Yanmar Introduces New Range of EPA Tier 4 Compliant Diesel Engines

Monday, January 23, 2012 

ADAIRSVILLE, Ga.  – Yanmar America today announced that it is introducing water- cooled industrial diesel engines fully compliant with the new EPA Tier 4 and EU Stage IIIB off-highway emission regulations, based substantially on its TNV series. There are 10 models in total, a mix of three and four cylinder diesels, indirect and direct injection and ranging from 10kW to 56kW.

 

The full list comprises the Yanmar indirect injection 3TNM74F, 3TNV74F and 3TNV80F, plus the direct injected 3TNV88F for the range of under 19kW, and 3TNV88C, 3TNV86CT, 4TNV88C, 4TNV86CT, 4TNV98C and 4TNV98CT for over 19kW. Three of these new EPA Tier 4 engines, the 3TNV88F, 3TNV86CT and 4TNV88C will be shown at World of Concrete 2012 in Las Vegas.

 

All are interchangeable with existing Yanmar engines and comply in full with relevant emissions regulations, including EPA limits and use at high altitudes.

 

For over 19kW, clear diesel engine technologies taken by Yanmar to comply with the latest emissions regulations have included use of an ECU-controlled Common Rail fuel injection system, water-cooled exhaust gas recirculation (Cooled EGR), a new intake throttle valve and diesel particulate filter (DPF). Yanmar’s original filter regeneration is controlled by different regeneration patterns, selected according to the operational period and load conditions involved.

 

This DPF regeneration control enables Yanmar to achieve extremely low lube oil dilution by fuel oil and lower fuel consumption overall. Also, the remarkable reduction of lubrication oil consumption leads to extended DPF durability and longer maintenance intervals.

 

In addition, there is 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 will be introduced shortly. In 1996, Yanmar became the first manufacturer to have a diesel engine certified under the EPA process. The latest emissions standards have significantly lower limits.  For example, EPA Tier 4 and EU Stage IIIB require a 90 percent reduction in particulate matter compared to the previous measure.

 

Yanmar’s new engines comply with the latest emissions regulations by utilizing the most advanced technology combined with Yanmar’s 100 year legacy of superior diesel engine expertise.
