Abstract: The demand for transport fuel has been increasing and expectations are that this trend will remain unchanged for the coming decades. Variations in the emissions the of carbon dioxide (CO₂) carbon monoxide (CO) and hydrocarbons (HCs) have been computed for various blends of soyabean and mustard oils with petrol at different engine loads in computerised variable compression ratio multi-fuel (CVCRM) engine test rig. It is concluded that out of the two mustard oil blends, 20-PRM shows the lowest carbon monoxide (CO) emissions (in percentage) at all the engine loads i.e., 2.5 kg, 5 kg and 7.5 kg, where as the blend of 20-PRM shows almost zero carbon monoxide (CO) emissions at the load of 7.5 kg. The emission of carbon dioxide (CO₂) decreases on increasing the engine load for the blend of 15-PRS while it increases on increasing the engine load for other fuels.

Keywords: carbon dioxide; CO2; carbon emissions; carbon monoxide; hydrocarbons; biofuels; CVCRM engine test rig; engine loads; fuel performance; blended fuels; soyabeans; mustard oils; variable compression ratio; engine performance; vehicle performance.
