Abstract

The invention discloses medium-high speed trunk-piston diesel and engine oil, which is prepared from the following components in parts by weight: 80-90 parts of 500SN base oil, 50 parts of 150BS base oil, 1-2.5 parts of polyisobutyl butylene diimide T155A, 1.0-2.0 parts of an over-based sulfurized calcium alkyl phenolate clearing agent T115B, 0.4-0.6 part of nitrogen-containing borate, 2-4 parts of long-chain linear alkylbenzene ultra-high alkali synthesis calcium sulfonate T106D, 1-2 parts of a high-molecular weight polyisobutyl butylene diimide dispersing agent T161A, 1-5 parts of a disimberyl sulfide zinc salt oxidation and corrosion inhibitor T203, 0.2-0.5 part of a phenolic ester antioxidant, 0.1-0.3 part of a dinonyl diphenylamine antioxidant, 0.1-0.3 part of a polymethacrylate pour point depressant T602 and 0.2-0.5 part of a friction modifier oxymolybdenum dialkydithiophosphate T462. Compared with the prior art, the medium-high speed trunk-piston diesel and engine oil has excellent cleaning dispersibility, heat resistance and antioxidative stability, excellent anti-rust and anti-corrosion properties, acid neutralization capacity and alkali value retentivity.

Description

technical field [0001] The invention relates to lubricating oil, in particular to a medium-high speed cylindrical piston diesel engine oil. Background technique [0002] Diesel engines have high thermal efficiency, good economy, easy starting, and great adaptability to various ships. They were used as propulsion power for ships soon after they came out. By the 1950s, diesel engines had almost completely replaced steam engines in newly built ships. Marine diesel engines have been the main power for civilian ships, small and medium-sized ships and conventional submarines. Marine diesel engines can be divided into main engine and auxiliary engine according to their role in the ship. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump, etc. [0003] Most low-speed diesel engines are two-stroke engines, most medium-speed diesel engines are four-stroke engines, and high-speed diesel e...
