The invention discloses a miller cycle engine lubricant composition, using HVIH 6 base oil as the base oil, compounding various additives, including: detergent, dispersant, anti-oxidation and anticorrosion agent, antioxidant, anti-rust agent, metal reducer Activator, friction modifier, antifoam agent, auxiliary agent, pour point depressant. The lubricant composition of the present invention has good high-temperature oxidation stability, rust resistance, low-temperature fluidity, acid neutralization ability, shear resistance, and can inhibit the formation of low-temperature sludge, paint film and carbon deposition, low ash content, Features that reduce emissions of nitrogen oxides, soot, carbon monoxide, and hydrocarbons.
Description
technical field [0001] The invention belongs to the field of engine lubricants, in particular to lubricant compositions for Miller cycle engines. Background technique [0002] How to use the energy generated by fuel more effectively is a key technology to improve engine efficiency. Since the birth of the internal combustion engine, the compression ratio is generally considered to be a constant value, but from the Atkinson cycle in the 19th century to the Miller cycle operation mechanism in the 20th century, it has broken through the shackles of constant compression ratio. If you want to improve engine power, increasing the compression ratio is a technical means; if you want to improve the fuel economy of the engine, you can also start with increasing the compression ratio. However, the actual compression ratio cannot be increased without limit. Therefore, in order to take into account low fuel consumption, high output and excellent drivability, the Miller engine uses an in...
