Research on quality evaluation of lubricating oil based on China’s independent development

Abstract

At present, China has become the largest automobile production and sales country in the world, and the second largest lubricant consumption country. It is of great significance to establish China’s independent certification and evaluation system for lubricants.In recent years, China’s heavy-duty diesel engine has basically realized the technology autonomy, and the mode of lubricant evaluation standard equivalent to API specification is not suitable for China’s national conditions. It is imperative to develop a diesel engine oil quality evaluation research that is suitable for China’s national conditions. This paper mainly introduces a series of research on the performance difference of JAC 2.0TCI engine based on the physicochemical, wear and sediment evaluation of different reference oils under the condition of fuel dilution.
