A first control system for an engine includes first and second control modules. The first control module determines first and second fuel masses for first and second fuel injection systems of the engine, respectively, and that controls the first fuel injection system to inject a first fuel based on the first fuel mass. The second control module controls the second fuel injection system to inject a second fuel based on the second fuel mass. A second control system for an engine includes first and second control modules. The first control module controls a first fuel injection system of the engine to inject a first fuel and selectively disables at least one of a plurality of components of a second fuel injection system of the engine. The second control module controls the second fuel injection system to inject a second fuel.

An internal combustion engine includes an exhaust gas feedstream flowing past a gas sensing device disposed therein. The gas sensor includes an integrated electrical heating element which provides a resistance indicative of its temperature. An unknown input observer is used to determine the exhaust gas feedstream temperature based on the heating element temperature.

摘要:
A system for a vehicle includes a filtering module, an indicated mean effective pressure (IMEP) determination module, and a stuck mechanism indicator module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The IMEP determination module determines an IMEP for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds during the combustion cycle. The stuck mechanism indicator module selectively diagnoses a fault in a variable valve lift (VVL) mechanism of the cylinder based on the IMEP.

A system for a vehicle includes a filtering module and an indicated work module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The crankshaft position sensor generates the crankshaft position signal based on rotation of the toothed wheel. The indicated work module generates an indicated work for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds and outputs the indicated work.
