Bi-fuel is the term used to describe a vehicle or its fuel system. It essentially means that it can operate on two fuels. An Autogas bi-fuel vehicle is a conventional gasoline vehicle that can run on both Autogas and gasoline.
The primary advantage of a bi-fuel system over a dedicated or “monofuel” system is that there are no restrictions to the use of the vehicle based on fuel capacity and that the vehicle has increased range.
If there is any issue with the operation of a Dedicated or Monofuel Autogas system, the vehicle becomes inoperable, whereas with a Bi-fuel system, the vehicle can operate on gasoline when desired.
Also, in the event that a driver has traveled out of range of an Autogas refueling station, the vehicle is capable of running on gasoline with the push of a button.
