Landi Renzo USA announced it has received EPA approval of a dual-fuel (diesel and natural gas) engine. The remanufactured powerplant is a pre-EGR Detroit Diesel S60 12.7L engine.

The dual-fuel system injects natural gas after the turbo/intercooler and a computer controls the exact balance of natural gas and diesel fuels, to achieve the maximum performance, efficiency and economy, Landi Renzo said.

This engine runs on compressed natural gas, which replaces the majority of diesel fuel usage for an average fuel displacement of up to 60% and noise reduction of up to 40%.

The dual-fuel engine reduces particulate matter by up to 40%, CO2 up to 14% and 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,” said Andrea Landi, president.

Benefits of the engine include:

  • 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

Landi Renzo SpA is the world leader in the alternative fuel industry, serving more than 30% of the global market for LPG and CNG solutions. Established in 1954, Landi Renzo began exporting its products throughout Europe in 1963 after national sales grew rapidly. Since then, it has expanded in the Eastern European, Indian, and South American markets with new branches opening in Brazil in 2003 and China in 2005.
