4 Add new type of ceramic particulate lubricant to the engine lubricating oil, so that the engine in the course of the work, the formation of ceramic membrane in the engine parts of the surface, in order to prevent all parts of the åž face contact, from the line to reduce the Division Secretary Friction noise 3 Dong reduce the noise generated by friction between the tire and the road The advantage of porous fat blue is that it has many pores, strong elasticity, can absorb a large amount of energy, and can convert large vibration energy into internal heat energy, which attenuates the vibration noise when the vehicle is driving. Road building can make the road surface form a convex surface with particles to reduce the vibration of the vehicle body, thereby reducing noise. , Identification of gasoline and kerosene Oxygenated gasoline is more volatile than kerosene. When fingers or wooden sticks are stained with oil, the gas that volatilizes rapidly is gasoline, and the volatile gas is kerosene. In addition, there is a cool feeling when the gas is on the hands, and it quickly evaporates. The kerosene on the hands is not easy to dry. Burning gasoline is easier to burn than kerosene. Gasoline and kerosene are each taken in containers and fire bows are used; burning, petrol is immediately on fire, kerosene is easy to catch fire. Smell the smell with the smell of the nose, stimulating the sense of knowledge swirl swirling two bottles of oil, the swirl disappears slowly for gasoline, swirl quickly disappeared is kerosene. After seeing the bubbles shaking the two bottles of oil, the foam disappeared faster than gasoline. The slower foam disappeared was kerosene, and the fuel oil and gear oil were discriminated against a small amount of test oil smeared on thick paper. Huang Jun observed and compared. On the back of the penetrating oil trace is fuel oil; no penetrating oil traces, and on the paper surface still has good lubricity for the gear oil. You can also apply the same amount of two kinds of oil on thin paper, try to look at the temperature of the fire, ignite with a match, burning faster is the fuel oil, burning, the slower is the gear oil. The Kerosene and Diesel Identification Technology view color kerosene, the color is lighter, is colorless or yellowish. The color of diesel is darker, light yellow or dark yellow. When you see a lamp lit with smoke, don't take it. Smoke is kerosene, smoke is diesel. The mass of oil of the same mass is measured, and the mass is diesel, and the mass is kerosene. When the vortex is shaken in the bottle, the kerosene is fast, the light diesel oil and the fuel oil recognize the odor, the fuel oil has a strong burnt odor, the heavy diesel oil takes the second place, the light diesel oil has no coke odor, and the viscosity of the viscous oil is different. The viscosity of light diesel oil is the smallest, the viscosity of heavy diesel oil is large, and the viscosity of fuel oil is the largest. The color light diesel oil is light yellow to dark yellow, the heavy diesel oil is dark brown to green, the fuel oil is brown green to black, and the editor of the mouth column is Guan Lizhe Mehd Electric Telescopic Mast,Extendable Antenna Pole,Push Up Antenna Mast,Telescopic Aerial Pole TIANHEMAST , https://www.robomasts.com
