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

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