Rejestracja optyczna wyładowania iskrowego przy różnych parametrach przepływowych medium gazowego pomiędzy elektrodami świecy zapłonowej

The paper presents the test stand dedicated to optical recording of spark discharge at different flow conditions of gaseous medium between spark plugs electrodes. It also presents the exemplary results of electric arc optical recording. The analyzed flow parameters and pressure correspond with conditions in combustion chamber of spark ignited engine at the moment of ignition. The carried out research allowed better understanding of the influence of flow parameters and pressure of gas on the course of spark discharge and subsequent flame development.
