Bio-lubricants for Tropics to Save Energy and EnvironmentOleg Kulikov
Engine oil is comprised of a base fluid enhanced with additives. We developed a novel bio-based additive pack for engine oils. It comprises neither Sulfur nor Phosphorus and enables application of palm olein as a base fluid for tropical countries. Such bio-oil enhances fuel economy of an engine up to 30% and radically extends longevity of the engine as wear rate can be 25-50 (!) times slower in comparison with the best synthetic engine oils. We work on similar bio-oils for countries with moderate climate too.
The lubrication system reduces friction, wear, and heat in engine parts. Oil is pumped under pressure to bearings and flows through channels to lubricate moving components like the crankshaft, pistons, and valves. Additives are included to improve properties like viscosity and detergency. Systems range from simple splash lubrication to more advanced wet and dry sump systems with scavenge pumps. The oil filter removes impurities and gear-type pumps are commonly used to pressurize oil for circulation. Proper lubrication is essential for engine performance and longevity.
The document discusses lubrication systems in internal combustion engines. It defines lubrication as applying a substance like oil or grease to minimize friction and allow smooth movement. There are three main types of lubrication systems - mist, wet sump, and dry sump. Wet sump systems use an oil sump at the engine base and either splash or pressure pumps to circulate oil. Dry sump systems store extra oil outside the engine and use scavenging pumps to circulate it through the engine and an external heat exchanger.
Titled as 'Automotive Tribology ", the concept of this poster presentation was to enlighten my fellow college persons to know the diagnosis/abbreviations behind lubricants used at automotive.
We happen to share our knowledge on this field to many onlookers simultaneously enhancing their bond towards this Tribology field and improving my communication skills.
1) Proper engine lubrication is important to prevent friction and wear between moving parts. It is essential to use the correct type and weight of oil and regularly change it as recommended.
2) There are three main types of engine lubrication systems - circulating splash, internal force feed and splash, and full internal force feed. Modern engines primarily use the full internal force feed system.
3) Engine oil serves several critical functions including reducing friction, sealing cylinders, removing heat, cleansing the engine, and absorbing shocks. Proper lubrication helps engines run smoothly and prolongs their lifespan.
MULTILUBE XKE is an oil additive that can be added to motor oils, gear lubricants, hydraulic fluids, and transmission fluids. It helps maintain film strength to protect engine parts from wear. MULTILUBE XKE boosts viscosity and lubricity while cleaning deposits from engines.

Lubricants such as oils, greases, and other substances are used to reduce friction between moving parts and prevent wear. There are various types of lubricants including mineral, synthetic, vegetable, and animal-based. Oils are used for lubrication through boundary, hydrodynamic, and elastohydrodynamic methods. Greases are also used for lubrication and provide advantages over oils by remaining in contact with moving surfaces longer. Synthetic lubricants were developed to withstand higher operating temperatures than petroleum-based lubricants. Proper lubricant selection and maintenance is important for optimal machinery performance and longevity.
Engine lubrication begins with oil pulled from the sump through a filter, then distributed throughout the engine via passageways to components like bearings and pistons. Lubricants contain additives like detergents that suspend harmful deposits in the oil to prevent damage. A multi-grade oil uses viscosity index improvers that allow it to flow easily at cold temperatures but maintain thickness at higher engine temperatures. Regular maintenance like oil changes is necessary to prevent additive depletion and lubrication breakdown from contamination, overheating, or long drain intervals.

1. What is the thickest diesel engine oil?
Thickness of an oil usually depends upon the grades. Oil grades are related with
the performanceof oil product’s performancewhich is found at operating
temperature. Diesel engines are commonly rated between 15W-40 and 5W-40.
The number which comes beforeW stands for the thickness of the oil when it is
on the cold temperature and the number which comes after W reflects the oil’s
thickness when it is at normal operating temperature. The thickness of an oil is
more commonly referred to as viscosity grade. Viscosity is a measureof a fluid’s
resistanceto flow. Itactually describes the internal friction of a moving fluid.in
simpler words oilviscosity refers to how easily oil flows at a particular
temperature. The oil that has lower viscosity arethinner in comparison with the
oils that has higher viscosity grade. Higher the viscosity thicker the oil. Itis
believed that thick oils are better at maintaining film strength and oil pressureat
high temperatures and loads. This oil is majorly made for the rare cars which are
with diesel engines that burns oil excessively. Itis a premium high performance
mineral.
Features and Benefits of thickest Diesel Engine oil:
This oil is majorly made for the rarecars which are with diesel engines that burns
oil excessively. Itis a premiumhigh-performancemineral. Itprovides non friction.
Iteven features a double layer of engine wear protection with full zinc. This helps
to protect the engine againstcorrosion, oiloxidation and sludgeunder all
operating conditions. This oil is particularly suited for useunder high load
conditions such as towing and competition. Itis basically designed for use where
the ambient temperatures are higher. Itis even suitable for the engines that
shows signs of excessiveoil consumptions. Italso helps to providea better
protection for older worn engines that needs a heavier viscosity engine oil so that
it can maintain the oil pressure. Itis also suitable for passenger cars and heavy-
duty commercial vehicles. Along with all of these such oils are also suitable for
industrial and agricultural machinery. Ithelps in lowering the frictional heat which
results in improving the engine oil film strength. It also provides an extra layer of
anti-wear protection and reduces the engine wear in all driving conditions. The
presenceof zinc in this oil helps in the engine wear protection. This oil has fast
2. acting formulation which works really swiftly. Itprolongs enginelife. Reduces high
temperature engine deposits. Such thick oils are not recommended for common
engines and using a heavier gradethan recommended may causedecrease in fuel
economy, higher engine loads and eventually may result in shortened engine life.
On the other hand, using a lighter grade than recommended may result in
excessivemechanical wear and reduced engine life. So, for the best engine
performancethe recommended oil viscosity should befollowed. In some
situations, thicker oil can be used to compensate for increased bearing clearances
that have developed over the years and a large change in bearing clearances can
result in poorer lubrications.
