Nanni Diesel N4.40

Engine base Kubota
This Nanni Diesel 4-cylinder, which is equipped with the latest Kubota innovations, is extremely suitable for so-called displacers and motor yachts.
Nanni Diesel has a solid partnership with Kubota. Kubota engines are known for their robust design, great reliability and long life.
The experience and knowledge of the Nanni Diesel engineers resulted in the latest marinization developments that benefit the N4.40. The heat exchanger ensures an ideal temperature control of the engine even in intensive use.
Reliability and low maintenance costs are justified by the gear distribution and other solid designs of the Kubota engine base.
Environmental – Tri Vortex combustion system (E-TVCS)
The Nanni N4.40 is equipped with the E-TVCS combustion/injection system with a significantly reduced emission of soot particles and smoke, while dramatically improving fuel consumption.

Ease of use
The low nominal speed of 2800 rpm in combination with the high engine power gives the N4.40 enough power for all navigation conditions.
The N4.40 meets the most stringent emission requirements in the world: RCD 2013/53/EU EPA marine Tier 3 BSO 2.
