Abstract: Systems, methods and apparatus for controlling operation of an engine structured to combust gaseous fuel such as a dual fuel engine, including an estimation of key parameters dependent on natural gas quality, are disclosed. The natural gas quality parameters are estimated from natural gas properties obtained from various sensed parameters associated with the engine.

Abstract: The system comprises a fuel description module structured to provide a first signal, and a control circuit operable to receive the first signal. The fuel description module comprises a fuel consumption detection package. The fuel consumption detection package an intake manifold temperature sensor and an exhaust temperature sensor, wherein the first signal corresponds to a difference between the exhaust manifold temperature (EMT) and the intake manifold temperature (IMT). The control circuit is responsive to the first signal to produce a second signal indicating a total energy content (Efuel) of fuel supplied to the dual-fuel engine. The Efuel value indicating the total energy content provided to the engine from a first fuel and a second fuel.

Abstract: Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.
