top of page What about efficiency?
As explained above, GTI’s Bi-Fuel System replaces diesel fuel with an equivalent quantity of natural gas. This process results in the same net fuel burn vs. load as would be experienced during 100% diesel operation. For each gallon of diesel fuel displaced during Bi-Fuel operation, there is a corresponding consumption of approximately 140 cubic feet of pipeline quality natural gas (based on 129,000 btu/gallon # 2 diesel & 930 btu/scf natural gas). Thus, for each gallon of diesel fuel displaced during Bi-Fuel operation, an “equivalent gallon” of natural gas is consumed resulting in similar engine fuel efficiencies. Note: 1 d of natural gas = I liter # 2 diesel. top of page What effect will GTI’s System have on the durability of my engine? Generally speaking, operation in Bi-Fuel mode has no negative effects on engine wear rates and durability. As explained above, because engine thermal loads are equivalent to 100% diesel operation, no excess wear of combustion chamber components (piston
