Effect of compressed natural gas on performance and emission of a 4-stroke spark ignition engine /

This thesis deals with experimental study of a four-stroke spark ignition engine. The objective of this thesis is to evaluate the performance and emission characteristics of the engine while using conventional fuel, gasoline and alternative fuel, compressed natural gas (CNG). The engine operated und...
