EXHAUST PARAMETER BASED DUAL FUEL ENGINE POWER VIRTUAL SENSOR

摘要

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.
