| description | The present invention relates to: self-tuning engine control algorithms using inputs from transducers that measure pressure in the engine cylinders, and from an engine crankshaft rotational position sensor; methods of processing the input signals to "self-tune" or learn accurate values for a) pressure transducer voltage offset, b) crank position encoder error and c) engine compression ratio; improved pressure-ratio-based algorithms for calculating cylinder heat release fraction as a function of crank angle. |
