Yanmar TNE Series – water-cooled four-cylinder diesel engines of the register: 4TNE92, 4TNE94L and 4TNE98, an older generation of Yanmar industrial engines
The Yanmar TNE Series brings together on this collective page three water-cooled four-cylinder diesel engines: 4TNE92, 4TNE94L and 4TNE98. The leading 4 denotes the cylinder count; the TNE range belongs to an older generation of water-cooled compact diesels in Yanmar's industrial engine programme. Yanmar was founded in 1912 in Osaka and builds its industrial engines partly at its plant by Lake Biwa.

The register lists here 3 versions: 4TNE92, 4TNE94L and 4TNE98. Output ranges from 33.9 to 42.1 kW (46.1 to 57.2 hp) at displacements of 2,659 to 3,318 cm³ and rated speeds between 2,200 and 2,450 rpm; all three are water-cooled naturally aspirated four-cylinder engines, dry weight lies between 220 and 225 kg.
Water-cooled four-cylinder compact diesels such as the TNE range have driven and still drive mini excavators, compact loaders, forklifts and generator sets, offering more power with smoother running than three- and single-cylinder engines.
When buying used, what counts on these older four-cylinder engines is the condition of the radiator and water pump, compression, the condition of the injectors, and the tightness of the cylinder head gasket and oil pan; on this older engine generation it is especially worth checking spare parts availability before buying. Spare parts run through Yanmar's industrial engine distribution and through the makers of the equipment fitted with them.
