چکیده انگلیسی
Motorcycles were selected to determine their fuel consumption and exhaust emissions following ECE driving cycles. Exhaust constituents including CO2, CO, NOx, total hydrocarbons (THC) and hydrocarbon species (27 paraffins, 9 olefins, 16 aromatics and 15 carbonyls) were investigated for this work. The age of 10- 90% of the selected motorcycles ranged from 2.5 to 12.4 years, and their mileage ranged from 5400 to 39,300Â km. CO emission ranged from 1.4 to 6.4Â g/km (median value: 2.98Â g/km), THC from 0.41 to 1.54Â g/km (median value: 0.98Â g/km), NOx from 0.16 to 0.28Â g/km (median value: 0.21Â g/km), CO2 from 58.9 to 62.2Â g/km (median value: 60.5Â g/km) and fuel consumption from 30.7 to 36.4Â km/L (median value: 33.4Â km/L), corresponding to the percentage cumulative data from 10 to 90% of the selected motorcycles. Results indicated that the motorcycle exhaust emission and fuel consumption depended on their mileage and ages. An increase in mileage of 1000Â km resulted in an increase of 103Â mg for CO emission and 14.7Â mg for hydrocarbon emission and a reduction of 1.52Â mg NOx emission and 0.11Â km per liter fuel consumption. For various VOC groups, a mileage increase of 1000Â km corresponding to the increased exhaust emission of paraffins was 6.71Â mg, olefins 1.90Â mg, aromatics 7.04Â mg, carbonyls 0.283Â mg and 67 VOC species 15.9Â mg. Fuel consumption and emissions of CO and hydrocarbon increased in motorcycles over the guaranteed mileage of 15,000Â km.
