ABSTRACT
The ionization signal, which is a result the presence of ions and electrons in the cylinder space of the internal combustion engine,
is affected by many factors, including: temperature, pressure, fuel mixture composition, fuel type, presence of exhaust gases and
others. The shape of the signal changes to a large extent from cycle to cycle, which indicates the stochastics of the combustion
process. Nevertheless, its analysis provides a lot of useful information, such as the location of the maximum pressure or the maximum heat release rate. Using these signals allows supplementing the limited engine control systems of the combustion process in
internal combustion engines. The paper presents a comparative analysis of the gas ionization current signal in the cylinder and the
variable pressure at fixed operating points of a single-cylinder, four-stroke engine powered by natural gas. The analysis allowed to
determine the relationship between the positions of the maximum thermal ionization signal value and of the maximum combustion
pressure value. Additionally the relationship between the position of the maximum thermal fraction derivative and the maximum
heat release rate was established.
