Abstract: A power system includes a dual fuel engine, a first fuel source configured to provide a first fuel to the engine, and a second fuel source configured to provide a second fuel to the engine different than the first fuel. The power system also includes an exhaust system configured to receive combustion exhaust from the engine. The exhaust system includes a reduction catalyst comprising palladium catalyst material and an oxidation catalyst comprising cobalt catalyst material. Additionally, changing a ratio of the first fuel provided to the engine relative to the second fuel changes a NOx conversion efficiency of the reduction catalyst.

Abstract: A system and method for operating a combustion engine including a combustion chamber operable in at least a first operating mode and second operating mode. An engine control unit (ECU) performs conductivity sensing within the combustion chamber and interprets the results. Specifically, the ECU determines the current between a pair of spark plug electrodes placed within a combustion chamber of a combustion engine prior to, or after, combustion. The ECU determines whether the current between the pair of electrodes is indicative of spark plug fouling. If spark plug fouling is determined, the ECU can modify the mode of operation to correct the spark plug fouling and clean the deposits on the spark plug while the engine is in operation and without operation intervention.
