Development and Evaluation of Air Compressor on Agricultural Tractor

The experiment was conducted in Darmali village, River Nile State, Sudan, to design an air compressor, which will be installed in the rear of tractor and operated from the tractor PTO shaft. An air container was added for air saving under pressure. The installation included three iron frames A, B and C in addition to flexible hoses and air pressure gauges. The compressor tests were carried out for three types of tires: 10//, 16// and 38// (three times a day, 10 am, 12 midday and 3 pm). It was compared with two air filling mechanisms, manual and in a workshop. Obtained results showed that the difference on fuel consumption between loaded and unloaded compressor was 103.2 ml/hr. Also the results indicated that the compressor had no significant effect on fuel consumption during operation although it was significantly affected the time taken for tires air filling. The time taken for air filling for the tires 10//, 16// and 38// was (0.73 hr, 4 hr and 0.01 hr), (2 hr, 4 hr and 0.05 hr) and (7.3 hr, 4 hr and 0.12 hr) with manually, in workshop and by designed compressor, respectively.
