We encounter a lot of misunderstandings about the use of automotive lubricants in daily car maintenance. The most concentrated are the following: Lubricants can be added more The amount of lubricant should be controlled between the upper and lower tick marks of the oil dipstick. Because too much lubricating oil will enter the combustion chamber from the gap between the cylinder and the piston and burn to form carbon deposits. These coke deposits will increase the engine compression ratio and increase the tendency to produce knocking. Coking in a red hot state in the cylinder will also cause premature combustion. If it falls into the cylinder, it will increase the wear of cylinders and pistons, and it will also accelerate the pollution of the lubricant. Secondly, too much lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases the fuel consumption. When oil becomes dark, it is time to change oil This understanding is not comprehensive. For lubricating oils that do not add a clear dispersant, the color blackening is indeed a sign that the oil has been seriously deteriorated, but the lubricants used in Hyundai Motors are generally added with a decomposing agent. This clearing agent cleans the film and black coke adhering to the piston and disperses it in the oil to reduce the formation of high-temperature deposits in the engine. Therefore, after a certain period of time, the color of the lubricant can easily turn black, but at this time The oil has not completely deteriorated. Lubricants often add no change Regular inspection of lubricants is correct, but supplementation without replacement can only compensate for the lack of oil, but it cannot fully compensate for the loss of lubricant performance. During the use of lubricating oil, the quality of the lubricating oil will gradually decrease due to pollution, oxidation, etc. At the same time, there will be some consumption and the quantity will be reduced. Large use of additives A truly high-quality lubricant is a finished product with a variety of engine protection features. Formulations already contain a variety of additives, including anti-wear agents, and lubricants are the most balanced formulas to ensure full performance of all kinds of performance. Adding other additives by themselves not only does not bring extra protection to the vehicle, but reacts easily with the chemical substances in the engine oil. Lubricating oil six functions When the engine of a car is in motion, violent friction occurs on the surface of the moving parts. The role of automotive lubricants is to form a good oil film between moving parts. Lubricants have six major functions: lubrication, wear reduction, cooling and cooling, cleaning and cleaning, leak-proof seals, rust-proof corrosion, and shock absorption. Owners must give full play to the role of lubricating oil, ensure reliable lubrication of the engine, reduce wear, reduce failures, and prolong the service life of vehicles. Attention must be paid to the selection and use of engine lubricating oil. As long as you can pay attention to summing up your experience and comparing it with yourselves, scientifically selecting lubricants and mastering the oil change cycle, your car will remain youthful and timeless. Concrete Pump Rubber Hose include the wire steel hose and fabric hose ! wire hose usually has 2/4 layers of wire steel, material is natual rubber ,burst pressure is 130bar-200bar, we have sizes DN50-DN150. Fabric hose is usually with the fabric in it, the working pressure is less than the wire steel hose, usually the little sizes are the fabric one, like 2 inch, 3inch. the lengths are so many 1 meter-24meter all we can supply ! My rubber hose inner wall rubber is the integral , will not happened the Inhomogeneous situation, the performance is good , quality is realiable .
