ARTICLE ANNOTATION

quote
Recent studies focus on the impact of extreme climatic conditions on mining transport equipment performance. In hot climates (over +50°C) with high dust levels, motor oils in heavily loaded engines are quickly contaminated with impurities. The Muruntau quarry, a unique mining site with a depth of 620m and road lengths of 65–70 km, presents challenges such as reduced diesel engine power (by 20–25%) and rapid insulation degradation. This study evaluates the quality of SAE15W-40, API CI-4/SL motor oils used in CAT-789D dump trucks under these harsh conditions.
