Welcome to a new level of performance

The smaller Indirect Injection (IDI) engines have been made more efficient with the Yanmar Research Team improving engine combustion by altering flow mixing of air and fuel while a new, more compact in-line fuel injection pump has been developed for the TNV Series for faster fuel control and lower emissions.

The larger Direct Injection (DI) engines have also seen a makeover. Uneven atomisation of fuel in the combustion chamber has been reduced by changing the angle of the injector nozzle. A greater swirl effect in the combustion chamber has been achieved to increase the fluid energy of the air and fuel charge plus a new MP fuel injection pump delivers high injection pressure and more even injection between the cylinders. Engine noise has also been minimised with an optimised cylinder block and muffler design.


YANMAR continues its reputation for superior starting characteristics by refining the combustion process to assure more precise fuel delivery and control. The result is reduced emissions, improved performance over a wide range of applications and increased fuel economy.
