Developed to satisfy the most demanding Customer requirements, the NEF Series is the evidence of FPT Industrial technological excellence.
Available in 6 cylinders versions, NEF engines offer high power and load acceptance delivery with top-class levels of reliability and efficiency.
The NEF Series is offered either with mechanical or Common Rail injection.
mechanical versions, rotary pump guarantees accurate fuel delivery and best trade-off between performance and easy and fast service/maintenance operation.
• In electronic versions, Common Rail injection (up to 1,600 bar) allows the achievement of top performance with minimum fuel consumption.
NEF engines are available in naturally aspirated, turbocharged and turbocharged with aftercooler versions, that allow final users to optimize both engine installation and final Genset performance.
Options include hot part guards, water jacket heater, alarm senders, oil drain systems, front radiator guard. Thanks to their extraordinary design flexibility, all NEF engines are adaptable to market request.
NEF engines are certified ISO 8528 standard, G2/G3 class for excellent load acceptance. High thermodynamic performance and engine load response make these engines the best choice in all power generation applications.
Emission performance is achieved without external EGR, VGT or electronics Systems. Flexibility of use is enhanced by cold-starting temperature down to -25°C (with grid heater).
Extra-long oil change intervals (up to 800 hours with NEF mechanical versions) maximize engine uptime. Optimized combustion chambers and high-pressure injection system reduce oil dilution. Engine design is optimized in terms of mechanical clearances, piston rings and oil system calculation.
Compact size and high component integration facilitate engine installation (water-oil cooler, oil and water pumps are fully integrated in the engine block). This also reduces the risk of fluid leakage.
