What are the functions of engine oil?

High loads as well as low displacement and great power, we’ll show you where to find and how modern lubricants safeguard the modern engines.

Lubricant is an essential component of engine performance, and without it our impeller could last for minutes before it would succumb to an endless cycle of wear, friction, overheating, and melting of it’s internal organs . It also keeps the machine in good condition and stops corrosion.

Imagine what the requirements are for lubricants in today’s technology engines, as they need to keep their characteristics in a higher stress environment where displacement and weight are minimized, yet power and efficiency are enhanced . We draw on our experience with YPF’s production of its Elaion Lubricants, which include TAS(r) technology. This is which is an anti-stress factorto describe each component and every issue that lubricants face in keeping your engine safe.

Cold Start

Lubricants should ensure their performance at the most crucial times for an engine such as cold start, which is facilitating the ability to pump in any temperatures. The issue is that the quality decreases with time, as larger molecules form, making the oil harder. The latest TAS(r) techniques are designed to mitigate this degrading process to let the lubricant keep the maximum molecular displacement capability, ensuring the fluidity (or pumpspability ) which reduces wear and tear on engines upon the time of start-up.

Viscosity as well as friction

We begin with an issue, on one hand, lubricants should decrease friction through viscous and, therefore, not be so dense that parts can’t move; on another hand, they need to make sure that the lubricating layer remains constant even in the most extreme operating conditions such as extreme temperatures as well as high pressures, and a fast relative speeds between moving components (such as connecting rod bearings in the engine with high stress).

The combination of viscosity and thickness can be achieved through the proper mixture of bases and additives that have been specifically designed to produce lubricants using Anti-stress technologies.

Camshaft

A majorly vulnerable and vital places to lubricate within the engine is the upper portion as it is one of the most distant areas from the oil pump as well, since it’s the initial area place from the point where the lubricant drains after the engine ceases to run. However, it’s far from being the one that is most important for a high-loading mechanism such as the camshaft where the pressures required to surpass the tappets are high and – by nature- it does not have hydrodynamic fluid lubrication.

In these conditions, the impact to the viscosity of the oil is negligible, whereas these antiwear components provide the largest contribution working under high temperature and pressure inside the area of contact . To achieve that, TAS(r) technologies must be utilized to form an extra-sealing coating of chemicals between plunger and the cam to prevent adhesion wear between the two surfaces.

The corrosion and oxygenation caused by urban traffic

Temperatures that are high can have adverse effects on the lubricants used, and this isn’t just the case if we are operating at high speeds as well as in conditions like traffic jams during the summer season, where engines are required to run to run continuously and the volume of air that gets into the radiator is very small.

In these circumstances there’s an natural process of the lubricant’s oxidation starts and progresses through multiple stages and affects various parts of the impeller and the development of acids that attack specific metallic compounds like bearings, producing high molecular weight compounds which enhance their viscosity, and the accumulation of deposits that are then found in the hot areas within the engine which includes the pistons.

heavy traffic

The repeated starting-stop-starting action of bottlenecks can also lead to the creation of sludge, or sludge during winter that results in lower fluidity of the fluid. If the lubricant is not have the right formulation, it will result in an unsettling fact: the wear of the components. To prevent this, anti-stress technology use additives that offer an adequate reserve of alkaline that is highly effective in detergency and dispersing capability. Additionally synthetic bases offer additional security.

Savings on fuel

The lubricant should also meet the guidelines of several automakers in order to meet specific consumption targets . In this scenario the reduction in friction is crucial because of the choice and quality of the latest generation of synthetic base and additives.

Biofuels

Conventional fuels and biofuels that have the addition of biofuels have specific certain characteristics that must be met by the oil. For instance, bioethanol combination with gasoline may cause a more corrosive atmosphere because of the accumulation of acidic substances within the crankcase. Similar to that biodiesel engines, which perform shorter-haul service with continuous start and stops could exhibit more lubricant dissolution due to the flow of fuel into the crankcase, thereby increasing the potential for deposits to form within the engine.

In both instances it is crucial to use lubricant formulations that ensure proper control of corrosion, deposits and thermal degradation.

Gas and oil are not included after-treatmen

Because of improvements in environmental health, most modern engines use less oil that circulate and include post-treatment systems for exhaust gas . This is why car manufacturers need a longer-lasting life of the lubricant as well as help to in reducing the consumption of fuel. Additionally, they need to be specifically designed to be used in vehicles equipped with the exhaust gas post-treatment system.
