Performance and emissions characteristics of n-pentanol mixed with premium motor spirit and camphor blend in spark ignition engine

Abstract

In this work, pentanol and camphor blended with petrol in different proportions were used on spark-ignition engines to evaluate their performance, characteristics, and emissions. Sample P0A (gasoline) showed the best specific fuel consumption for the lower torque (3Nm) with a value of 19.2Kg/kWh, and sample P0B (100% of pure gasoline and 5% camphor) had the best fuel consumption for the higher torque (6Nm) with a value of 12.9Kg/Kwh. For brake thermal efficiency, sample P0B gives the best brake thermal efficiency at the two-constant torque with a value of 0.34 for torque 3Nm and 0.65 for torque 6Nm respectively. Sample P15A (85% of gasoline and 15% of pentanol) gives the best BMEP at torque 3Nm with a value of 1.97bar and sample P5C (95% of gasoline and15% of pentanol) gives the best BMEP at 6Nm with a value of 3.87 bar.
