WODAUSCH, J. et al. Auto-ignition Prediction During Hot Start Conditions. R&D j. (Matieland, Online) [online]. 2010, vol.26, pp.53-57. ISSN 2309-8988.

This paper describes the development of an empirical thermodynamic single-zone model to predict auto-ignition in an internal combustion engine. In this case the development basis is a 1.4 L multi port injection (MPI) internal combustion engine. A model was created to calculate the probability of auto-ignition with regards to the engine design, thermodynamic laws and the carbtiretion of the air-fuel mixture. The theoretical model developed was verifíed with measurements. Adequate correlation between the predicted and measured probability results was obtained.

Keywords : Knack detection modelling.
