Ravinder Pal

Abstract


The present work is to see the effect of atmospheric temperature on performance parameters like mileage, brake specific fuel consumption and thermal efficiency of a vehicle. Experiments were conducted on a car and parameters like mileage, thermal efficiency and specific fuel consumption were computed at various values of atmospheric temperature and speed throughout the year.  The maximum mileage and thermal efficiency of the car was in the month of March.   The minimum specific fuel consumption was for the month of March as compared to other months of the year.  The maximum mileage and thermal efficiency obtained were 22.6 km/litre and 29.48% respectively at speed 1550 rpm, torque 38 Nm and average atmospheric temperature of 290 K.  The minimum specific fuel consumption obtained was 0.275 kg/kWh at 1550 rpm speed, 38 Nm torque and average atmospheric temperature of 290 K. The performance of the car was best in the month of March.
