This paper is concerned with the development of a simple
physical model of a gasoline engine cycle where the
energy release is via Controlled Auto-Ignition. It uses simple
thermodynamic concepts, and well-established gas exchange
and heat transfer sub-models to predict the pressures
and temperatures in the engine cycle. The combustion
event itself is modelled in a semi-empirical fashion.
The model is an important extension of existing single-zone
models and it persists between multiple cycles, enabling
the capture of the cycle-to-cycle exhaust gas coupling. The
model was compared with data obtained at steady engine
running conditions, and good agreement was found. Controlled
Auto-Ignition was attained by diluting the mixture
with exhaust gas trapped in the cylinder, as a result of an
early Exhaust Valve Closing.
