On the effect of temperature and the width of the turbulent combustion zone on the ionization detector readings

We have considered the functional dependence of the ionization detector readings (ion current) on the composition of the fuel–air mixture, adiabatic temperature, and the turbulent combustion zone width. Experiments on the engine show that, for an air excess factor of 0.75–1.15, the coincidence of the calculated and experimental data exceeds 90%. Our results can be used to predict and monitor the adiabatic temperature of the flame and the width of the turbulent combustion zone in the combustion changer of the internal combustion engine using the ionization detector.
