RESEARCH PROGRESS OF HIGH-GRADE DIESEL ENGINE OIL ADDITIVES AND FORMULATION TECHNOLOGY

Abstract

Abstract: The quality standard of diesel engine oil has been upgraded due to the requirement of environmental protection and energy conservation. The quality of API CH-4 and above high-grade diesel engine oils has been greatly improved in many aspects. The progress of high grade diesel engine oil additives and formulation technology in recent years was reviewed. The technical improvement routes and its development trend to meet the specific performance of oil soot dispersion, wear resistance, anti-oxidative performance and exhaust after-treatment compatibility of diesel engine oil were investigated. The analysis results showed that the development of additives and formulation technology for high-grade diesel engine oil was mainly embodied in the development of new structural additives, the optimization of compatibility and synergy among additives, and the optimization of formulation for thickened base oil of lubricating oil. On this basis, some guiding suggestions were put forward for the research and development of domestic high-grade diesel engine oil products.

Key words: diesel engine oil, additive, formulation
