Description
The NEF Series is the most compact, efficient and cost-effective engine solution in the 6 to 18 tons truck, bus and coach category.
The NEF family includes by a 6-cylinder, 6-liter CNG version that offers un paired sustainability.
Natural gas is the most eco-friendly fuel for internal combustion engines, capable of bringing significant environmental advantages:
• it improves
local air quality nearly eliminating air pollutants,
• it mitigates
global warming by significantly reducing CO2 emissions
• and it significantly lowers
engine noise.
These eco-benefits come together with a competitive TCO – thanks to the well-tested reliability and fuel economy of our natural gas technology. As all NEF engines, this can be customized upon demand with a rich set of options.
Thanks to latest-generationCommon Rail injection, waste-gate turbocharger and no-EGR architecture, NEF engines ensure optimal combustion efficiency – resulting in low fuel consumption and high performance (+5% power density vs market average). The regeneration-free HI-eSCR system avoids unplanned stops (especially in indoor, sensible environments).
Up to 80.000 km oil change intervals allow a substantial reduction in downtime and fluid cost. The FPT Industrial-patented HI-eSCR system makes regeneration unnecessary, so reducing thermal stress and maintenance needs.
Both NEF engines and the HI-eSCR system are characterized by compact and lightweight design. Our EGR-free technology requires less cooling power (and thus a smaller cooling package size), also simplifying vehicle application. In order to further facilitate installation, a wide choice of customized after-treatment layouts is available.
Our exclusive HI-eSCR after-treatment system represents a “fit & forget” solution that ensures best durability and lowest operating costs. This technology relies on long-standing and proven SCR experience, based on more than 650,000 units produced by FPT Industrial since 2005.
