ABSTRACT -The paper presents a study of the environmental performance of a gasoline engine running on upgraded biogas. The parameters obtained are compared with those of the test running of the same engine on gasoline. The investigation of the operation on upgraded biogas involves conducting of multiple tests, providing corrective characteristics corresponding to various air-fuel ratios and ignition timing.
Keywords: air-fuel ratio, bio fuels, ecology, ignition timing, upgraded biogas
