Study Wear of the Agricultural Engine by Using Yang-Na Oil

摘要

Yang-Na is ranked 9th in the Plant Genetic Conservation Project Under the Royal Initiation of Her Royal Highness Princess Maha Chakri Sirindhorn (RSPG) in Her Royal Highness Princess Maha Chakri Sirindhorn. This research was aimed at evaluating the durability of two four-stroke one-piston agricultural diesel engines by comparison between the engine using refined yang-na oil mixed with diesel (B40) and the engine using diesel in terms of engine components. The agricultural engines were tested by measuring their performance in pumping water continuously for 300 hours at 1,400 rpm. Monitoring wear in this research was performed measurements of 14 pieces in combustion chamber. The results show the agricultural engine using B40, the wear compositions are not much happening, such as cylinder, piston, piston-ring 1 and 2, intake-exhaust valves etc. The wear that occurs in the test was found not wear more than the standard engine for the wear. Only the piston rings, engine oil B40 that is worn close to the standard as possible.
