Problems solved by technology

Too tight will cause large resistance, consume kinetic energy and cause serious wear; too loose will cause pressure leakage, which is not conducive to pressure to push the piston to move
The same problem exists for lubricating oil. The viscosity is small and the resistance is small, which is beneficial to energy saving, but the sealing effect is poor, and the pressure leakage is not conducive to work; Conducive to energy saving

Abstract

The invention discloses carbon nitride solid particles and diesel engine oil composition containing the same, and belongs to the field of engine lubricating oil production. The solid particles are prepared from C3N3Cl3 and C3N3(NH2)3 under the environment of nitrogen gas and high temperature, and have the characteristics of many lamellas, low sliding resistance between lamellas, small particles, capability of suspending in oil and the like. The engine oil composition is formed by mixing lubricating oil basic oil, high-dispersibility carbon nitride emulsion, a viscosity index improver, a dispersant, a cleaning agent, an anti-oxidant and anti-corrosive agent, a base number storage agent and a defoaming agent. When the engine oil composition is applied to a diesel engine, engine cylinder pressure can be obviously improved; and the engine oil composition is environmentally-friendly and energy-saving and has great popularization and application value.

Description

technical field [0001] The invention relates to the field of engine lubricating oil production, in particular to a carbon nitride solid particle and a diesel engine oil composition containing the carbon nitride solid particle. Background technique [0002] With the continuous increase of diesel engine power, the pressure that the piston needs to bear is also increasing. At present, the seal between the piston and the cylinder liner relies on the mechanical seal and the lubricating oil seal. The mechanical seal is adjusted by the depth and width of the piston ring, cylinder liner and ring groove. If it is too tight, the resistance will be large, the kinetic energy will be consumed, and the wear will be serious; if it is too loose, it will cause pressure leakage, which is not conducive to the movement of the piston by the pressure. The same problem exists for lubricating oil. The viscosity is small and the resistance is small, which is conducive to energy saving, but the seal...
