Problems solved by technology

[0009] (3) Intensified corrosion and wear
[0014] (3) The cooling performance of the engine using gaseous fuel is worse than that of diesel and gasoline, which will increase the heat load of the engine, so it is required to use lubricating oil with better oxidation resistance and high-temperature detergency than conventional engine oil;
[0015] (4) Compressed gas itself has no lubricating effect, which may easily cause wear of the intake valve, exhaust valve and valve seat, requiring better anti-wear performance of lubricating oil
This is too short compared to the 20,000 to 30,000 km oil change cycle of diesel engine oil, which will increase the user's oil change cost, maintenance cost, and oil change man-hours, which is also a big waste from the perspective of energy consumption. and waste

Abstract

The invention belongs to the technical field of lubricating oil development, and particularly relates to long-service-life gas engine lubricating oil which consists of the following components in parts by weight: 30-35 parts of 6# base oil, 45-50 parts of 500N base oil, 10.5-12.6 parts of a gas engine oil composite additive, 0.3-0.4 part of an anti-oxidant, 0.55-0.85 part of an anti-wearing agent, 6.6-7 parts of a tackifier, 0.3-0.35 part of a pour point reducer and 10-30*10<6> parts of an anti-foaming agent. The long-service-life gas engine lubricating oil can improve high-temperature stability, oxidization resistance and nitration resistance of oil, so that the oil has higher oxidization resistance, and has better abrasion resistance; moreover, the oil change period of oil can be prolonged by twice or more, and the service life of the oil is prolonged to be 0.04 million kg at most, so that the oil becomes the long-service-life gas engine oil.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil research and development, in particular to a long-life gas engine lubricating oil. Background technique [0002] With the development trend of optimizing the energy structure and reducing emissions, the application of gas engines is becoming more and more extensive. A gas engine is an engine that uses natural gas as fuel, and its carbon monoxide and particulate matter emissions are far lower than those of gasoline engines and diesel engines. It is an ideal low-emission alternative energy source. Applications of natural gas as an alternative fuel for engines include compressed natural gas (CNG), liquefied petroleum gas (LNG) and gas-to-liquids (GTL). At present, CNG is the most widely used in China, and the technology is relatively mature. [0003] Natural gas, as the preferred new energy, has been recognized in the engine industry, and has developed rapidly in recent years, and various e...
