Summary: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. Un sistema de motor y método para operar un motor de combustión interna en condiciones dinámicamente variantes. Un sistema ejemplificativo comprende un motor de combustión interna configurado para recibir tanto un combustible primario y un combustible secundario en una o más cámaras en las que se produce un proceso de combustión, un sistema de inyección de combustible, un colector de admisión de aire y un colector de combustible; un sistema electrónico que controla el tiempo y la medición del combustible primario y / o el combustible secundario en el proceso de combustión; y una pluralidad de sensores colcoados para medir una o más variables asociadas con la combustión del combustible primario en la presencia del combustible secundario. El sistema electrónico está configurado para aplicar una señal de control para ajustar una configuración de motor para reducir las emisiones de NOx basándose en parte en la magnitud de la variable.
