Self tuning cylinder pressure based heat release computation
(2007) 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) - The paper describes a novel method for self tuning cylinder pressure
