Abstract
A power system includes an intake arrangement configured to intake charge air; a fuel arrangement configured to store a blend of methane (CH4) and hydrogen (H2) fuel; an engine configured to receive, ignite, and combust a mixture of the charge air and the blend of methane (CH4) and hydrogen (H2) fuel; and a controller coupled to selectively command such that, in a first mode, the controller commands the one or more of the intake arrangement, the fuel arrangement, and the engine such that the charge air and the blend of methane (CH4) and hydrogen (H2) fuel are introduced at a stoichiometric equivalence ratio; and in a second mode, the controller commands the one or more of the intake arrangement, the fuel arrangement, and the engine such that the charge and the blend of methane (CH4) and hydrogen (H2) fuel are introduced at a lean equivalence ratio.
