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 modern engines.
Lubricant is an essential component of engine life. Without it, our impeller will last for a few minutes before succumbing to an avalanche of wear, friction overheating and melting the internal organs . Additionally, it keeps the machine in good condition and helps prevent corrosion.
Imagine the need for lubricants in today’s engine designs, because they have to maintain their properties in a higher stress setting where weight and displacement are decreased, however the power and efficiency increase . We make use of the experience of YPF in the development of its Elaion Lubricants, which include TAS(r) technology. This is which is an anti-stress component, to help you understand every aspect and problem that lubricants face in safeguarding your vehicle.
Cold Start
Lubricants have to ensure their effectiveness in one of the most crucial instances for engines 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 form, making the oil more dense. The latest TAS(r) techniques are designed to mitigate this degrading process to let the lubricant keep the maximum molecular displacement, which means smoothness (or pumpspability ) which reduces wear and tear on engines upon 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 which means that they should not be so thick that the parts can’t move; on another hand, they need to ensure that the film used for lubrication is in place even under the most difficult operating conditions, such as extreme temperatures as well as high pressures, and a an extremely high speed of relative motion between moving components (such as connecting rod bearings in the engine with high stress).
The combination of viscosity and thickness is possible due to an appropriate mixture of additives and bases specifically chosen to create lubricants that have Anti-stress technologies.
Camshaft
The most prone and vital places to lubricate the engine is the upper portion due to it being one of the most distant areas from the oil pump and , in addition, it’s the initial area place from where the lubricant is drained when the engine ceases to run. However, it’s in no way the topmost crucial for a heavily loaded mechanism such as the camshaft in which the pressures to overpower the tappets are massive and where – as a result of nature- it does not have hydrodynamic fluid lubrication.
Under these conditions , the effect to the viscosity of the oil is minimal, and these antiwear components contribute the biggest contribution working under extreme temperature and pressure inside the area of contact . In order to achieve the above, TAS(r) technologies must be utilized to form an extra-sealing layer of chemical between plunger and the cam to prevent adhesion wear across both sides.
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 however, it can happen in other situations like traffic jams during the summer season, where the engine has to be used to run continuously and the volume of air entering the radiator is very small.
In these circumstances there’s an natural process of the lubricant’s oxidation starts and progresses through diverse stages and impacts different parts of the impeller which includes the creation of acids that attack certain metallic compounds, like bearings, resulting in molecules with high molecular weight that enhance their viscosity, and the accumulation of deposits that are then found in the most hot parts within the engine such as the pistons.
heavy traffic
The constant starting-stop-starting action of bottlenecks can also lead to the development of sludge or sludge during winter which leads to less fluidity for the fluid. If the lubricant doesn’t have the right formulation, it can lead to an unsettling fact: the wear of the components. In this case, anti-stress techniques use additives that offer sufficient alkaline reserves that is highly effective in detergency and dispersing capabilities. Additionally synthetic bases offer additional security.
Savings on fuel
The lubricant should also meet the specifications of a variety of automakers in order to meet specific consumption objectives . In this scenario an improvement in friction is crucial because of the selection and the quality of the latest generation of synthetic base and additives.
Biofuels
Traditional fuels as well as biofuels with the addition of biofuels have specific certain characteristics that must be met by the fluid. For instance, bioethanol combination with gasoline may cause a more corrosive atmosphere because of the accumulation of acidic elements within the crankcase. Similar to this biodiesel engines, which perform shorter-haul service with continuous start and stops could exhibit higher lubricant dilution because of the fuel entering the crankcase and 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.
Gas and oil are not included after-treatment
Thanks to advances in environmental health, most modern motors use smaller amounts of oil and also include post-treatment systems for exhaust gas . This is why car manufacturers require a longer lifespan from the lubricant as well as help to in reducing the consumption of fuel. Furthermore, they should be designed specifically to be used in vehicles equipped with the exhaust gas post-treatment system.
