| Abstract: | An opto electronic measuring system is developed for the monitoring and analysis of the combustion process in an engine. It consists of a fiber optic combustion sensor with a filmed sapphire probe, a measuring circuit with PMT as the photodetector pickoff and the data acquisition and analysis softwares. The system has been used in a petrol engine for practical measurement. The results obtained show that the time parameters of the combustion process can be accurately measured with the optic method. From the characteristics of light intensity variation, the relationship between the uniformity of gas mixture and the cycle to cycle fluctuation during combustion can be obtained. |
