Neural Network Control of a Bi-Fuel Engine 2004-01-1360

This paper describes the design of an intelligent control strategy that would allow the conversion of a gasoline engine to a bi-fuel form with minimal alteration. Conversion of a conventional gasoline engine to a bi-fuel form is easy and can be achieved at a relatively low cost. By using a bi-fuel engine in vehicles, the advantages of both natural gas and gasoline can be exploited. When the natural gas tank empties, the vehicle can be operated on gasoline until it is refueled with natural gas.
This paper describes an add-on control module that is developed and applied to an engine for bi-fuel operation. The control scheme uses neural networks and is capable of substantially improving the operation of a bi-fuel engine in terms of emissions. Simulation results are reported.
