M. and Vijayakumar, S. N. and Aros, R. B. T.}, abstract = {This study synthesizes biogas with low methane contents ({\ensuremath{<}}50) to hydrocarbons that form a combustible synthesis gas (syngas) mixture. Conventional methods used for reforming biogas has limitations in terms of fabrication, maintenance, and cost. This is especially true when the biogas' composition fluctuates. Non-thermal plasma (NTP) is an alternative method to produce combustible syngas for power generation. Thus, the exhaust emissions from a 2 kWe spark ignition (SI) engine fuelled with gasoline and NTP-synthesized biogas is investigated with respect to the type of NTP reactor, plasma power consumption and biogas composition. Two types of NTP reactors are used: a cylindrical reactor where the gas flow path is linear, and a cyclonic reactor where the gas flow path is a curvature, similar to that of a gas-solid cyclone separator. The results show that the NTP reactors produced additional hydrocarbons, decreasing flue gas temperatures by 4 C and reducing NOx emissions by 35. {\^A}{\copyright} Published under licence by IOP Publishing Ltd.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85122481497&doi=10.1088\%2f1755-1315\%2f945\%2f1\%2f012025&partnerID=40&md5=24906083502d9c1bd0d5266100ffa56a} }
