Abstract

A turbulent entrainment burning model is considered to be a reasonable one for the combustion in a spark-ignition engine. The concept is based on the Blizard and Tabaczynski model. It is important to estimate the turbulence characteristics, turbulent burning velocity, flame surface area and several experimental constants. Nevertheless, the examination of these values are insufficient, regardless of using many assumptions in previous studies. In this study, turbulence characteristics, the initial stage of burn duration and turbulent burning velocity were discussed in detail. This model was examined under various conditions of engine speed (600-1200 rpm), compression ratio (3.2-4.8) and ignition timing. The calculation results of mass fraction burned, burn rate and burn duration were in good agreement with the experimental ones. It was found that this model was valid for predicting the combustion in a spark-ignition engine.
