Yanmar TNV Series under 19 kW – water-cooled industrial diesels of the register: 3TNV80F-Z and 3TNV80FT, three-cylinder units in the EU Stage V category NRE-v/c-1/2
The Yanmar TNV Series in the power class under 19 kW brings together on this collective page two water-cooled industrial diesel engines: 3TNV80F-Z and 3TNV80FT. Yanmar was founded in 1912 in Osaka; in the type designation of the TN engine family, the leading digit denotes the number of cylinders, so both TNV engines listed here are three-cylinder units, with the two versions differing among other things in their turbocharging.

The register lists here two versions, 3TNV80F-Z and 3TNV80FT, each with 18.4 kW or 25.0 hp, 1,266 cm³ displacement and 124 kg dry weight; rated speed is 2,800 rpm for the naturally aspirated version and 2,600 rpm for the turbocharged version. Both meet the EU Stage V and EPA/CARB Final Tier 4 emission standards.
The TNV range is among Yanmar's most widely fitted industrial diesel engines and drives construction machinery such as mini excavators and compact loaders, generator sets, pumps and compressors; such small non-road engines under 19 kW fall under the EU Stage V category NRE-v/c-1 or NRE-v/c-2 and are therefore subject to their own emission limits compared with more powerful industrial engines, which matters when choosing a replacement engine for older machines.
When buying used, what counts on these three-cylinder engines is the condition of the turbocharger and charge-air ducting on the turbocharged version, the tightness of the cooling system, and compression and oil consumption; on compact construction machinery fitted with these engines it is also worth checking the condition of the hydraulic connections around the engine bay. Spare parts run through Yanmar's industrial engine distribution.
