A stochastic model for the indicated pressure process and the dynamics of the internal combustion engine

Some of the research problems pertaining to cyclic combustion variability are reformulated from a perspective markedly different from the fluid dynamic and thermodynamic models which traditionally characterize this research: a system viewpoint is embraced to construct a stochastic model for the cylinder pressure process and the dynamics of the internal combustion engine. A deterministic model for the dynamics of the engine is briefly described, and a stochastic model is proposed for the cylinder pressure process. The deterministic model and the stochastic representation are tied together in a Kalman filter model. Experimental results that validate the models are discussed.<
