well if a car has lot of power say 300bhp@6000rpm, then if you just press the gas pedal and turn the steering and keep it steady the car seems to drift, but it ain’t drifting its the cars engine specs and dynamics that makes it do such thing with ease …. always in front of noops you can become hero with such tactics, but in front of pros, you…[Read more]
hey i forgot to mention the term …. the first two sentences are regarding under steer !!!
thanks
under-steer occurs when a car steers less than the amount commanded by the driver….FWD cars generally understeer. while cornering, the front wheels are performing both the action of changing direction & moving the car forward… in short, it deals with sharpness of turns….
Body Roll means, the load transfer of a vehicle towards the outside…[Read more]
Understeer is a phenomenon in which the car at speed does not turn as much or as fast as you want it to and just runs wide. This is a characteristic of front wheel drive layout and can be considered as a built-in safety feature for the masses; it helps novices keep the car pointing straight. When you take turns at speed, you feel all the weight…[Read more]
refer to this link ….. http://www.cartoq.com/when-to-replace-your-clutch-plates-warning-signs/ …… i guess this should be more than enough for such ambiguities, which you’re facing …
Hold on. Don’t jump to conclusions. This recently happened with another person, where Toyota said the clutch had to be replaced, but all was fine. Go through the above link that Nikhil has posted, and also see this one: http://www.cartoq.com/%E2%80%9Chow-a-local-mechanic-saved-me-rs-25000-on-my-sedan%E2%80%99s-service%E2%80%9D/ I think you should…[Read more]
Injectors and throttle body need cleaning. As for shuddering, does the engine go kat-kat-Kat or does the vehicle start wobbling?
the first problem could be the speed actuator set to lower rpms …… with ac on the idle rpm level increases, i mean without ac if idle engine rpm rate is say 500 rpm, then with ac it becomes 700 rpm, thus with ac on try not to crawl below the latter rpm to avoid unavoidable stalls …. try this…… for shuddering issue, check your suspension…[Read more]
There should be no reason for the shuddering… I’ve taken the Wagon-R to three digit speeds without any hassles. The shuddering sounds most likely that you have a wheel balancing / alignment issue. Get it checked. As for the stalling, the rpm has been set too low – you’ll need to get that corrected.
No link. FE is affected by how long the compressor runs. Fan is simple battery operated
If AC is on & we kept fan speed very slow…then will it affect on milege ??
Low or high does not matter. Like I said, fan speed has nothing to do with the FE.
No, mileage is affected only by how long you keep the compressor on. Fan speed is purely electric – from the battery, while the AC compressor runs off engine power – and when the compressor is on there is load on the engine, which then consumes more fuel.
Experts, this has again created doubt in mind. A few days back i have asked similar question that does AC cooling (1-4) affected mileage. I know fan speed has no relation with fuel consumption it operate on battery, but if AC is on (i.e AC compressor on) & fan/AC is moving 1-4 modes does operating AC on 1 mode return better mileage than operating…[Read more]
hey @abhijeet, the blower is battery operated, so when you just using blowers and no ac (then no fuel consumption)….. but when you’re using blower cum ac, then at higher blower speeds, more pressure on compressor as more air to cool, so fuel economy decreases, (but remember, here the blower is not consuming fuel, its the more air which is forced…[Read more]
Rajvansh I guess your question was better way to express ..to the experts: that means if we switch the fan speed to 4 it would give better milege becoz the already temperature set will reach more quicker..!
hey rajvansh, the ac with blower speed set to 1, will definitely consume lower fuel, when compared to the ac blower combo at 4 …. guess i’m clear !!!
In case the car in parked under the sun, there are various ways to make it cool quicker than just running the AC on full blast. Remember, nobody runs the fan at max unless you have passengers sitting at the back; its just too noisy. Whats mentioned above regarding the pressure on the compressor because of the the fan speed is untrue. Compressor…[Read more]
@nikhil :: I really appreciate your ans sir..just last one thing..just few days back I was driving in mountains with ac on…while going to more steep area..when I use to slow slow down the blower speed it was easier for my car to move..than runing on high blower speed..
well shreyans sir, let me put here what i know ….. first the COMPRESSOR compresses the freon to high pressure, thus it becomes hot gas at high temperature, later CONDENSER, condenses this hot gas to hot liquid,at high pressure, later this hot liquid is expanded in EXPANSION VALVE, which gives a low pressure cold gas as output, which is sent to…[Read more]
NOW, an alternator is a load on crankshaft, and it consumes fuel indirectly for rotor rotation (in generating station you need steam turbines to drive rotor and here the engine’s crankshaft)…. and alternator functions properly upto lower rpms, at higher rpms it free wheels, with mere output, the alternator output does not increase if we rev up…[Read more]
grande punto is definitely sturdy and well built vehicle ….. except the ASS issues, none so far mentioned any downgraded points regarding this vehicle ,,,,, but in petrol variant, the grande punto 1.2l could be called as underpowered, when in comparision to other 1.2l hatches …. but 1.4 l is much better …. if you’re die hard punto fan wait…[Read more]
what about dyanamics and ride and handling
just awesome ….. if willing to buy, get the 90hp
We had reviewed the Punto last year, when it was launched. But I think it was the petrol one in the video: http://www.cartoq.com/new-fiat-punto-video-review/
