Abstract

The invention relates to a formula and a production process for special lubricating oil for a turbosupercharged engine. The formula is characterized in that the lubricating oil comprises base oil and additives, wherein the base oil employs imported synthesized base oil PAO6 and PAO8 and polyol ester TMTC synthesized base oil, the additives comprise a complexing agent P6040, a viscosity index improver SV261 and a pour-point depressant 1-248, and the base oil and the additives are mixed according to a certain ratio. According to the invention, high performance dynamic cleaning and dispersion technology is used, the interior of the engine can be cleaned, aggregation of carbon microspheres can be avoided, accumulation of greasy filth and generation of carbon deposit can be prevented, the engine is cleaner, and the problem of carbon deposit of turbine engines can be effectively overcome; the lubricating oil has long-term antioxidation capability and high temperature resistance, can effectively control increase of viscosity of an oil product, protects the engine from wearing, reduces noise produced by the engine, protects the engine running at high load under the driving conditions of frequent starting and braking, increases pressure for turbines and improves protection of multi-air valve engines.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special lubricating oil formula for a turbocharged engine and a production process thereof. Background technique [0002] The engine generates power by burning fuel in the cylinder. Since the amount of fuel entering the combustion chamber is limited by the amount of air sucked into the cylinder, the power generated by the engine will also be limited. If the engine is running at its best state, increasing the output power can only increase the amount of fuel by compressing more air into the cylinder, thereby improving the combustion performance. Therefore, under the current technical conditions, the supercharger is the only one that can keep the engine's working efficiency unchanged. Common superchargers include mechanical supercharging (supercharge), exhaust gas turbocharging (turbo charge, referred to as turbo), compound twin supercharging and the most recent twin turbocharging....
