High loads as well as low displacement and great power, we’ll tell you where to find and what modern lubricants can do to protect modern engines.
Lubricant is an essential component of engine performance, and without it our impeller will last for a few minutes before it would succumb to an endless cycle of wear, friction, overheating, and melting of it’s internal organs . Additionally, it keeps the machine in good condition and helps prevent corrosion.
Imagine what the requirements are for lubricants in today’s engine designs, because they need to keep their characteristics in a harsher setting where weight and displacement are minimized, yet power and efficiency are enhanced . We make use of our experience with YPF’s production of its Elaion Lubricants which incorporate TAS(r) technology. It is which is an anti-stress component, to help you understand every aspect and problem that lubricants face in safeguarding your vehicle.
Lubricants should ensure their performance at the most crucial times for an engine that is cold start. They also aid in the ability to pump in any temperatures. The issue is that the quality decreases as time passes and large molecules are created, which makes the oil more dense. The latest TAS(r) techniques are developed to mitigate this degrading process to let the lubricant maintain the maximum molecular displacement capability, ensuring smoothness (or pumpspability ) as well as less stress on the engine upon beginning.
Viscosity as well as friction
This is where we begin to look at an issue. On one hand, lubricants should decrease friction through viscous and, therefore, not be so dense that components can move around freely. On contrary, they need to ensure that the film used for lubrication is in place even under the most difficult operating conditions, such as extreme temperatures or pressures that are high, as well as the an extremely high speed of relative motion between moving components (such as connecting rod bearings in an engine that is stressed).
The combination of viscosity and thickness is possible due to the proper mixture of additives and bases specifically designed to produce lubricants using the technology of anti-stress.
A majorly prone and vital places to lubricate the engine is the upper portion as it is one of the most distant areas from the pump that is as well, since it’s the initial area part from where the lubricant is drained when the engine is shut down. However, it is far from being the one that is most crucial for a high-loading mechanism such as the camshaft where the pressures required to overpower the tappets are massive and where – as a result of nature- it is not equipped with hydrodynamic oil lubrication.
In these conditions, the impact to the viscosity of the oil is minimal, and these antiwear components provide the biggest contribution working under high temperature and pressure inside the area of contact . In order to achieve that, TAS(r) technologies must be used to create an anti-wear coating of chemicals between plunger and the cam to prevent adhesion wear across both sides.
Corrosion and oxidation caused by urban traffic
The effects of high temperatures are negative on the lubricants used, and this isn’t just the case if you are driving at high speed however, it can happen in other situations like traffic jams during the summer season, where the engine has to be used for continuous starts and the volume of air entering the radiator is very small.
In these circumstances there is an natural process of the lubricant’s oxidation begins and progresses through diverse stages and impacts different parts of the impeller which includes the creation of acids that attack specific metallic compounds like bearings, producing molecules with high molecular weight that increase their viscosity as well as the accumulation of deposits that result in being found in the most hot parts within the engine such as the pistons.
The repeated stop-start-starting and start-up-starting of bottlenecks can also lead to the creation of sludge, or sludge during winter which leads to lower fluidity of the oil. If the lubricant is not contain the correct formulation, it can lead to an unfortunate fact: the wear of the components. In this case, anti-stress techniques make use of additives that have sufficient alkaline reserves with a high detergency as well as a great dispersing capability. Additionally synthetic bases provide the necessary security.
Savings on fuel
The lubricant should also meet the guidelines of several automakers in order to meet specific consumption targets . In this scenario an improvement in friction is crucial because of the choice and quality of the most advanced synthetic bases as well as additives.
Traditional fuels as well as biofuels with added certain characteristics that must be met by the fluid. For instance, bioethanol mixtures with gasoline could cause a more corrosive atmosphere because of the accumulation of acidic elements within the crankcase. Similar to this biodiesel engines which provide short-haul operations with continuous starts and stops could exhibit higher lubricant dilution because of the flow of fuel into the crankcase, thereby increasing the likelihood of deposits to form within the engine.
In both instances it is essential to use lubricant formulations that ensure proper control over corrosion, deposits and thermal degradation.
Less gas and oil after-treatment
Because of improvements in environmental protection, most modern motors use smaller amounts of oil and also include post-treatment systems for exhaust gas . This means that car manufacturers require a longer life of the lubricant as well as help to in reducing the consumption of fuel. Additionally, they need to be specifically designed for use in engines with posts-treatment for exhaust gases.
