Features


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 TNM engines now proudly take up the running as YANMAR’s premium small industrial diesel. They offer even more enhanced durability due to better block cooling, a stiffer crank and pistons, finer tolerance in the journal and more. CAE analysis has brought lower vibrations and higher strength to the mounting structure for even better reliability in heavy-duty jobs.

Fuel Delivery and Economy

YANMAR has refined 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, assuring that Yanmar’s reputation for superior starting characteristics continues.

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.
