PD Simplified | Engine Cooling Systems 

Hey #PDArmy, we hope this helps you understand the difference between the cooling systems! If you wanna know more, do Comment below, and if you want to see more like this, give the video a Thumbs Up!

Shumi explains better than my professor, hands down!

As the syllabus mentioned in Applied Thermodynamics of Mechanical Engineering, TY students have this topic, great initiative by PD team, I always enjoy stuff explained by Schumi!

Which cooling system do PowerDrift use? Coz You guys are the coolest thing during the summers 😉

Pulsar 220 , first oil cooled machine for the masses. 70k kms , still going strong. Thanx PD for simply explaining the facts

My old ktm proves that any cooling system is not good enough for a ktm😆

Shumi, you are expert in explaining complicated things in a simple way. Great podcast series

Whoever came up with this idea needs a raise in this channel... this channel was all about just reviews with fancy cinematic and tough vocabulary... this is what we need... teach the youngsters about bikes in depth, it's technical knowledge, maintenance , repairs, working etc... This is great work guys... Kudos ❤❤❤💯💯💯💯

Well said "Look for the motorcycle which makes you happy, that's far more important than what cooling system it uses". 🤙❤

As an owner of CB350 RS, which employs an Air-cooled Engine, this video has put me at ease. Less things to be worried about. 😜 Thank you. Keep up the great work, Professor Shumi..

Shumi's detailed and in depth explanation automatically inspires to crush that like button!

Some rumours had recently stated about VVT (variable valve timing)technology that bajaj might be bring out along with new pulsar 250f , plz cover this topic in ur upcoming video.

If Shumi _sensei_ keeps up with such great explanations, pretty sure Byjus will want to acquire PD.

As an automobile engineering student ur videos are very useful to me

PowerDrift and Shumi have time and again proved to be the best place motorcycle and car lovers can come to, for nothing other than enlightenment! No nonsense content only for those who live and breathe automobiles! ❤️ I mean, you can find tons of videos in RU-vid where they rev bikes hard, reach the top speeds and top altitudes, but to give you the ecstacy obtained from simply knowing more about your machine; that's where these guys Excel. Keep up the good work, and please don't ever stop! PowerDrift is a family I really want to see grow! More power to you. 🔥❤️

Need a video on bike batteries, what wattage/voltage should we buy now as extended lockdowns and aho draining battery.And as most bikes are ditching kick starter, this has become a major problem.

Great concise knowledge I have subscribed to this channel since r15 2.0 review was out. I love this simplified series.

Thank you for the light of wisdom to dispel the darkness of motorcycling ignorance!!! Although I am Bajaj fanboy, choosing an NS200 over the Apache 200 because the latter does not have liquid cooling is ridiculous.

You are doing all of your viewers a massive disservice with this video. There is a substantial improvement in longevity of a liquid cooled engine against oil or air. Especially if used in hot and urban conditions.

I don't know if it's just my own experience, but air cooled engines tend to consume a little bit of oil on long rides, while liquid cooled bikes can run for thousands of kilometers without adding a drop of oil or coolant. I think it's because air cooled engines have larger tolerances to allow for heat expansion, while liquid cooled have a narrower temperature range and therefore tighter tolerances.

Loved the conclusion that shumi explained “buy the motorcycle that makes u happy”

His explaination always feels personal !

I wait all day to watch Powerdrift Vids!!! Why are they sooo good? Also Love Shumi!

Thanks for the crystal clear explanation. Absolute clarity. Thank you bro.

I knew this, but saw the full video as I love the way you speak 👌your enthusiasm is amazing

This simplified series is a boon for all automotive enthusiasts and Shumi is the best man for the job !!!

SIR WONDERFUL ELOQUENCE AND BEAUTIFUL EXPLANATION..LOVE YOU AND YOUR WISDOM THANK YOU

Yes we want the video on how the liquid cooling system works on bikes in detail. Thank you for the wonderful information❣️👏

Hi Shumi please come with series of video on EV Policy and also regular changes on that as it's complicated and changing within a short span

Extremely well explained, thank you!

The elegance with which shumi speaks is just awesome

The best cooling system to get over this boring lockdown time is "power drift " cooling system 😜🙏

Shumi should open a school of motorcycles.... Hands down, he is the best teacher

This really made a world of difference, helps understand things a lot better !

Excellent, simple, concise...great job!

that's a simple, precise explanation which is very informative.... well done👌👌👌

PD simplified is way informative! Loved it!

Thank you so much Sir for very simple way of explanation.

Thank you Shumi.. And PD.. Love ur podcast.. ❤

It's indeed wonderful to understand complicated content in byte sized pieces. I would love to know more about 2 valve and 4 valve engines. What impact does it have on performance and efficiency?

Really wishing for a simplified version of all the types of Braking systems used on 2-wheelers....like drum, discs and then comes the double discs or single discs and all...

would love a discussion on short gearing and long gearing and effectiveness of both

From My Experience, I can say that If You Buy a BUDGET Bike Below 500 cc Oil Cooling is the Best Option to Go If an Air-cooled Engine can do 600+kms Nonstop On a Day without any problems, there is no Point spending the Extra Cash for a Liquid Cooled Engine.....But More than 500+cc Liquid Cooling is a Must

Learnt something new today. Thank you shumi

Awesome video Professor ❤️

Yes Shumi.. plz make videos on how the colling systems really work.

