A computer based data acquisition and control system was used for controlling all variables like revolution per minute RPM and relative air fuel ratio AFR. Exhaust emissions of both of the fuels were analyzed and compared using the DesignExpert 8.0. The analysis of exhaust gases was done by means ofone of the top notch crypton gasanalyzer. Resultswere recorded under steady state operating conditionsby controllingthe revolution per minute (RPM)and relative air fuel ratio (AFR) of the engine. Equipment was assembled to carry out different exhaust emission testsfor simple spark ignition (SI) enginemodified to run on Bi-fuel (Compressed natural gas/ Gasoline) for the required data.
