2009 Bajaj Pulsar 220 Discussion Thread - First Ride Impression at Post No. 514

Bajaj forgot to mention the word "is" between "Oil" and "cooled", actually!

Quote from Wiki

Some manufacturers use a hybrid cooling method where engine oil is circulated between the engine case and a small radiator. Here the oil doubles as cooling liquid, prompting the name "oil-cooling." Suzuki has produced many "oil-cooled" motorcycles.

In which case , we can still call the Bajaj motorcycles as Oil Cooled and need not necessarily be called "Oil is Cooled".

The basic design is an air cooled engine, with an aided benefit of the oil cooling the internal components.

I guess such oil cooled engines will have a fan to cool the oil when idling but yeah this will help the engine oil run cooler on long drives improving the life of the engine parts.

I'm not sure about the fan part, but the point is that there are big manufacturers who very much use the engine oil to cool their engines and call them "Oil Cooled". So I guess no big deal in calling the Bajaj bikes Oil Cooled either as opposed to Oil-is-Cooled. The point that these engines are basically Air Cooled engines is a different point altogether.

EDIT: I realize a difference though. The oil in the Suzuki engines at least circulate over the engine case, whereas in the Pulsars all it does is come out through the radiator and go back in, hence helping the internal components stay cooler.

Dude, complete the run in , then start ripping, it has only been 800 kms. personally IMO,it is still the best pulsar over all, roll on is slower than the DTSfi but not the 180.

i guess you are right.
otherwise the bike looks and feels great.
this is my 3'rd pulsar and i know that the performance gets better and better with time. i remember feeling the same way initially when i traded in my 180 classic for the 180 dtsi v1.
only other problem is with the front disc hose rubbing against the oil cooler shroud. already the plastic covering is getting abraded.
any solutions? i have put duct tape on both surfaces.

Cancelled my 220 booking yesterday as the delivery would take another months time they (PBK) said. Will prolly go for the RTR 180.

ok here is the deal, Engine colling is different and oil cooling is different. Engine cooling has two types: Air cooled and radiator cooled

Air Cooled: Engine gets cool when the atmospheric air passes through the fins of the engine and cools it down, effective for small capacity low power engine.

Radiator cooled: This is further devided in to two types. one is liquid cooled which uses coolant and the other is is water cooled which uses water. The radiator fluid or water goes through the engine through plumbing like pathways designed inside the engine creating a jacket of water or coolant which cools down the engine then the water or the coolant itself gets cool by being chanelled through the heat exchanger.

Oil cooler: This has nothing to do with cooling the engine directly. The engine oil is chanelled through the cooler which keeps cooling the engine oil while the bike is running , thus increasing the heat up time of the engine.

Take it to Bajaj and ask them, If that doesn't work lodge a complaint with customer care, they will figure out a way.

Not really. If you look up in history many Fiat and VW cars have air cooled engine in fact most of the Aircarfts(pumping more than 300 horses) of that time too had air cooled engine(as a matter of fact all jet engines are air cooled) so its not for small engines as such. They are just two different cooling technologies, have their own pros and cons. Liquid cooling has become the mordern era cooling technique, may be because of its noise reduction capabilities.

In liquid cooling, the liquid is just a medium to carry heat, it can be any liquid. Its mostly a coolant(mixture of water and some silicone compounds) but it can be any thing else. Most old busses and cars use water. In the same fashion, oil too can be used to cool the engine. Its very useful in small engines and also in dry sump engines as it saves weight in storing another 2-3 litres of liqud and oil has a capacity to reach the inner most parts of the engine as opposed to any other liquid cooling systems allowing it to cool some cooling parts virtually not possible by any other liquid medium. Also a cool oil means more controlled viscosity and better lubircation. But like all liquid cooling, in oil cooling, oil has to sit in the jacket surrounding the engine and there will be an fan to keep the heat pumped into the air passing through the radiator, which is not true for the current Bajaj bikes. In fact the Bajaj oil cooler does not have fins to improve cooling efficiency on low volume air flow. I dont know if its even copper tubes.

All i can say is that the Bajaj Oil cooling will keep the oil in higher viscosity as it will be cooler(may be a deg or 2) compared to oils in other bikes. This will mean better lubrication == less friction == cooler engine components(like the bearings and bushes inside the piston and crakshafts) == longer living components. Traditionally cars have oil sump at the bottom (and it will be flat and many times in Aluminium with copper inserts) to help the cooling of the oil as the bushes and bearings in crankshaft can heat up significantly when running fast for long or even when you have lots of hard accelerations, they also decide on the amount of oil based on how quickly the oil can be cooled. Many big bikes to carry fins on the oil sump to help cooling the oil.

Basically it will help if you are highway riding fast for long, it will not help if you are driving is city(or below say 40 kmph) for too long. You could add a fan behind the cooler though to make things better in city, just a Rs.300-400 project. If you are more interested you could add fins, a thermostat control for the fan too and some plastic ducts to direct the air away from the engine.

^^I am seeing this type of post after a long time..Typical arunmur post. I dont have to share much over here but will gain the knowledge of information!!

Holy moly: I was only talking about the Indian scenario dude.
Thank you for clarifying.

OT...

1. Naturally....Engine makes the oil to behave 'dynamically'....I mean at low speed/low temp the viscosity will be high (thicker) and high speed/high temp. the engine heat tends to make the oil less vicous (thinner). So one type of oil viscosity is not suitable for engine operation over different conditions, oil has to behave dynamically.

2. On the contrary if you 'imagine' high viscosity at high speed/temp ... this means high friction tendered by thicker oil, engine heats up,.......similarly if you 'imagine' low viscous oil at low speed/low temp....the lube effect will be low and friction increases (chances of metal to metal rubbing become more).

My points neither supports nor dismisses Oil cooler, but employing of oil cooler should satisfies basic objectives (point-1) with detailed study and validation.

[coolpepe]

Asked the dealer in Mandi (H.P.) and the dealer quoted the price of 71800 for the bike. Rest we have to get it insured and registered ourselves in H.P. So it will be ard 77k on road here. And the dealer told the waitin period is ard 15 days.

Edit: I asked the price for one of my friend who is goin to buy this bike in Black colour.

On all the talk on Oil Cooler, I woulke to point that Bajaj "oil cooling" technology, does little to cool the engine as such, In a liquid cooled engines, a Radiator can keep engine cool even at standstill. But yes with COOlER OIL, oil drain intervals should be longer, at the same time maintaing viscocity.
Even at higher speeds, the viscocity has to be maintained. The oil behaves dynamically under varying tempreature, it should not drop below a certain level.

Just called the Kiviraj motors. They are still claiming that the RTO approval is not over and it will need another 10 days. On further poking as to when the approval is expected to happen. He told deliveries expected to start on Monday. I told him that the better have an explanation for me on Monday if the RTO approval has not happened by then.

I think these guys are taking this too lightly and worst they even keep taking bookings and even full payments without having an RTO approval. This is total nonsense. I feel something should be done, but dont know what.

Oh Thats sad!! I can't get why Maharashtra alone got this RTO problem even when the bike is manufactured there..

Anyways RTR180 also being a nice bike you can be happy with your buy
