Designed for sailing yachts as well as sport fishing boats, the N4.80 is a 4 cylinder diesel engine with direct fuel injection. It benefits from the experience of the Nanni Diesel engineering team in terms of marinization and from the latest technological developments by Kubota for their industrial engine bases.
The E-CDIS direct injection system equipping the N4.80 is characterized by an injector positioning in the centre of the 4 valves per cylinder. This technology results in considerable reduction of particulate emission. Its low rated rpm of 2800rpm associated with the direct injection offers you ease of use and important fuel efficiency.
The reduced dimensions of the N4.80 engine allows it to be installed in the smallest engine compartments. The large choice of straight or angle down gearboxes, either mechanical or hydraulic, as well as a Sail Drive transmission allows you to fully utilize the significant torque of this engine by perfectly adapting it to your specific vessel. As a result of its 2.5 liter cylinder capacity and the characteristics of its turbocharger, the N4.80 develops high torque at low rpm. The take-off is faster and cruising speeds are reached at lower rpm levels. Its two balancing shafts driven by a gearwheel distribution bring robustness and reliability to the engine, while easing its maintenance.
The N4.80 complies with the most stringent emission regulations in the world: EPA marine Tier 3, RCD2013/53/EU, BSO2
