauls in confined spaces. The camshaft is located high in the block and the timing gears are rear-mounted.

The Scania Saver ring, placed at the top of each cylinder liner, reduces carbon deposits on the edge of the piston crown and reduces cylinder liner wear.

Extended maintenance intervals

Scania's familiar centrifugal oil cleaner effectively removes small particles from the lubrication oil, while reducing the size of the replaceable filter cartridge. In spite of higher performance and tighter emission levels, Scania has been able to raise maintenance and oil-change intervals to 500 hours.

High-performance inline sixes

The 13-litre inline six-cylinder engines introduced in 2011 produce 400 hp for continuous use and up to 750 hp for patrol craft use. Installation principles and maintenance requirements are the same as for the new 16-litre V8.

Instrumentation optional

Scania has also developed an instrumentation for its marine engines that is easy to install. Via a user-friendly and flexible web interface, the marine operator can adapt the information on the panels and choose any required data to be displayed. The panels have prepared layouts for water temperature, engine speed, oil pressure and fuel consumption. The operator can also connect and configure a gauge indicator for transmission monitoring and for fuel or fresh-water levels. The instrumentation is type approved by the DNV classification society.

Key characteristics of Scania's marine engine range

  • Compliance with emission standards IMO II, EU Stage IIIA and US Tier 2
  • Scania PDE unit injector fuel injection
  • Revised bore and stroke for increased swept volume
  • Increased combustion pressure
  • Traditional easy-to-service Scania architecture with individual cylinder heads
  • Scania engine management
  • Waste-gate turbocharger(s)
  • Saver ring at the top of the cylinder liners to prevent coke build-up on the piston
