Problems solved by technology

Since the lubrication method of the two-stroke outboard engine is mixed lubrication, the lubricating oil directly participates in the combustion and produces a large amount of exhaust gas, causing serious pollution to the water environment
Moreover, with the high load, high speed, humid working environment and catalytic device application of outboard motors, higher requirements are put forward for outboard motors, and it is difficult for two-stroke outboard motors to meet the development needs of outboard motors.

Abstract

The invention provides a four-stroke outboard engine oil composition capable of satisfying NMMA FC-W specification, which comprises the following components by weight percentage: 0.5-1.3% of antirust agent, 0.02-0.10% of friction improver, 2.0-4.5% of purification dispersant, 0.2-0.8% of anti-oxidant, 1.0-2.0% of oxidation and corrosion inhibitor, 6.0-15.0% of viscosity index improver, 0.1-0.3% of pour-point depressant, 0.001-0.005% of antifoaming agent and the balance of synthetic base oil. The four-stroke outboard engine oil composition has excellent lubricity, cleanliness and anti-rust property, can satisfy the requirements of smog corrosion test prescribed by NMMA FC-W and 115HP GPET stand test, and can reach the requirement of the national marine manufacturers association NMMA FC-W specification.

Description

technical field [0001] The invention relates to engine oil lubricating oil, in particular to a four-stroke outboard engine oil lubricating oil. Background technique [0002] At present, domestic and foreign outboard engines are still dominated by two-stroke outboard engines, and this type of equipment uses two-stroke outboard engine oil for engine lubrication. Since the lubrication method of the two-stroke outboard engine is mixed lubrication, the lubricating oil directly participates in the combustion, which produces a large amount of exhaust gas and causes serious pollution to the water environment. Moreover, with the high load, high speed, humid working environment and catalytic device application of outboard motors, higher requirements have been put forward for outboard motors, and it has been difficult for two-stroke outboard motors to meet the needs of outboard motor development. [0003] In order to adapt to the development of the outboard motor industry, more and mo...
