Do You Know, Lubrication Is Vital To Protect Porsche Cayenne 2012 For Sale
The function of the lubricant is to protect the moving parts of a porsche cayenne 201 for sale, reducing friction and wear. It also acts as a refrigerator and takes care of cleaning, dragging and debris removal. For motor oil, for example, to be able to successfully carry out this work, they need chemical substances that are additives. These components are added to the base oil (mineral or synthetic) to form, together with the thickeners, the final lubricant with all those properties that enable the lubrication of the equipment to be correct.
If you look at the composition of a lubricant or when you read its technical sheet, you will find the term additive in reference to these agents that enhances its function. Functions of Additives are vital; the additives, therefore, improve the performance parameters of the base oil, enhancing the existing properties; deleting those that are not valid; or introducing new properties that optimize the efficiency of the lubricant or oil. They prevent the oxidation of the oil. They slow down negative effects such as filter wear or blockage. They improve the fluidity of the oil. In a lubricant, the proportion of additives is usually respective of the volume of the formulated oil. These chemical compounds can be organic or inorganic; be dissolved or solid in the oil.
Types Of Additives
To understand the behavior of these components, below, we explain what types of additives are the most frequent and what they are for. Additives that improve the properties of the base oil are discussed below
Antioxidants: functionality of the lubricant is limited by oxidation or aging of the base oil. These additives are responsible for slowing down this oxidation process by preventing the formation of acids, sludge and increases in viscosity derived from oxidation.
Corrosion inhibitors and anti-rust: the condensation of water inside the machinery causes oxidation and corrosion, processes that must be repelled, thanks to a lubricating film that forms on the water-resistant metal parts.
These additives are responsible for protecting the bearings by sealing the surfaces that are in contact with water and corrosive acids.
Defoamers: these additives prevent the formation of bubbles that would bring air into the lubrication circuit and accelerate the oxidation process of the lubricant.
Thinners - These additives allow the lubricant to flow at low temperatures.
New Properties to Base Oil
Antidesgates and Extreme Pressure Additives (EP): these components are essential to avoid welding of moving parts. They adhere to metal surfaces, creating a solid film of lubricant that prevents metal-to-metal contact. Detergents additives work in the most important part of the engine (rings, cylinders, pistons and valves) keeping the surfaces clean of deposits. Mainly, they are cleaning agents and fight the effects of high temperatures, that is, what causes oxidation of the lubricant. Dispersants additives stabilize contaminating residues during the life of the lubricant, such as soot particles from diesel engines or gasoline sludge. They also slow down the negative effects of increased viscosity, wear, or filter blockage. Friction modifiers additives react chemically with metal surfaces to form a thin protective film.
As you can see, thanks to the additives, the engine components are protected against situations that can damage the operation of the engine, preventing premature engine failure. It is important to remember that an unbalanced concentration of additives can affect the properties of the oil. A porsche cayenne 201 price payer supposed to increase awareness. The use of commercial additives such as viscosity-enhancing or thickening additives and anti-friction additives are only recommended in vehicles with high mileage, worn out or that already require repair. Lubricating oils are made from mineral base oils plus an additive package. Additives are chemical products that are added to the base oil, the proportion varies and depend on the different types of oil; one of those with the largest amount of additive is gasoline or diesel engine oil.
