ABSTRACT
In this study, biogas was produced by anaerobic degradation of kitchen waste, and then it was subsequently injected in a dual fuel compression ignition (CI) engine. In experimentation, kitchen waste biogas (KWB) introduced into the engine intake manifold using fumigation technique at ambient condition. Various engine characteristics such as performance and emission were evaluated at various brake mean effective pressure (BMEP). The NOx and SOx formation of 49 and 30 ppm, respectively, were observed, which is less in comparison to single mode NOx (157 ppm) and SOx (34 ppm). Thus, usage of KWB under dual mode in CI engine improves the performance of the engine, as well as reduces harmful emissions.
