Abstract: An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler (“CAC”), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.

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.
