The article presents the results of an analytical review of the major conventional approaches to processing and analysis of the ion current signal of contemporary domestic and foreign authors. Analysis of works made in terms of assessing the possibility of calculating the parameters of the combustion of the fuel-air mixture. It is shown that strong susceptibility of ion current to influence of intercyclic variations limits application of methods in practice, despite considerable theoretical opportunities of such methods.

In article the comparative analysis of various versions of circuitry solutions of realization of devices of registration of ionic current, is made, theoretical justification of almost known advantages and shortcomings of the considered devices. In article are given the experimental data obtained at registration of a signal of ionic current by various devices. Is made processing of oscillograms and shown qualitative advantage of the device of registration of ionic current with the stabilized boost converter for the solution of problems of registration of a signal of ionic current with increased requirements to quality of a signal.
