Propane for Bi-fuel Power

Get the most from your diesel engine - convert to a dual fuel power system

Substituting diesel fuel with low cost, low emission propane enables engines to run on a diesel/propane mix that substantially reduces your operating costs and maintenance requirements. Dual fuel or bi-fuel engines operate at a lower temperature and require less fuel per load, resulting in less maintenance and longer engine life. Engines converted to bi-fuel with propane replace up to 40% of diesel fuel requirements without engine interruption.

How it works
