Bi-fuel systems can save operators up to 50 percent on fuel costs, based upon the cost of diesel relative to natural gas, and they make diesel engines more environmentally friendly.

All natural-gas engines take advantage of the fuel’s lower cost and lower output of regulated emissions than diesel fuel, but there are some key differences in the types of engines available ...

If a vehicle is equipped with an exhaust brake system, though, an additional valve is added to the inner workings of the exhaust pipes. This valve can be directly controlled by a switch on the ...
