EPA Approval Of Dual Fuel CNG System for Detroit Diesel 12.7L S60 Engine

 Dual Fuel Detroit Diesel S60

Landi Renzo USA, a leading provider of automotive natural gas systems, announces EPA OUL approval of its dual fuel (diesel and natural gas) system for factory re-manufactured Pre-EGR Detroit Diesel S60 12.7L engines, for heavy duty trucks.


This advanced dual fuel system was developed over a twenty year period through Landi Renzo’s in-house engineering and technical team and allows operators of over the road trucks to take full advantage of the environmental and economic benefits of natural gas as a transportation fuel.  The latest generation Landi Renzo dual fuel system injects natural gas after the turbo/intercooler and computer controls the exact balance of natural gas and diesel fuels, to achieve the maximum performance, efficiency, and economy.

With a growing network of CNG (Compressed Natural Gas) stations throughout the U.S., this proprietary system allows operators to displace the majority of their diesel fuel usage with natural gas, resulting in:

  • Average fuel displacement up to 60%
  • Noise reduction up to 40%
  • Particulate matter reduction up to 40%
  • CO2 reduction up to 14%
  • Smoke reduction up to 50%

“As a world leader in alternative fuel systems, we are pleased to present the availability of this innovative technology. Not only does this expand our current clean fuel product offering, but also it further promotes the increased use of natural gas as a fuel and moves us further down a path of energy independence in the United States” says Andrea Landi, Landi Renzo USA President.


  • Performance comparable to the original Pre-EGR engine in terms of torque, horsepower, drivability, and economy
  • Maintains and improves the emission levels of the original engine
  • Flexibility for adaptation to different diesel engines
  • Ability to switch back to 100% diesel if needed
  • Requires less CNG storage compared to a dedicated CNG vehicles
  • Extended range compared to original diesel system

Nationwide, natural gas is available at over 1,200 stations and priced up to $2.00/gallon LESS than diesel fuel. In the event natural gas is not readily available, the engine automatically reverts back to 100% diesel operation.

While this specific dual fuel CNG system is new to the U.S. market, Landi Renzo has successfully deployed this technology globally on applications that include Fiat, Mercedes-Benz, Volkswagen, Ford, Hyundai and Renault diesel engines.  Take the opportunity to experience the latest dual fuel CNG technology.
