Abstract
An engine system and method for operating an internal combustion engine in dynamically varying conditions. An exemplary system comprises an internal combustion engine configured to receive both a primary fuel and a secondary fuel into one or more chambers in which a combustion process occurs, a fuel injection system, an air intake manifold and a fuel manifold; an electronic system which controls timing and metering of the primary fuel and/or the secondary fuel in the combustion process; and a plurality of sensors positioned to measure one or more variables associated with combustion of the primary fuel in the presence of the secondary fuel. The electronic system is configured to apply a control signal to adjust an engine setting to reduce NOx emissions based in part on the magnitude of the variable.
