A R Peachment is the UK & Ireland distributor for Nanni Diesel marine engines and generators. Nanni Diesel supply engines from 10hp to 320hp and can be categorised as follows:
The John Deere Series
This year, 2015 has seen the introduction of new additions to Nanni Diesel’s already comprehensive range of diesel inboard engines. Nanni Industries has entered into a partnership with John Deere. A US company, John Deere has been developing high quality products since 1837 and Nanni Diesel’s recent addition to their engine range; the N6.405 (405hp) and N9.600 (557hp) are based on these John Deere engines.
The T4 Evo2 Series
The Evo2 series engines have been developed on the basis of the proven reliable Common Rail engine which is used on several Toyota four-wheel drive vehicles. The excellent power and torque in relation to the engines weight and compact size translate into clear advantages, for user and boat-builder.
Built with ratings specifically designed for marine applications, these engines deliver their torque at low rpm ensuring the boat lifts from the water and onto the plane quicker.
- Maximum torque and power with low rotation speed, making it possible to achieve a good cruising speed with low noise and vibration levels.
- Fuel economy.
- Highly developed Kubota technology, particularly in terms of compliance with anti-pollution standards.
- Easy maintenance.
- Excellent power-weight ratio.
- Higher rotation speeds.
- Employs latest technology in injection and supply systems.
Common Rail Toyota-based Engines – From 165hp to 200hp
In 2008 Nanni Diesel launched the common rail system, available on three of the engines from the Toyota range, the T4.165 (165hp), the T4.180 (180hp) and the T4.200 (200hp). Key benefits of this electronic injection management system include:
- Low noise & vibration levels.
- Excellent fuel economy.
- Environmentally friendly.
The common rail system stores fuel, which has been pressurised by the supply pump in the common rail. By storing fuel at high pressure, the common rail can provide fuel injection at a steady pressure, regardless of fuel speed or engine load. The ECU (Electronic Control Unit) provides an electric current to the solenoid valve in the injector, regulating fuel injection timing & volume. It also monitors the internal fuel pressure of the common rail using the fuel pressure sensor. The ECU causes the supply pump to supply the fuel necessary to obtain the target fuel pressure. In addition to this, the system uses a Two Way Valve (TWV) inside the injector to open and close the fuel passage. Therefore, both fuel timing fuel injection volume can be precisely regulated by the ECU. The common rail system gives two split fuel injections. In order to soften combustion shock, this system performs ‘pilot-injection’ as the subsidiary prior to the main fuel injection. This helps reduce engine vibration & noise.
Nanni Diesel Hybrid Engine – From 43hp to 200hp
In 2009, Nanni Diesel launched their Hybrid Engine. Suitable for the engine range from 43hp to 200hp, it is available in 24v (6.8hp) and 48v (9.5hp). It is environmentally friendly with zero emissions, silent & comfortable operating in electrical mode. It fits neatly between the engine flywheel and the gearbox, and requires very little maintenance. The principle behind this engine is based on a generator. The batteries are charged while the diesel engine is running. These in turn power the electrical propulsion when the diesel unit is not running. An electronic management unit independently controls the hybrid system to direct the energy to either charging the batteries or power the electrical engine. The main benefits are listed below:-
- Environmentally friendly, silent & comfortable in electric mode with zero emissions.
- Comfortable navigation and fuel efficient in electrical mode with total control, while cruising.
- Easy to control in electric & diesel mode, with a shared single lever control.
- Low maintenance – coupled between the engine flywheel & gearbox (no bracket adjustments).
- Easy to switch instantly between electric and diesel mode as required, for example, in strong winds and tidal conditions.
- Compliant with emission regulations (EPA, RCD and BSO).
