Abstract: A new method was proposed to improve lean burn combustion performance of natural gas engine and to solve the problems of high ignition energy and slow flame speed of combustion of natural gas in lean burn condition by using the ozone with strong oxidation. The influence of ozone addition on laminar flame speed was studied and numerical analysis of chemical mechanism was carried out using Chemkin software. Results showed that laminar flame speed increased with ozone addition and improvement was more obvious with lean mixture. Moreover, laminar flame speed could be increased in different temperature and pressure situation with ozone addition and the maximum increment of laminar flame speed could reach 36%.The concentration of free radicals and intermediate products increased obviously with ozone addition and then improved the combustion characteristics of methane.

Key words: natural gas, laminar flame speed, ozone, Chemkin, chemical reaction kinetics
