Combustion processes and the state of gases in a divided chamber

The mechanism of combustion in a chamber with an auxiliary one is very complex and the mechanism has a great influence on the performances of an engine. Combustion processes in the chamber have been investigated by taking pressure, temperature, ion current and schlieren photographs of the flame. It is found that the duration of combustion, histories of pressure and temperature distribution are greatly influenced by the configuration of the two chambers. But the effect of stoichiometry of the mixture is not so great because the mechanism of combustion is strongly affected by the speed and intensity of the jet.
