Under the Clean Alternative Fuel Vehicle and Engine Conversions (CAFC) rule of the Environmental Protection Agency’s Outside Useful Life (OUL) program, commercial vehicles and engines can be converted or replaced with cleaner, more modern alternatives and receive EPA compliance as clean vehicles.

Under this rule, EcoDual has received EPA compliance approval for its natural gas conversion system for Cummins ISX engines of model years 2004 to 2009.  These are the most common heavy-duty diesel engines in use in North America and the EcoDual conversion permits them to run on up to an 85:15 natural gas to diesel mixture.

This mixture allows the engine to maintain full torque and power without losing any miles per gallon when running on diesel only (which the engines remain capable of doing).  Fuel cost savings, however, are huge with natural gas being an average of 50% cheaper than diesel fuel nationally.

This is one small step towards a clean-fuel alternative that is much cheaper and simpler to install compared to other, more complex hybrid and similar alternatives.  It is a per-truck savings, so it can scale from a fleet of one to hundreds of trucks with the same expected savings per vehicle.
