Abstract
A bi-fuel internal combustion engine system includes a first fuel system, a second fuel system, and a bi-fuel internal combustion engine. The bi-fuel internal combustion engine is configured to selectively consume one of a first fuel received from the first fuel system and a second fuel received from the second fuel system. The bi-fuel internal combustion engine includes a camshaft and a valve assembly. The camshaft has a cam. The valve assembly is positioned adjacent the camshaft and configured to interface with the cam. The valve assembly is selectively repositionable between a first position and a second position. The bi-fuel internal combustion engine has a first dynamic compression ratio when the valve assembly is in the first position and a second dynamic compression ratio when the valve assembly is in the second position. The second dynamic compression ratio is greater than the first dynamic compression ratio.
