In this study, the effect of gas fuel composition whose components are CH_4, N_2 and CO_2 on combustion was experimentally investigated to propose a small gas engine system for appropriate combustion with biomass gas fuel. As a result, longer combustion duration and cyclic variation of pressure profile with increasing dilution rate were observed. This trend was more apparent in CO_2 dilution than N_2. Therefore, we can conclude that not only dilution rate but also kind of chemical species influenced engine combustion. Subsequently, effect of spark timing on combustion was investigated. As increasing dilution rate, to advance spark timing is necessary to keep high thermal efficiency and low cyclic variation in gas engine operation.
