Problems solved by technology

[0003] At present, the price of engine lubricating oil for natural gas on the market is higher than that of ordinary gasoline engine oil. It is difficult to promote the use of natural gas engine lubricating oil to natural gas and gasoline dual-fuel vehicles. The engine lubricating oil used in such vehicles is still gasoline engine lubricating oil , because natural gas and gasoline dual-purpose fuel engines use natural gas, the temperature of the combustion chamber is high, the temperature of the exhaust gas is high, the gasoline engine lubr

Description

technical field [0001] The invention belongs to the technical field of improving specific physical properties or chemical properties with additives characterizing lubricating oil compositions, such as multifunctional additives. Background technique [0002] As people's awareness of energy saving and environmental protection gradually increases, countries have stricter air quality control and vehicle emission requirements. As one of the effective means to solve the problem of vehicle emission pollution, gas vehicles have a very bright development prospect. The world's major automobile manufacturing companies are stepping up the development and research of gas fuel (compressed natural gas or LPG) engines, dual fuel (natural gas and diesel or LPG / diesel) engines and dual fuel (natural gas and gasoline or LPG / gasoline) engines. The natural gas and gasoline dual-purpose fuel engine vehicle is to install a natural gas-type vehicle compressed natural gas supply device under the con...
