Description

technical field

[0001] The present invention relates to a modified liquid, more specifically, the present invention relates to a filter paper modified liquid, and at the same time, the present invention also relates to a preparation method and application of the filter paper modified liquid. technical background

[0002] Filters (including air filters, diesel filters, and oil filters) are important parts of the engine. Both are referred to as particles) to reduce the wear of engine cylinder liner piston rings, crankshaft connecting rod kinematic pair and high-pressure oil pump plunger couple, optimize the combustion process of the engine, and reduce the emission of carbon monoxide, nitrogen oxides, hydrocarbons and other pollutants . With the implementation of engine emission regulations (Euro II, Euro III), the engine puts forward higher supporting requirements for the filter efficiency and other indicators of the filter.

[0003] Generally, the filter-type trapping princ...
