Yanmar TNV Series

The TNV range is the engine that runs in the mini excavators, skid steers, compact tractors and generator sets of almost every maker: Yanmar of Osaka supplies it to Kubota's rivals such as Kobelco, Takeuchi, Case, New Holland, John Deere, Hitachi and Komatsu, as the register rows of those brands prove. The type code is a formula: the first digit gives the cylinder count (2, 3 or 4), TNV the engine family, the number the bore in millimetres – 70, 76, 82, 84, 88, 94, 98 and 106 – an appended T the turbocharger, Z, L and A version and emission variants. A 3TNV88 is therefore a three-cylinder with 88 mm bore, a 4TNV98T a four-cylinder with 98 mm bore and turbo. The range appeared in the 2000s as successor to the TNE engines and met EPA Tier 3 and 4 and EU Stage IIIA to V with direct injection.
