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 unpaired 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.
NEF natural gas engines deliver high power and torque output, with any load and on any route compared to Diesel.
Fuel cost savings vs Diesel amount to up to 30%. Moreover, natural gas is significantly less expensive than Diesel in most European Countries.
A simple and easy to install 3 way catalyst Is enough to reach Euro VI standards: the emission level of natural gas-powered vehicles is significantly lower compared to Diesel, and can reach near zero by using bio-methane.
