Attachment of cylinder heads on cylinders block by high strength steel bolts
2 valves per cylinder with built up guides and seat
Special forged steel crankshaft, 7 bearings, with integrated counter weights and hardened journals and connecting radius
Camshaft side mounted in cylinder block
Distribution system with tempered special steel gears

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.

CHARACTERISTICS
Diesel engine, 4 stroke, direct injection, naturally aspirated.
