Assessment of the Environmental Impact of Using Methane Fuels to Supply Internal Combustion Engines

This research paper studied the environmental impact of using methane fuels for supplying internal combustion engines. Methane fuel types and methods their use in engines were systematized. The knowledge regarding was analyzed. authors properties various used different applications (specialized power generators—Liebherr G9512 MAN E3262 LE212, powered by biogas, engine road off-road vehicles—Cummins 6C8.3, self-ignition, original version diesel fuel, its modified version—a spark-ignition fuel) under operating conditions approval tests. sensitivity properties, especially pollutant emissions, to states studied. In case a Cummins 6C8.3 engine, significant reduction emission owing relative self-ignition found. carbon oxide decreased approximately 30%, hydrocarbons 70% nitrogen 50%, as well particulate matter also eliminated. Specific brake is most sensitive engine: 0.324 0.264 with least being specific oxide: 0.121 0.097 engine. monoxide stationary higher comparison both versions However, lower than
