What is Engine Oil? What are the applications? What are the Types? How to select the right product for your Engine?


Engine oil are basically oil extracted from crude oil, which are slightly inflammable in nature used in engines for smoother operation, due it is higher viscosity in nature. Nowadays synthetic technology has been introduced in processing the oil, which uses a covalent bonding technology. 

Engine Oil are primarily used for the lubricating the shaft / piston movement of the engine. As the engine runs lots fo heat energy is generated due to the frictional movement. Engine oil are basically acts as a medium to reduce the friction between the metal parts and also cools the moving parts by absorbing the heat. Thereby it reduces the wear and tear losses and further enhances the engine performance. 

Basically engines are classified into two categories i.e. 2 Stroke and 4 Stroke Engines. Engines with smaller capacities or compact power generators / diesel generators use a two stroke engine, whereas the engines with capacity above 100 cc like motorcycles and scooters uses 4 stroke engines. A two stroke engines operates with one up and down cycle for one movement, whereas a four stroke engine uses two up and down piston movement for one rotation. Thereby a four stroke engine has higher power and rpm when compared to a two stroke engine. 

2 T engines are manufactured without any oil reservoir or storing unit. Hence a 2 T engine oil is added along with the fuel, which possess a characteristic of burning along with the fuel, as these possess a tendency of lower viscosity and slightly flammable. 4 T engine oils are manufactured for engine heads which has a separate unit for storage where the Gear Box, Timing unit and Clutch plate assembly are present apart from the cylinder / piston head which has been isolated in between the Clutch and Gear box assembly. 

Engine oil shall possess a characteristic’s to operate under extreme climatic conditions. Usually the nominal operating temperature is designed considering the ambient temperature. For instance the ambient temperature of our ecosystem lies between – 30 deg C to + 55 deg C. The engine oil has to be produced considering the tolerance limit of 30 to 40% thereby produced to withstand the geographical climate conditions between – 45 deg C to 100 deg C. Engine oil are specified in numerical numbers in xx W-yy format. The first two digits represent the operational temperature in winter / colder temperature whereas the next two digits represent heat withstanding capacity. For instance 00 W – 10 specifications refers to operate in extreme colder condition / colder start up as the engine oil will remain to operate / neither solidifies in colder climate. As the engine heats up due to friction, the operating temperature of the engine designed at 100 deg C, thereby acts as a cooling medium to the heat that generated. The key point is thaty the viscosity of the remains unchanged when heated up due to friction. 

So if you are having a stroke stroke engine is advised to use the engine oil added up with the fuel. For four stroke engines the specifications ranges from 05 W – 20, 10 W – 30, 15 W – 30 and 20 W – 40 are the most commonly available standards. Typically scooters don’t have gear box assembly neither a clutch plate assembly, which means the lesser heat generation. So the lower heat withstanding capacity will be sufficient. ie. 20 or less than 20 for the operating temperature range. The ideal standard shall be 05 W – 20 is advised for four stroke scooter models, for areas where the atmospheric temperature shall not drop below 20 deg C. For engines with Gear and Clutch assemble typically bikes, the operational temperature shall be higher than the normal scooters hence the 40 rated oil is advisable for the operations. i.e 10 W – 40 or 15 W – 40 or 20 W – 40 is advisable for the bikes. The most advisable spec for the Southern states climatic regions of India is 10 W – 40

Hydroponics என்றால் என்ன? அது எதற்கெல்லாம் பயன்படுகிறது? What is hydroponics and where it is applied?

Hydroponics   என்பது   இப்பொழுது   வளர்ந்து   வரும்   ஒரு   தொழில்நுட்பம்.   சுருக்கமா   சொல்ல   போனால்   மண்ணில்லாத   விவசாயம் .  என்னங்க  Technology  புதுசா   இருக்கா?   விவசாயம்   என்றாலே   மண்   இருந்த   தானே   செய்ய   முடியும்.   சரி அது எப்படி மண் இல்லாமலே விவசாயம் பார்க்க முடியும் என்று பார்ப்போம் .  செடி அல்லது பயிர் வளர்வதற்கு மண்ணில் உள்ள தாதுக்கள் மண் வளம் மற்றும் தண்ணீர் தானே தேவை .  இபொழுது செயற்கை உரம் என்று பலவற்றை பயன்படுத்தி மண்ணை மலடி ஆகி விட்டோம் . தண்ணீரிலே அணைத்து விதமான தாதுப்பொருட்களும் உள்ளது , இதை பயன்படுத்தி விவசாயம் அல்லது பயிரை அல்லது செடியை வளர்ப்பது தான் Hydroponics.  இதை எப்படி செய்வது என்று பார்ப்போம் .  இதை செய்வதற்கு நமக்கு தேவையானவை Rock Wool Slab எனப்படும் கண்ணாடி பஞ்சு Slab கள் .  முதலில் இந்த Rock Wool Slab கள் Sheet போன்ற வடிவத்தில் இருக்கும் .  ...

Attapady – A overview of a Hill Village to have travel experience at Tamilnadu Kerala border

Coimbatore is a Manchester of South India and it is located at the foothills of the Queen of Mountains (Nilgiri). It is surrounded by Rivers, Ponds and Agro Fields and it one of the few cities across globe which has a pleasant atmosphere to live in. Further the outskirts of Coimbatore is surrounded by Valparai Hills and Coconut farms at the one side and Kerala – the god’s own country at the other side. There are multiple places to visit around Coimbatore and this blog is about an adventure trip around Coimbatore.  I just wanted to experience some adventure so without clue I started travelling to Karamadai, a place close to the Niligiri foothills, to visit the village called Baralikadu to experience river boating and village fooding. As the day I travelled is in between the week and I was informed by the forest department that the program is only planned on weekends. So without frustration I have started to travel further and reached a placed called Tholampalayam, where I have a...

What is Castable Refractory? Where it is applied? What are the applications?

Castable Refractory is the High temperature refractory materials that are made up from rare earth minerals. These castable refractory are composites of Minerals and Oxides of the Minerals. The materials are primarily extracted from the mines as ores and are processed for the end use application. Typically extracted from mines, which possess a characteristic as a barrier for thermal conduction. Basically serves as Thermal Insulators and thus enacts fuel saving.  Heat is the fundamental source of energy for most of process, either in domestic or industrial segment. The most commonly used heat applications in domestic segment is Cooking, Room Heating, Ironing, Hot Water and Drying. In the Industrial segment, it has varied applications in most of the Industries widely as Boilers, Furnace and Dryers. The amount of heat energy consumption is almost equal to the consumption of electricity for any industry and typically we use 1/3rd of our energy utilization as Thermal energy. Fuels like F...
