Features
Clean Emissions
Building off the proven TNE design, Yanmar has
achieved superior exhaust emissions by improving the
combustion chamber and fuel injection equipment
design. Engines are compliant with 2008 EPA Tier 4.
Reliable and Durable
The TNV 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
A newly designed, in-line ML fuel injection pump is
utilized to assure more precise fuel delivery and control.
The result is reduced emissions, improved performance
over a wide range of applications and good fuel
economy which assures 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.
