Abstract

The invention relates to a free-piston linear generator lubricating oil additive and a preparation method thereof. Additives include metal detergents, ashless dispersants and phenolic ashless antioxidants. The preparation method is to weigh the metal detergent, the ashless dispersant and the phenolic ashless antioxidant in proportion, then mix them at a temperature of 70°C-90°C, and fully stir them for 2-3 hours until they are evenly stirred. The lubricating oil prepared by using this additive can meet the lubricating requirements of the free-piston linear generator under harsh conditions, and has the characteristics of low ash content, excellent piston cleaning performance and good lubricating performance.

Description

technical field

[0001] The invention belongs to the technical field of lubricating materials, in particular to a lubricating oil additive for free-piston linear generators. Background technique

[0002] The free-piston linear generator is an innovative and highly operable future power device, and it is one of the research directions of hybrid power for new energy vehicles. As a new type of series hybrid power device, it has received extensive attention from many research institutions and companies at home and abroad in the past ten years. The device is directly coupled with a free-piston internal combustion engine and a linear generator. The combustion chamber expands to do work, and the gas spring recovers after storing energy, thereby driving the linear generator to reciprocate to generate electricity.

[0003] Toyota has transformed the device from theory to reality and developed a free piston linear generator (FPEG). FPEG generates electricity through a power generatio...
