For spark plugs with normal gasoline operation, the surface of the ceramic core should be white, but due to the difference in fuel and additives, the surface of the porcelain core is slightly yellow, reddish or reddish-brown. If the gasoline engine malfunctions, the surface color of the porcelain core will become pale, slightly black and brownish black. From these different colors, different faults of the gasoline engine can be judged.
First, the white porcelain core is miserable. The white porcelain core is white. The center is prone to be fused or chipped. The tip of the side pole is thin and the surface is rough. The surface of the shell protruding into the cylinder has metal peeling and the like, which indicates that the spark plug is overheated. In a multi-cylinder gasoline engine, it only appears on individual spark plugs. It may be because the spark plug's thermal value (heat type) is too low, misuse, poor quality, etc.; if the porcelain core is often white in a certain cylinder, the compression ratio of the cylinder should be checked. Whether deviation, or check the spark plug around the water jacket is blocked. For high compression ratios, attention should be paid to the phenomenon of incandescent ignition; if several signs appear pale at the same time, the load of the steam-sleeving machine should be taken into account, and the capacity of the cooling system should be insufficient. The heat value should be higher. Spark plugs.
Second, the porcelain core was slightly blackish and covered with a thin layer of charcoal. The shell torus and even the side electrodes had carbon deposition. If this phenomenon occurs after a long period of cold car and low speed operation, it will be eliminated after a period of normal use. If it is high under normal conditions, use a low calorific value spark plug. After replacement, attention should be paid to whether the spark plug is overheated, the center pole is melted, and the cylinder is pulled when the gasoline engine is at high speed and high load.
Third, the porcelain core was brown-black spark plug color brown, with a thick block of coke deposition on the shell and side poles, which is the performance of the gasoline engine burning oil, oil from the piston ring or intake valve duct into. Sometimes it is not the cause of the burning oil but the spark plug itself. It is obvious that the porcelain body is broken or the side electrodes are broken. There are also obvious reasons.
Inspection method Place the spark plug on the cylinder head, use the central high pressure to find the spark plug joint bolt about 5 mm, and then toggle the breaker contacts to see the flashover of the spark plug gap. If the spark is intense and blue-white, it indicates that the spark plug is normal. If the spark is weak or there is no spark, the spark plug itself is faulty and should be replaced.

Hydrogen molecular bio-meter using water electrolysis to generate rich hydrogen, because the molecular weight of hydrogen is very small, strong permeability, diffusion speed is extremely fast, the skin is very easy to absorb. The skin is the body`s largest organ, the ability to absorb hydrogen is very large, the absorption of hydrogen can be transported through the skin`s blood to the body to play the role of Health Care.
