Limited fossil fuel supplies and the necessary reduction in toxic fumes emission to the atmosphere are themain motives in conducting a search for the new, effective energy supplies. The one with potential is biogas. It is theproduct of natural fermentation processes of municipal waste in landfills or is produced in biogas plants out of agriculturaland green waste. Due to creation under different conditions, its chemical composition varies. This is enormousobstacle in its effective application. Biogas is easily applied to fuel spark-ignition engines however intensive attemptsare made to employ it in much more effective compression-ignition engines. Application of biogas require the use ofdual-fuel CI engine. The point of the research described in this paper is to show the influence of different methanecarbondioxide composition ratio in biogas on dual-fuel CI engine effectiveness.
