  Abstract:  The development of a new optical method to measure the delay time following the spark ignition in gaseous explosive mixtures, based on the measurement of the emitted radiation intensity detected with a photo diode active in visible and near infrared range is presented. Several CH4-air-inert mixtures were used to test the validity of the method. Our results are comparable with the available literature data. The influence of the different operational factors was investigated to establish the range of the optimum conditions.

Keywords: spark ignition, ignition delay, emitted radiation intensity, CH4-air-inert mixtures
