摘要: 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.

摘要: A fuel injection method for internal combustion engines with gasoline direct fuel injection systems comprises receiving a crankshaft position signal from a crankshaft position sensor. A position of a crankshaft is determined from the crankshaft position signal. Fuel is commanded at a first rate when the position of the crankshaft is within a first selectable range during a combustion cycle of an engine cylinder and fuel is commanded at a second rate when the position of the crankshaft is within a second selectable range during the combustion cycle of the engine cylinder.
