Yanmar's addition to the TNV family

Yanmar is set to add three new turbocharged and aftercooled engines to its range, joining the company's existing TNV family of common rail engines which are EPA Tier 4 final, EU Stage 3B and FOEN (Switzerland) certified.

The engines have already found favour with construction equipment manufacturers, especially for excavator and wheeled loader applications because of their lower fuel consumption, higher power density and a diesel particulate filter which practically needs no maintenance.

The new 1.6, 2.1 and 3.1 litre engines feature Bosch and Denso common rail direct fuel injection systems, full authority electronics and rated powers ranging from 33.3 to 88.4 kW

With the addition of the turbocharged, aftercooled engines, the TNV CR engine range now consists of nine models.

"This is a major addition to the TNV range offering a host of benefits to equipment makers, not least enhanced fuel efficiency and compactness, requiring less space for installation than equivalent engines with the same output," says Gert Maris, Senior Area Manager, Industrial Power Train Department, Yanmar Europe.

"Another key benefit is that, through Yanmar's unique exhaust gas management technology for the diesel particulate filter, extremely long maintenance intervals of 6,000 hours - effectively, the lifetime of most machines - can be achieved, thus eliminating operator downtime."

The three new engines are the three-cylinder 3TNV86CHT (33.3 kW at 2,600 rpm); four-cylinder 4TNV86CHT (48.5 kW at 2,600 rpm) and the four-cylinder 4TNV94FHT (69.8 kW at 2,000 rpm, 77.2 kW at 2,200 rpm and 88.4kW at 2,500 rpm).
