The design evolution within Yanmar's technology creates engines which not only perform, but also last and last. That's our mission. This has led to a worldwide reputation for unsurpassed reliability. These engines are the most compact and powerful in their class. The 24-valve overhead cam valve train is the main driver of this success. And, not to forget, the water cooled wastegated turbocharger, intercooler and fuel cooler, which maintain peak performance.

Yanmar's engines last and last. They are designed and built to do just that. Every detail is taken Into account. Take for instance the stainless steel exhaust/water mixing elbow: a guarantee for long life and corrosion resistance. This tough engine is built to perform. The turbocharger with wastegate and inlercooler improves acceleration on the higher output model even further. This is best-in-dass diesel power from Yanmar.

The basic design
The D6 is a 6-cylinder marine diesel engine with common rail high-pressure fuel injection, double overhead camshafts, 4 valves per cylinder, turbocharger and aftercooler. The displacement is 5.5 litres. It is extremely compact considering its large swept volume, high output and unique marine torque. Together with a large swept volume and the EVC system (Electronic Vessel Control), this results in world-class diesel performance, combined with low emissions.
|
|
In designing the engines, consideration was given to their intensive use and to the desirability of easy and simple maintenance. These engines feature individual cylinder heads and wide inspection doors in the block, which makes access to the inside parts of the engine easy, and shortens the service time during maintenance and repair processes.
This series comprises six and eight cylinder in-line engines as well as twelve and sixteen cylinder 60º V-bank engines.
- Reliable
- Efficient
- Economic maintenance
- Environmental-friendly
