water cooled engines are superior due to higher compression, more power better gas mileage longer lasting by far. My first 2 bikes were air cooled and shook and vibrated badly by 20000 miles even with frequent oil changes. My next and all subsequent bikes are water cooled can ride 50000 miles no change in vibration no smoking out the exhaust no need for early overhaul. Also far fewer emissions. I don't like smelling the exhaust- if your bike has efi and water cooling then you won't- but its important that the bike cools well, runs around 170 degrees even in hot weather.
On high specific output engines with four or five valves per cylinder, liquid cooling is mandatory. The reason is that the cylinder head is almost completely filled up with valve pockets/ports as well as spark plug well and maybe even fuel injector. This leaves no space for cooling fins plus the fact that the high output engine is generating more heat per cylinder. Air cooling simply can't pull the heat out of the engine fast enough, so overheating and engine failure would be the inevitable result. Another advantage of liquid cooling is that the engine can maintain a narrower range of operating temperature over different conditions, so the designers can specify finer tolerances for the piston/cylinder which results in better efficiency and more power. Air cooling is best for simple engines of more modest power output. Before someone brings up aircraft engines, they are two valve, pushrod engines of relatively low specific output. Big displacement for the power produced.
I don't understand why liquid cooling is less efficient in smaller engines at the end of the day a liquid cooling system transfer the heat more efficiently so why not use it in a low capacity engine can you elaborate more on that? Thank you!
Main reason why most lower displacement engines dont use liquid cooling is because its expensive to manufacture and smaller displacement engines dont typically need it
Not a joke: What if you get some small copper tubing (outside diameter close to the gap between cooling fins) and wound it tightly around the head and between the cylinder air cooling fins? Then added a fan cooled radiator from ebay and a small electric water pump. I wouldnt want to decrease air flow to the fins, but i also think the copper and cooled water would dissipate heat faster than just air cooling. In theory the copper would also be slightly air cooled as well. This would be used in conjunction with an oil cooler. Thoughts anyone?
I don't think that would be close to as effective as water cooling. I'd rather try an oil cooler. I've always wondered if royal enfield int 650 with oil cooler could last as long as a comparable water cooled engine if the oil is kept also at 170 degrees. I highly doubt it but wonder. Air cooled engines can never be as good as a water cooled engine even if, however, because compression ratio is a lot lower then similiar water cooled engine. This means less gas mileage less power at minimum for the air cooled engine.
If you must use water in freezing weather just make sure you drain it all out before you leave the engine. Then put it all back right before you start it.
bro tell mee pls i wanna buy a 10hp diesel engine for generator ...but m confuse between air cooled and liquid so pls tell which one will be better...aircooled or water....??????
yes you can, but when engine start overheating it will boil that water and can damage your engine, at low temp it will freeze therefore it also can damage your engine and your coolant, just use a specific one ok? it for your own good
Pure water can also rust internal cooling components such as your water pump. liquid cooling engines usually benefit from a mix of anti freeze coolant agent and water. Search your vehicle's manual for that info for the most reliable solution
For short trips liquid cooled engines will dilute the oil with fuel and water condensation. As its not able to get hot enough to burn off. Air cooled doesn't have this issue and better for a life of short trips. Also you don't risk blowing a head gasket if it does get hot.
There's never a situation when air cooling is superior to water cooling. Air cooled engines are cheaper and take up less space. Only advantages for air cooling. Water cooled engines, kept cool 170 degrees or less basically last forever if a decent design. No air cooled engine lasts forever. Our 1937 John Deere Model B is more than 80 yrs old runs 150 or 160 water temp all day long, has never had its crankshaft see the light of day. Never overheated or blown a head gasket. Never adjusted the valves! Polaris ranger more than 20 years old runs 170 all day with water temp gauge never smokes never over heated. I think I made my point here!
@@j.d.mcginn6946 except you failed to acknowledge other aircooled benefits such as you will not be left stranded if you loose your coolant or blow a headgasket which isnt uncommon.
But if you keep the water temp at 170 degrees as I've said many times- radiator hoses last far longer- in fact I've never blown one. Never overheated, ever, in any or my vehicles. But i always rebuild their radiators. On my jeep grand cherokee it was running 240 degrees in 100 degree weather! Absolutely rediculous. I changed the radiator from 1" thick to 2.5" thick! Now it's far better never over 190. Still not good enough for me so if I bought another jeep grand cherokee I'd get the V6 since I know I cam keep it cool. The radiator would be even thicker but I'd get the performance I want.
@@j.d.mcginn6946 If we are talking cars, 4wds yeah id only want liquid cooling for internal combustion for sure. But for poorly treated motorcycles for offroad expeditions, farm work, traveling thru Africa or something id totally go a japanese aircooled motorcycle where you have everytool required with the included toolkit to service any part of the bike short of a rebuild.
Wouldn't be for me. The single cylinder air cooled bike would soon vibrate so bad I wouldn't be able to ride it. I'd modify the water cooled one so that in 120 degree desert weather it still runs 170. It would be a far more refined machine that again would last forever.
You still get air cooling on a water cooled motorcycle with the fins. So, you get the two going for you. Also, oil is still going to be cooler on my motorcycle due to the two air/water combination.
Simple and very good explanation..
It is very efficient in small engines too. I have seen many air cooled pistons stopped working after a lot of mileage
liqwicked the way to go eh
Yes i have a 125cc liquid cooled engine produce a good hp and torque
Some small engines are more efficient when they're liquid cooled. Race bikes have been doing it for decades

