- Every time you crank up the internal combustion engine of your two-wheeler, there are countless explosions taking place inside the cylinder, which, along with the frictional forces of the various moving parts inside, generate a tremendous amount of heat. Engines convert energy produced by the burning of the fuel into mechanical energy; in our case it is into turning of the wheels. But not all the energy generated by combustion is converted into mechanical energy, the big chunk gets dissipated as heat energy. As we try to run the engine on higher revs, higher amount of heat is generated (due to friction between mechanical parts) which results in heating of the engine.
How Engine Cooling Water System Works - In HINDI : • How Engine Cooling Wat...
For a smooth running of the engine as well as to maintain an optimum performance, the engine needs to be cooled down, and this where the ‘cooling technology’ comes into the picture. There are three categories we can classify engines based on the cooling method employed…
1. Air cooled Engine
2. Oil Cooled Engine
3. Liquid cooled Engine
1. Air cooled Engine
This is the most basic method among the three where the natural air is used as a cooling agent. The working principle is pretty straightforward, where the outer casing which houses the engine cylinder is surrounded by fins that create channels for passing air to take away the heat dissipated by the happenings inside. The fins also increase the surface area, of the casing, allowing the heat to dissipate quickly. Air cooling is a cost-effective method but it isn’t the most efficient choice for high-performance engines which rev high and can generate a lot of heat.
If engineered well, it’s quite a reliable method for cooling though, as there are lesser things to go wrong which would otherwise affect the working of an engine. This method is usually adopted for small capacity engines which generate a modest amount of power and resultant heat. Air cooling is also used for large capacity engines which do not rev too high. However, large capacity air-cooled engines work best in colder climes as the heat generated near the rider’s legs makes the motorcycle troublesome to ride during hot and stop-go conditions.
2. Oil cooled Engine
This is the intermediate option which is deployed to keep engine temperature in check. In addition to adoption of air cooling as discussed above, this method also makes use of an oil cooler which cools down the temperature of the engine oil. The engine oil which is circulated within the engine when its running absorbs the heat generated inside and beyond a defined temperature level begins to lose its viscosity. As the density of the lubricant decreases, friction between the internal components spikes and as a result, engine temperature too begins to shoot north.
To avoid this, and to make sure that the engine oil maintains an optimal operating temperature, it is circulated between ‘oil cooler’. This mechanism too makes use of atmospheric air to cool down the engine oil which passes through a radiator-like, externally mounted oil cooler. As there is already an oil circulation system available for lubrication, this oil is also piped to the cylinder head and used as a liquid coolant. Compared to an oil system used solely for lubrication, oil cooling requires additional oil capacity and a greater flow rate through the oil pump.
Oil cooling is an ideal method for engines where air-cooling is sufficient for much of the running time, but an additional amount of cooling is required for a specific performance range, where it is vital that the engine oil retains its viscosity and minimizes friction. However, since atmospheric passing air is still the basic element used, where cooling improves only when speed rises, oil cooling is not as efficient as liquid cooling and cannot be installed on high-performance engines that produce huge amounts of heat during all operating conditions.
3. Liquid cooled Engine
This is the type of cooling method used in large capacity motors since they rev high, generate higher amounts of power and require ideal cooling during all operating conditions. The concept of liquid cooling for a motorcycle engine is similar to cars, where a coolant is circulated through internal channels around the motor. Because the coolant absorbs the heat from the engine, its own temperature must be brought down. As a result, it is pumped towards a radiator which cools it down using atmospheric air and additional fans which activate when the vehicle is moving at slow speeds.

I asked a mechanic what's the speciality of liquid cooled engine and what's the difference between air cooled and liquid cooled engine,he told me the difference between liquid cooled engine and air cooled engine,and he told me the advantages of liquid cooled engine,he told me that in liquid cooled engine bike,the engine is not at all dependent on outside atmosphere for its source for cooling,and the coolant in radiator is capable of cooling itself,and you can ride the liquid cooled bike non stop for over 200 kilometres regardless of weather conditions,whereas air cooled engine are dependent on outside weather,if weather is extreme hot,we should take break in every 40 km ride but if the weather is cold, then you can still ride the bike for continuous 70 km,and one should always take a break of 15 minutes in every 50 km ride in air cooled engine bike,if we don't do,there is chance that engine may get seize, whereas there is no such threat in liquid cooled engine bike,even TVs company is installing liquid cooled engine in the 159cc TVs Apache
Apache is air/oil cooled...
It is funny to see how some people call engine oil as Mobil 😜 It is like replacing toothpaste with colgate
Just like you call Photocopy 'xerox'
👍
huh Toothpaste is a just a Toothpaste but Colgate is a brand name itna to fark pata hona chahiye apko Toothpaste kisi b brand ka ho skta h Colgate k aur b bahut si cheeje ati h iska Matlab kya wo sab Toothpaste h how funny 🤣🤣🤣

