Abstract
Systems and methods to enable efficient flex fuel operation with fuel blends including natural gas and hydrogen. The system includes a fuel storage system fluidly connected to an engine, the engine having an air handling system connected to a downstream side of the engine by a main exhaust passage, and an oxygen sensor interfacing with the main exhaust passage. The system also includes a controller configured to perform methods including performing a fuel identification routine to determine a composition of fuel blend at startup of the engine, determining target operating conditions corresponding to the composition of the fuel blend for operation of the engine, use the oxygen sensor to measure a residual oxygen concentration in an exhaust gas stream, calculate an operating air-fuel ratio, and adjust engine operating conditions until the operating air-fuel ratio equals the target air-fuel ratio.