My kind of Morning News.. Thanks a lot Shumi Sir ❣

As always you guys never i repeat never leave a chance to impress your audience with knowledge and information of automotive world by just simplifying it. ❤

Powerdtift my favourite car and bike reviewer ❤️❤️ I always wait when powerdrifts videos will come ❤️ Btw shumi reaaly a great explanation

Would like to know about the advantages and disadvantages of both led and halogen during rain,fog and night

Thanks guys the video was very informative. It helped to Understand about cooling system very quickly in a easy and short time. ❤❤keep doing this kind contents more. Wait for the next episode of the signals to signals.

Very well explained!! Keep up the good work!

From Karnataka 🙏 sir iam always watching your vedio and it's..... amazing and with helpful content 😊

Well explained

Good Morning Teacher (Shumi) 😜 Excellent Video to understand the basis.

wow i always thaught Air cooled is big con but now my concept get cleared.

Really good info thanks pdarmy

Well explained sir thank u regards

How to choose riding gear? A video on that will save lives 🙏🏻

Can you guys make a video about the different types on engines and how they work? Thanks

Hey guys! Could you do a video on the breaking-in of an engine, and why we should do it? Thanks!

Thanks shumi

Thank you sir

Hi Shumi ! thank you for explaining it in so much detail and really simplified way . Just had one doubt if engine cooling system matters for riding bikes at very low temp region for eg at ladakh ?

Harley Davidson has Air Engine cooling problem. I am a Harley rider and have seen 2016 2017 Fatboy models stop due to engine heating in slow Mumbai traffic (not in summer but also in Oct Nov). When this happens we used to wait for 20 25 mins and then the bike starts again.

I can listen to Shumi all day ❤

Yes, would like to know In detail.

Just liked the way how he summed up everything a to make the most important point at the end.

How tyer engineering works on bike should we change the tyer size from stock or not or only choose recommended tyers from motorcycle company??plz reply

Sir, pl do a video on Booster Plugs in superbikes & how effective is in yerms of rideability?

Yes i agree. Follow your heart and get the bike that satisfy you and trust the engineers who designed your engine to get the appropriate cooling system.

PD bhaiya ye batao. Should I buy cb shine if i have back issues in past or should I buy a platina? Which commuter has good comfort ride? Or Tvs raider. Which one should I go for?

Thanks shumi.

Superb sir

100%agreed 👍

Cooling system is most important to run an heavy engine , Nice explanation 👍😊

Love you Shumi

Hey Shumi, please do a simplified video about rear suspension PreLoad adjustability for different riding scenarios. Please don't UN-Simplify it by going into Compression and Rebound adjustability.

I beg to differ, i used to own pulsar 150 (2010 batch), when riding enthusiastically on long distances and especially in hilly terrains, it shuts off due to certain heat of the engine. I had to stop often, say after every 40km or so. Second, I currently use NS200 bs6 as my commuter, as it's a liquid cooled, the hot air gets directed to the lower parts of the legs but by the time it touchthe legs, it feels warm (not hot). Travel 100km in a single take, it doesn't dissapoint.

Really simplified ❤️great 👍

Some information regarding ENGINE OIL ADDITIVE are they any good?

This is what i want to study mechanical engineering....

Hey try to do a video on slipper clutch, dct clutch ect

excellent this is really simplified..

Hi Prof! Brilliant video!

Water, air and oil cooled engines are in the end air cooled engines. The difference is in what type of liquid/gas we will use to dissipate/transfer heat from the source. I have a BMW motorcycle with a boxer engine. The engine is cooled by air and oil, plus there are no problems with traffic jams because it is equipped with a thermostat and a fan. I don't see any flaws. Water cooling is "future" bc the reduction in oil capacity and emmisons standards is intended to preserve the environment. So today, highly efficient engines are made that are more enviromentaly friendly, and on the other hand, there are more complex systems that require more expensive production and maintenance, as well as a higher probability that something breaks down.

Look for a motorcycle that makes u happy. This line has my heart ❤️ attached to it

Thank you Shumi, for busting myths.

I did observe that higher the compression more sophisticated is cooling system required. For eg, gixxer sf250 vs fz25 vs R15.. r15 being highest has LC system whereas sf goes with OC system and fz just gets with air cooled. The relation mostly i see is with compression ratio. Please correct me if I am wrong.

exactly

Almost in every video, Shumi is saying to buy the bike you love the most. That is the most important advice.

pure wisdom

Sir I want know about both cooling system like ducati v4r pumping mechanism and pressure oil pumps mechanism like superduke

What is important is the engine oil temperature as viscosity of the lube oil varies with the temperature. Any cooling system needs to keep the lube oil temperature within specified range to prevent its faster degradation and viscosity within range for low frictional HP loss. It will be worth to compare the lube oil temp of two 250 CC engines (each having different cooling systems) after say a 100 km run or steep climb of 30 - 40 km ie something similar to the dyno tests being done by auto journalists.

Pls do a detailed video on how liquid cooling systems work...

Professor Shumi 🔥🙏🤴

Cooling system is decided by manufacturer based on compression ratio of air fuel mixture. High compression(above 10 :1) engines like ktm have liquid cooled engine, low compression engines like harley and royal enfeild interceptor have air cooled and some bikes use oil cooler. And gixxer 250 cooling system does not fit into any of 3 cooling system explained by shumi. Its fully oil cooled without engine fins

Shumi sir the Best. ❤️

bhaiya shoub be my subject teacher😅. the way he explain is just amazing.

I feel Air cooled are the best for Indian conditions.... unless you hit tracks or do serious highway cruising!! 👐