Might be because it weighs down the engine/vehicle too much for it to be worth it.
Main reason why most lower displacement engines dont use liquid cooling is because its expensive to manufacture and smaller displacement engines dont typically need it
It's more expensive to manufacture. All engines perform better water cooled even small ones.
@@j.d.mcginn6946 Ah good to know thanks.

Hi Bro @techtrixinfo can you tell why liquid cooling is not suitable for smaller engines?
Is there anyone giving the thumbs up and/or positive comments to this guy who isn't a relative, friend or neighbour !?!!
Thank you sir
great video
Good... Can u post about cylinder liners, gaskets,
Thanks for information...
Your speaking fluent I like it
Nice thanks broo
In motorcycles, what would you consider a small engine? Like in cc or number of valves..
Is 175cc in motorcycle good for air cooled or it must be water cooled?
It is ok for a 175cc to have a water cooled engine, except for the +250
200cc usually use an oil cooler
Always better water cooled.
125-150 up should be liquid cooled
for a 190cc bs6 engine is aircool or liquidcool better or are they more or less same ?
Water cooling always better than air cooling as long as water temp 170 degrees no more.
Nice
Awesome 👍 highly appreciated
2:20 How big is big engines?
200cc and above
@@hexa38 i think you mean 2000 cc??
@@MrAmrmnabil no, 200cc. 200cc have liquid cooling
Super sir
Just asking..if ever in a critical area..it is possible to use ordinary water in our liquid cooled radiator???
I've done it in a car. The biggest problem is that water freezes. So you don't want it in your engine in cold weather.
If you must use water in freezing weather just make sure you drain it all out before you leave the engine. Then put it all back right before you start it.
Harley davidson superlow 883 cc is air cooled... is it a good thing or what...

So putting radiator to 150 cc bikes aren't necessary?
With a radiator the 150cc engine will perform much better.
Air cooled 💪

Liquid
Liquid esp for diesel!
Does water come out from liquid cool engine ? I have seen 10 -20 ml of water coming out from my bike..is it a normal thing ??
Is water coming from your exhaust?
@@TechTrixInfo yes
@@vit-c3300 you got some serious problems mate
You should be checking compression. If it's low it's very likely a blown head gasket. Caused by running high water temp and/or not changing oil.
Is liquid cooled efficient or more powerful than air cooled engines?
yes, is the answer
Liquid cool is better .. air cool is my 2nd choice .
Small bikes like 110cc below doenst need LC.
so a victa 2 stroke mower is air cooled.
👍👍👍👍
Can i just put water in the liquid cooled engine or do i need something special?
Thanks

How long an air cooled engine can run continuously?
Until you are out of fuel
Maybe 2 hrs
All depends how hot it is whether the vehicle is moving how good of oil is in it.

You still get air cooling on a water cooled motorcycle with the fins. So, you get the two going for you.
Also, oil is still going to be cooler on my motorcycle due to the two air/water combination.
Will a bigger radiator or doubling the hose lengths make any differsnce?
