Marine Inboard Engines

Volvo Penta D11-625 is an in-line 6-cylinder, 10.8-liter diesel engine using common-rail fuel injection, overhead camshaft, and a twin-entry turbo using a water-cooled exhaust manifold. This contributes to excellent operating economy and world-class diesel performance, combined with low emissions.

Product Highlights

  • The engine is designed and built to be immensely strong, with a rigid cast-iron cylinder block and cylinder head. This gives high reliability and long-term durability.
  • The unique marine torque of the Volvo Penta diesel engines stands out among the competition by offering increased load-carrying capability, rapid acceleration, and the ability to maintain a high cruising speed, irrespective of load or sea state.
  • The high-tech fuel injection system helps make the engine highly fuel efficient. The control unit monitors several parameters which reduces the overall fuel consumption.
  • Together, the engine’s large swept volume and the electronic management system result in a very smooth-running engine with world-class diesel performance, low fuel consumption and low emission levels.
