[xBhp Universal Thread]: Oil cooled vs Liquid cooled

So now ain't the P220/200's really Oil Cooled too and not just Oil 'is' cooled?

cooling maintaining temperature is for clutch friction, not for bike.

i guess liquid cool engine works almost the way shown on the 2 links below:
liquid takes excessive heat rather than lubrication.

Well the discussion is really interesting for lay man like me.
Its quite informative. Thanks for not closing this thread as one of senior member said. moving ahead what are dry and wet clutches what are there functionality and as someone said in motogp they use only Dry ones??

I too was on the 'other' side, till I had a debate with someone interesting!

Yes, Yes....I am not saying that Bajaj's Oil Cooled funda works as well as the LC engine. I am also not saying that the basic principle is the same.

The cooler running oil definitely means that the overall the engine would be running cooler. The crankcase is not separate from the cylinder block you know!

I agree...cooler running of the engine oil definitely means better engine performance. But the only difference is that in case of Liquid Cooled engines, the engine is cooled via jets of liquid (coolant) which keep circulating to maintain optimum temperature.
Whereas, in case of Oil Cooled as in Pulsars, the engine oil uses the surrounding air (air cooling system) to cool not just the engine, but the engine oil also!
Therefore, IMO liquid cooled engines will be less prone to overheating, but the engine oil wil stay better for oil cooled engines!

^^ You got me wrong dude.

I did not say that the Pulsar's oil cooling is as effective as a proper LC setup. All I am saying is that it definitely aids in running the engine at a slightly cooler temp. and thus the tag 'Oil Cooled' is not really a that wrong!

at the given price of the pulsars........
oil cooled works for me!!!!!!!!!!!

Oil cooling thing definitely works. Especially with the 300V... this is a cheeky solution that Bajaj had to pull out to make the extended Pulsar family work.


hmmm.... aren't we repeating the same stuff again

Ok, one basic question.

Which one of oil & liquid cooled is efficient and in what cases/scenarios?

Are there any scenarios where it doesn't matter whether the engine is oil cooled or liquid cooled?

Liquid cooled is more efficient in all scenario.

Regarding your second question. Let's put the question the other way round. Are there any scenarios where it DOES matter whether the engine is oil or liquid cooled? Yes. Chiefly, when engine is covered as in cars or fully faired motorcycles, liquid cooled is best.

Both Zmr and P220 resorted to cheaper solution to overcome heating problem. Well, both engines are not blowing up due to heat, so I guess one can say, it doesn't matter in this context.

As much as we the common users are concerned it really doesn't matter,its just about having a better technology in our bikes. Since our bikes are seldom put into really harsh riding environment repeatedly, like lets say a race track. Repeated testing or running of the bike in flat out red lining scenarios, that's where liquid cooling and air cooling/oil cooling difference comes into play.

And there is also an another factor that i feel, the cooler the engine is in whatever environment its better for the long life of the engine. So if i had a option to choose, i would take liquid cooling, for the technology,its effectiveness and long life of the engine.
