Abstract

The invention discloses a castor-oil-based ethanol fuel engine oil composition. Dioctyl sebacate and pentaerythritol ester, which are prepared from castor oil, are compounded into base oil, and a plurality of composite additives comprising a detergent, an antioxidant preservative, a dispersing agent, an antioxidant, an oiliness agent, an antirust agent, an antifoaming agent and a reinforcing agent are matched. According to the castor-oil-based ethanol fuel engine oil composition, a dense protective film is formed on the surface of a kinematic pair of an engine, so that the friction and abrasion of the kinematic pair of the engine can be effectively reduced, and the erosion of an ethanol fuel can be resisted; the composition has high low-temperature flowability, high-temperature oxidation resistance, acid neutralizing capability, detergency and dispersity, and the formation of oil sludge and carbon deposit is reduced; the composition has low volatility and emission performance and high antirust and anticorrosive performance, the power of the engine can be maintained, and the lubricating requirements of an ethanol fuel engine system can be met.

Description

technical field [0001] The invention belongs to the field of internal combustion engine lubricants, especially castor-based ethanol fuel engine oil compositions. Background technique [0002] Since the 21st century, the diversification of energy and vehicle fuels, the development and application of renewable energy such as material energy and clean alternative fuels are an inevitable trend to solve the shortage of mineral fuels, purify the air and protect the environment. Ethanol is a common fuel energy substitute product. It is an oxygen-rich fuel with a density similar to that of gasoline. These two fuels can be directly mixed and miscible (gasoline alcohol), directly applied to gasoline engines, without changing the structure of the engine, and can maintain the performance of the original engine. Therefore, the application technology of ethanol fuel on gasoline engine has been quite mature, and gradually develops towards the direction of pure ethanol engine. [0003] Th...
