Self tuning cylinder pressure based heat release computation

Tunestål, Per LU (2007) 5th IFAC Symposium on Advances in Automotive Control In Proceedings for the 5th IFAC Symposium on Advances in Automotive Control p.183-190
Abstract
The paper describes a novel method for self tuning cylinder pressure

based heat release computation that is suitable for online usage in e.g. combustion

phasing control applications. The method estimates the polytropic exponents and

cylinder pressure offsets immediately preceding and succeeding the combustion

event respectively using a fast nonlinear least squares method. The polytropic exponent

and the pressure offset is subsequently interpolated during the combustion

event and a net heat release computation is performed based on the interpolated

exponent and pressure. The result is a self tuning heat release algorithm with no

need to model heat losses, crevice losses... (More)
