Optimised operation of engines running on gasification gas

Experimental investigations were conducted on two identical small-scale SI gas engine generator sets operating on biomass-produced gas from thermal wood gasification. The engines operated with two different compression ratios, one with the original compression ratio for natural gas operation 9.5:1, and the other with a compression ratio of 18.5:1 (converted diesel engine). The project proved that the engine could operate at high compression ratio SI when operating on this specific biomass-produced gas. The results showed an increase in electrical efficiency from 30% to 34% at increased compression ratio. (Energi 10)
