Dual Fuel Conversion kits (also known as bi-fuel Conversion kits) enable diesel engines to run on a mixture of natural gas and diesel fuel. This enable cheaper power generation, a cleaner environment and longer generator life because natural gas is a much cleaner fuel than diesel. Practical tests have revealed that the internal condition of an engine operating on dual fuel remains much better than when it is being operated only on diesel fuel. Engine life is prolonged and the time between overhauls can be increased. Dual Fuel operation also minimizes problems associated with cartage, storage and handling of large volumes of diesel fuel. Equally importantly, the many advantages of diesel engines are retained in their entirety.
Dual-Fuel conversion kits are also available for vehicular installations. These are complex devices but they enable conversion of diesel engined vehicles to burn clean and cheap natural gas.
