Abstract

The invention discloses a lubricant composition for operating an engine, which adopts oil-soluble polyether PAG as base oil, and is mixed with various additives, including: detergent, dispersant, anti-oxidation and anticorrosion agent, antioxidant, anti-rust agent, extreme pressure agent, antiwear agent, metal deactivator, antifoaming agent. The composition of the present invention has high load-bearing capacity, good cooling performance, sealing performance, lubricity, anti-emulsification performance, anti-rust performance, anti-corrosion performance, stable shear resistance performance and friction performance, good mechanical performance and storage performance, and oxidation stability. It has good compatibility with sealing materials and is suitable for working for a long time under high speed, high temperature, vibration, variable load and impact load.

Description

technical field [0001] The invention belongs to the field of engine lubricants, in particular to a lubricant composition for operating engines. Background technique [0002] The steering engine is a piston-type external-combustion engine with a special structure. It replaces the traditional crank-link mechanism with an oblique shaft mechanism, and the cylinders are evenly arranged in the circumferential direction. The thermal process in the cylinder is basically the same as that of the traditional engine. The fuel is burned in the combustion chamber to produce high-temperature and high-pressure gas working fluid, which is distributed to each cylinder by the rotating gas distribution mechanism to convert thermal energy, push the piston to reciprocate, and pass the reciprocating movement through the space linkage mechanism. Converted to rotational motion of the spindle. Finally, the inclined shaft is driven by the operator to output power. [0003] The main components of the...