Advance congratulations for 1M family ❤️🇮🇳
Thanks for the support ❤
Because of low compression ratio that is approximately 8.5:1 the 350cc monster produces less heat as compered to other high compression ratio bikes like R15,Duke all models which have nearly 12:1 compression ratio, and here much heat produced during combustion of air-petrol mixture thats why R15, Duke have liquid cooling system and the other hand Royal Enfield have simple air Colling engine which is enough to cool up the munster
No satisfaction of any topic without seeing the video of this channel. 👆

Royal Enfield mein Air Cooled hota hai fir bhi kabhi heat nhi hota . Air cooling thik se ho toh oil cooled se zyada effective hota hai. Oil cooled toh actually separate air cooling for engine and engine oil ho gaya .
Bhai mai classic 350 owner hun .. kya bol rhe ho heat nhi hota.. bullets to maani jati h heat create krne k liye.. kch km mai hi omlete tayar kr skte h engine surface pe😂
@@royalrider3225 right
Mere paas bhi re classic 350 bs6 hai, 10 km bhi chalate he to bhi omlet ban jaye itna heat hota hai 😂😂😂
VERY GOOD ENGINEER SIR WELL EXPLAINED THANK YOU
Thank you so much sir .for this kind information 😘
Aapki knowledge kamaal ki hai
Is it possible to utilize this heat some how....?
May be for efficiency or in other functional work....
Or anything like use....
I don't think so
Yes, U can utilize the heat by having the exhaust run a turbocharger and pressurize the intake manifold to give the engine a denser air/fuel mixture.

Bhaiya aap ka ye video mujhe bahut aacha laga
For an average, between 200 to 500 cc bikes ..oil cooled still the best in India
No... In bikes like ktm with high power in low cc, u need liquid coolinga
In MT 15 and R15 u will need liquid cooling; their compression ratio high...
Very informative... Thank you
Tq sir ap buri bath bohoth ache samjadethe hain super

Boss Royal Enfield bike k 350 cc bike my bhi air cooled engine use hota hai
But why
Nice video bro,
My question is that I have bajaj pulsar 150 bike, in that timing chain need to replace after every 3-4 service. Is there any solution?
It's totally depend on you how u drive how u mantain
Change your mechanic, dont go at showroom
@@vish5718 right brother
Even the Indian, Harley davidson's bikes 🏍 comes with air cooled engine
Lol... Its not a performance motorcycle bro... Harley davidson is just royal enfield of USA.. No real perfor. Ance, highly underpowered, and mostly impractical as a perfor. Ance bike... Even the engine type of RE, harley is same which is undersquare long stroke engine which is old technology ...... See all sports bikes, no bike has air, oil cooled
@@starscream1457 magar fir bhi fast bahaut hai vo bikes Harley ki
But haan almost every modern retro cruiser bikes comes with air-cooled expect boss hoss and honda kawasaki retro
@@starscream1457 impractical bhai zayada ho raha hai impractical toh mujhe vo lean waali sports bike lagti hai kyaa fiada back pain 🙄 no long rides no commuting like city rides daily shopping many more naked chalo fir bhi sahi hai
Why bullet standard 350cc only has air cooled engine system except there is high power in engine?
Right question bro, because of low compression ratio that is approximately 8.5:1 the 350cc monster produces less heat as compered to other high compression ratio bikes like R15,Duke all models which have nearly 12:1 compression ratio, and here much heat produced during combustion of air-petrol mixture thats why R15, Duke have liquid cooling system and the other hand Royal Enfield have simple air Colling engine which is enough to cool up the munster. I think you may clear now

Haan kar sakte hai, Duke 125 me bhi hai na liquid cooling, MT15 me hai aur ns200 me hai liquid cooling.
Or apne bahut achi tarh explan kiya h
Does it bring any benefit to add a fan (intervention controlled in temperature) to the oil cooler of the RE Interceptor 650? Tks
konse engine ka life jyda aur accha hota hai...
