Interconnection of ion current with carbon concentration in fuel and the apparent propagation velocity of flame

Abstract

The article experimentally proves the interconnection of ion current with a carbon concentration in fuel and apparent propagation velocity of the flame. This confirms the hypothesis about the strong influence of rate of radical CH + formation on ion current and allows the use of its amplitude to determine characteristics of flame propagation, which greatly simplifies and reduces the cost of existing research methods using ionization probes of combustion process in piston engines.
