High loads as well as low displacement and great power, we’ll tell you about the places and what modern lubricants can do to protect most modern engine
Lubricant is essential to engine performance, and without it our impeller will last for a few minutes before succumbing to an avalanche of wear, friction overheating and melting it’s internal organs . Additionally, it keeps the machine in good condition and stops corrosion.
Imagine what the requirements are for lubricants for the latest technology engines, as they have to maintain their properties in a higher stress setting where weight and displacement are decreased, however the power and efficiency increase . We draw on our experience with YPF’s production of its Elaion Lubricants, which include TAS(r) technology. It is which is an anti-stress component, to help you understand each component and every issue that lubricants face in safeguarding your vehicle.
Cold Start
Lubricants have to ensure their effectiveness in one of the most crucial times for an engine that is cold start. They also aid in the pumping capability in all 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 designed to counteract this degradation and let the lubricant maintain the maximum molecular displacement, which means the fluidity (or the ability to pump ) as well as less stress on the engine during the time of start-up.
Viscosity, friction and even friction
We begin with an issue, on one hand, the lubricants need to 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 can be achieved through an appropriate mixture of additives and bases specifically designed to produce lubricants using Anti-stress technologies.
Camshaft
A majorly vulnerable and vital places to lubricate the engine is the upper portion as it is one of the areas that is farthest from the oil pump as well, since it’s the initial area part from where the lubricant is drained when the engine ceases to run. However, it is in no way the topmost important for a high-loading mechanism such as the camshaft in which the pressures to overpower the tappets are massive and where – as a result of nature- it is not equipped with hydrodynamic fluid lubrication.
Under these conditions , the effect to the viscosity of the oil is negligible, whereas those additives to prevent wear contribute the biggest contribution working under extreme temperature and pressure within the zone of contact . To achieve that, TAS(r) technologies must be utilized to form an anti-wear layer of chemical between plunger and the cam and plunger, which prevents the wear of adhesives between the two surfaces.
The corrosion and oxygenation caused by urban traffic
Temperatures that are high can have adverse effects on lubricants. This isn’t just the case if we are operating at high speeds as well as in conditions like traffic jams in the summer months, when the engine has to be used to run continuously and the volume of air entering the radiator is limited.
In these circumstances there is the 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 certain metallic compounds, like bearings, producing molecules with high molecular weight that enhance their viscosity, and the development of deposits that will result in being found in the most hot parts within the engine which includes the pistons.
heavy traffic
The repeated stop-start-starting and start-up-starting of bottlenecks may also result in the creation of sludge, or sludge during winter which leads to lower fluidity of the oil. If the lubricant doesn’t contain the correct formulation, it can lead to an unsettling fact: the wear of the components. To prevent this, anti-stress technology make use of additives that have sufficient alkaline reserves 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 most advanced synthetic base and additives.
Biofuels
Conventional fuels and biofuels that have 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 build-up 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 fuel entering the crankcase and increasing the potential for deposits to form within the engine.
In both instances it is crucial to choose lubricant formulations which allow for the proper control of corrosion, deposits and thermal degradation.
Less gas and oil after-treatment
Thanks to advances in environmental health, most modern motors use less oil that circulate and include post-treatment systems for exhaust gas . This is why car manufacturers need a longer-lasting lifespan from the lubricant as well as help to reduce the amount of fuel consumed. Additionally, they need to be designed specifically to be used in vehicles equipped with posts-treatment for exhaust gases.
