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 EPA Tier 3 and EU
stage III A exhaust emissions regulations.
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, electronically governed MP type fuel
injector 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.
