Diesel Oil Classification and its Uses

Diesel engine oils are made up of several components, usually consisting of a base oil, viscosity modifier, and an additive package that could include antioxidants, pour-point depressants, detergents, and dispersants. You may be wondering which of these aspects are most important, which is why Oil & Energy has put together an educative guide that breaks down the basics of diesel engine oil and it’s uses.

Base Oil

The base oil forms the foundation of any diesel engine lubricant, serving as a binder for the total mixture. It is produced by means of refining crude oil, which is heated at different temperatures so that distillates can be separated from one another. The purest base oils are obtained by using hydrogenation technology, allowing for the proper removal of sulfur and aromatics. Chemical substances may then be added to the base oil so that it meets regulated quality standards for the product’s properties in relation to friction and cleaning.

Viscosity Modifier

Viscosity refers to the thickness and stickiness of an oil, also expressing the magnitude of internal friction – something that’s measured by the force per unit area resisting uniform flow. Viscosity is the most important factor for engine oil, as it must be carefully selected to ensure that targeted hydrodynamic lubrication can take place exactly when it is needed.

Additive Package

An additive mix is the key to ensuring a diesel engine oil meets global standards, among other significant performance criteria. Most, of course, are used to enhance the chemical and physical composition of the oil, allowing for the best possible lubrication.

So now that you know what diesel engine oils are made from, let’s take a closer look at their uses and benefits. Below is a list of the important functions it performs in a diesel engine:

• The reduction of wearing for components such as bearings, pistons, piston rings, cylinder liners, and the valve train.
• The reduction of friction for the boundary and hydrodynamically lubricated parts.
• Cooling of the piston.
• Preventing corrosion that comes from acids and moisture within the engine.
• Cleaning of the pistons and eliminating the risk of sludge build-up on internal surfaces.
• Lubricating seals and managing swelling to prevent leakage from seal failure.
• Aiding components in vehicles with HEUI (Hydraulic Electronic Unit Injector) fuel systems.
