N45

  • Compact and cost-effective

  • Short load response time

  • Top power with minimum fuel consumption

  • Up to 800 hours service intervals

Developed to satisfy the most demanding Customer requirements, the NEF Series is the evidence of FPT Industrial technological excellence.

Available in 4 cylinders versions, NEF engines offer high, constant power and torque delivery with top-class levels of reliability and efficiency.

The NEF Series is offered with mechanical injection and the rotary pump guarantees accurate fuel delivery and best trade-off between performance and easy and fast service/maintenance operation.

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, alar​m senders, oil drain systems, front radiator guard. Thanks to their extraordinary design flexibility, all NEF engines are adaptable to market request.

Features & benefits

NEF engines are certified ISO 8528 standard, G2/G3 class for excellent load acceptance. High thermodynamic performance and engine 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.
