Clean Emissions
Building off the proven TNV design, YANMAR has achieved superior exhaust emissions by improving the combustion chamber and increasing the displacement and compression ratio. YANMAR engines meet the strict NTE and NRTC test requirements for 2014 Final Tier 4.

Reliable and Durable
The new line of Final Tier 4 engines continues to build upon the legendary reliability of the YANMAR TNV line with a focus on vibration reduction and higher-strength materials. The result is an engine more than capable of handling the most demanding applications.

Fuel Delivery and Economy
YANMAR continues its reputation for superior starting characteristics by refining the combustion process to assure more precise fuel delivery and control. The result is reduced emissions, improved performance over a wide range of applications and increased fuel economy.

Noise Level Reduction
YANMAR’s original CAE techniques have optimized the stiffness, minimized transformation and reduced radiant noise in the cylinder block. Gear noise reduction is achieved through an improved gear tooth profile resulting in less mechanical noise.
