Yanmar introduces new range of Tier 4 diesel engines

Yanmar America announced a new range of water-cooled industrial diesel
engines compliant with EPA Tier 4 and EU Stage IIIB nonroad emission
regulations. The new range, based substantially on Yanmar TNV series,
includes 10 models in total--a mix of three and four cylinder diesels
(indirect and direct injection) ranging from 10 kW to 56 kW.

The full list comprises the Yanmar indirect injection models 3TNM74F,
3TNV74F and 3TNV80F, and the direct injected 3TNV88F for the range of
under 19 kW, and 3TNV88C, 3TNV86CT, 4TNV88C, 4TNV86CT, 4TNV98C and
4TNV98CT for over 19 kW. All of the new models are interchangeable
with existing Yanmar engines.

For over 19 kW, the engine technologies chosen by Yanmar include the
use of an ECU-controlled common rail fuel injection system, water-
cooled exhaust gas recirculation (EGR), a new intake throttle valve
and diesel particulate filter (DPF) with active regeneration. The DPF
regeneration control enables to "achieve extremely low lube oil
dilution by fuel oil and lower fuel consumption overall," said Yanmar.
The reduction of lubrication oil consumption also leads to extended
DPF durability and longer maintenance intervals.

Yanmar also announced a new electronic control diagnostics service
system, Yanmar's SA-D, short for SMARTASSIST-Direct. A remotely-
monitored system, Yanmar's SA-R (SMARTASSIST-Remote), to confirm the
real-time engine running status and offer timely technical services is
to be introduced shortly.
