Lubricating oil composition for inhibiting knocking phenomenon and application thereof

Abstract

The invention discloses a lubricating oil composition for inhibiting a knocking phenomenon. The lubricating oil composition comprises the following components in percentage by mass: 80%-81% of base oil, 0.01%-0.05% of an anti-foaming agent, 8%-10% of a viscosity index improver, 4.5%-5.5% of a purification dispersant, 2.5%-3.5% of an anti-wear agent and 1%-2% of an oxidation and corrosion inhibitor. By optimizing the formula of the lubricating oil composition, the mass of lubricating oil entering a combustion chamber is reduced, and compounds capable of causing spontaneous combustion are reduced, so that the detonation phenomenon is inhibited.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil composition for suppressing detonation and its application. Background technique [0002] Lubrication can improve the friction state and reduce friction resistance, which is an effective anti-friction measure. Lubrication at the contact position between the engine piston and the cylinder can effectively improve the working conditions of the piston. The function of lubricating oil is to form a layer of oil film on the working surface of the two to reduce frictional resistance and make the work smoother. Although lubricating oil has many advantages, domestic and foreign studies have found that lubricating oil can cause low-speed pre-ignition, thereby causing knocking. Lubricating oil can enter the combustion chamber in various ways. During the movement of the piston, the lubricating oil accumulated in the piston ring land gap is thrown into the combusti...
