Abstract
The paper presents an experimental study of the processes of ignition and combustion for a stoichiometrical propane-oxygen mixture in a closed volume (a single cylinder of internal combustion engine). The object of study was the dynamics of gas ignition and combustion in a cylinder of diameter D = 72 mm and height h = 4 mm as a function of location of N spark points for ignition ( N = 1÷9) under the condition of simultaneous ignitions. The big number of ignition points reduces the interval for generating the force impact on the engine’s piston and increases the maximum amplitude of the force.
