Problems solved by technology

[0004] Replacing special-purpose four-stroke motorcycle oil products with gasoline engine oil of the same quality level cannot meet the low-friction operation requirements of some small-displacement, pedal four-stroke motorcycles, resulting in increased engine start-up wear and severe pitting of transmission gears. The clutch slips and the durability deteriorates, the upper part of the engine cylinder wall, the piston ring bank, and t

Abstract

The invention provides a lubricating oil composition with low frictional characteristic for a four-stroke motorcycle (JASO T903-2011 frictional characteristic is classified as MB or ISO 24254 is classified as EMB). The lubricating oil composition comprises the following components in percentage by weight: 1-12% of a viscosity index improver, 1-4% of a medium-high basic value clearing agent, 0.5-3%of a dispersing agent, 0.1-2.0% of an oxidation and corrosion inhibitor, 0.05-0.4% of an antioxidant, 0.1-1.0% of a friction modifier, 0.0001-0.01% of an antifoaming agent, 0.05-1.4% of a pour pointdepressant and the balance of base oil. The lubricating oil composition disclosed by the invention has low friction coefficient, good shearing performance and viscosity retention capacity and excellent abrasion resistance, and a motorcycle engine can still ensure smooth system operations under high temperature and high speed.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition for a four-stroke motorcycle with low friction characteristics, and belongs to the technical field of lubricating oil additives. Background technique [0002] Since 2006, the Japanese Automobile Standardization Organization JASO T903-2006 has carried out a major upgrade, raising the minimum quality level of lubricating oil for four-stroke motorcycles (hereinafter referred to as: four-stroke motorcycle oil) from SE level to SG, clutch The classification of friction coefficient was revised from MA, MB to MA, MA1, MA2, MB. In 2011, JASO T903-2011 underwent a major revision, and the range of friction coefficient of oils with high and low friction properties was further narrowed. [0003] China is the largest exporter of motorcycles. The implementation of national emission standards and the demand for product upgrading in the world have improved the qualit...
