Abstract

تعد باصات النقل الداخلي مصدراً رئيساً من مصادر التلوث؛ وذلك بسبب حركتها المستمرة في شوارع المدينة. وترتبط نسبة الملوثات المنبعثة من هذه الباصات بسرعتها وبتسارعها وبعدد الركاب الذين تقلهم. وقد بيّنا في هذا البحث أن نسبة أكاسيد النيتروجين NOx وثاني أكسيد الكبريت SO2 الصادرة عن هذه الباصات تزداد بزيادة السرعة والتسارع وتقل مع زيادة الحمولة وأما بالنسبة إلى ثاني أكسيد الكربون CO2 والهيدروكربونات CxHy فقد وجد أن نسبها تزداد بشكل مستمر عند الحمولة العالية مع زيادة السرعات. وقد لوحظ أن أدنى مستوى من الانبعاثات يمكن تحقيقه عندما يتحرك الباص بحدود السرعة 30 km/h والحمولة العالية.

 

Public transport buses are considered as a major pollution source, due to their constant motion in the city-streets. Emission pollutants ratio, released by these buses, vary according to their speed, acceleration and passenger-loads. In this study, I have demonstrated that the ratio of nitrogen oxides NOx and sulfur oxides SO2 emitted by these buses increases in line with speed and acceleration and decreases as a result of increasing loads. As for carbon dioxide CO2 and hydrocarbons CxHy it is revealed that ratios continuously go up with high speeds and heavy loads. Equally evident is the fact that the minimum level of emissions can be attained, when the bus's speed is 30 km/h and its load is high.
