This Kubota based engine combines high quality and reliability with the latest diesel technology.  Kubota’s new DI version of the V3 series incorporates a new four-valve per cylinder head with a new injection system, the E-CDIS.  This system, with an injector located in the centre of each cylinder, drastically improved fuel efficiency.

Thanks to the maximum torque at only 1600rpm, the N4.115 gives an exceptionally low level of noise & vibration.

The half float structured head cover successfully reduces the radiating noise from the upper part of the engine.  Moreover, the MoS2 coated piston and the three step open thermostat help reduce piston slap by optimising piston/cylinder wall clearance as the engine coolant comes up to temperature.  The built-in twin balancer helps to reduce vibration even further.
