TNV Series liquid-cooled diesel engines replace the Clean & Silent TNE Series. The new series consists of the smaller, indirect-injection 2TNV70 and 3TNV70/76 with rated horsepower of 14.3, 21.9 and 25.0, respectively. Improvements to combustion and FIE systems result in cleaner combustion through refined air-intake design. An in-line fuel-injection pump provides the same level of FIE performance as in the company's direct-injection engines. A load timer adjusts injection timing in accordance with the engine load.
