What is Turbocharger And How it Works?

What is a Turbocharger?

Have you ever watched cars buzzing past you with sooty fumes streaming from their tailpipe? It’s obvious exhaust fumes cause air pollution, but it’s much less apparent that they’re wasting energy at the same time.

The turbocharger

The exhaust is a mixture of hot gases pumping out at speed and all the energy it contains—the heat and the motion (kinetic energy)—is disappearing uselessly into the atmosphere. Wouldn’t it be neat if the engine could harness that waste power somehow to make the car go faster? That’s exactly what a turbocharger does.

Car engines make power by burning fuel in sturdy metal cans called cylinders. Air enters each cylinder, mixes with fuel, and burns to make a small explosion that drives a piston out, turning the shafts and gears that spin the car’s wheels. When the piston pushes back in, it pumps the waste air and fuel mixture out of the cylinder as exhaust. The amount of power a car can produce is directly related to how fast it burns fuel. The more cylinders you have and the bigger they are, the more fuel the car can burn each second and (theoretically at least) the faster it can go.

One way to make a car go faster is to add more cylinders. That’s why super-fast sports cars typically have eight and twelve cylinders instead of the four or six cylinders in a conventional family car. Another option is to use a turbocharger, which forces more air into the cylinders each second so they can burn fuel at a faster rate. A turbocharger is a simple, relatively cheap, extra bit of kit that can get more power from the same engine!

How does a Turbocharger Work?

If you know how a jet engine works, you’re halfway to understanding a car’s turbocharger. A jet engine sucks in cold air at the front, squeezes it into a chamber where it burns with fuel, and then blasts hot air out of the back. As the hot air leaves, it roars past a turbine (a bit like a very compact metal windmill) that drives the compressor (air pump) at the front of the engine.

How turbocharger works

This is the bit that pushes the air into the engine to make the fuel burn properly. The turbocharger on a car applies a very similar principle to a piston engine. It uses the exhaust gas to drive a turbine. This spins an air compressor that pushes extra air (and oxygen) into the cylinders, allowing them to burn more fuel each second. That’s why a turbocharged car can produce more power (which is another way of saying “more energy per second”).

A supercharger (or “mechanically driven supercharger” to give it its full name) is very similar to a turbocharger, but instead of being driven by exhaust gases using a turbine, it’s powered from the car’s spinning crankshaft. That’s usually a disadvantage: where a turbocharger is powered by waste energy in the exhaust, a supercharger actually steals energy from the car’s own power source (the crankshaft), which is generally unhelpful.

How does turbocharging work in practice? A turbocharger is effectively two little air fans (also called impellers or gas pumps) sitting on the same metal shaft so that both spin around together. One of these fans, called the turbine, sits in the exhaust stream from the cylinders.

As the cylinders blow hot gas past the fan blades, they rotate and the shaft they’re connected to (technically called the center hub rotating assembly or CHRA) rotates as well. The second fan is called the compressor and, since it’s sitting on the same shaft as the turbine, it spins too. It’s mounted inside the car’s air intake so, as it spins, it draws air into the car and forces it into the cylinders.

Now there’s a slight problem here. If you compress a gas, you make it hotter (that’s why a bicycle pump warms up when you start inflating your tires). Hotter air is less dense (that’s why warm air rises over radiators) and less effective at helping fuel to burn, so it would be much better if the air coming from the compressor were cooled before it entered the cylinders.

To cool it down, the output from the compressor passes over a heat exchanger that removes the extra heat and channels it elsewhere.

Diesel Car Fuel Economy

How To Improve Diesel Car Fuel Economy

The car market in India has been termed as novel by specialists the world over. Take fuel decisions for occurrence. Indians have long demonstrated a solid fondness towards diesel controlled cars, because of the steady fuel-evaluating approaches too. Additionally, with developing mechanical headways in motor development, diesels have turned into significantly more fuel proficient than some time recently. However, separating the most out of things comes simple to us and along these lines, here are a couple tips to drive the diesel car monetarily.

Cut the hostility: While pertinent to petrol cars as well, maintaining a strategic distance from forceful driving propensities is one of the top diesel cars driving tips. This exclusive winds up blazing overabundance fuel, without adding much to the rate or the time funds. Quiet and smooth is the approach here.

Comprehend the motor attributes: A diesel motor creates power, let down the rev range and regularly have a low top-rev restrict as well. In any case, they do have one secret weapon and that is the torque. Limit for limit, a diesel motor will be more torquier than its petrol partner. So comprehend the motor attributes.

Know your torque: So now that you realize that a diesel motor puts out more torque, you must ace the specialty of riding along it. Staying in the right rigging which places you in the meat of the torque bend is a standout amongst the most vital diesel cars driving tips to expand driving delight, also the higher fuel normal you’d be getting.

Get the rigging moves right: Unlike a petrol car that can clutch higher revs, a diesel will rapidly come up short on steam. The key then is to move up at the perfect time. Late rigging movements will basically smolder more fuel, while too soon an apparatus shift and you’ll end up carrying the motor, sitting tight for it to come into the powerband.

Utilize the turbo: The critical dominant part of diesel motors today are of the turbocharged sort and one of the tips to drive the diesel car monetarily is to figure out how to utilize the turbo, to concentrate better execution and thusly, better mileage.

Driving a diesel car isn’t as troublesome as it once used to be. Besides, progressions in innovation, they have contracted down the hole as far as refinement and upkeep required.

Petrol-VS-Diesel Cars In India

Petrol vs Diesel Engine Car – Which Should You Choose?

Often the first time car buyers, who don’t have any idea about the cost and maintenance required with a four-wheeler, are stuck in the issue of Petrol vs Diesel Car. Such people are very particular about the returns in the form of a better fuel economy and the prevailing prices of diesel and petrol in the market keeps bothering them. After all, owning a car is not that simple as it seems to be. It’s not just about the looks, features and shades, but the mechanical configuration is something which takes time to be studied.

Although, there are plethora of options available today including petrol, diesel, plug-in hybrids and electric powertrain, but the main dilemma definitely prevails in choosing either a petrol or a diesel car. Some might think that a petrol car would be good, while some may prefer the diesel variant. This is a never ending topic which involves a lot of factors to be considered, before any conclusion is drawn.

Since we realise the value of your hard earned money and are concerned about the returns that you get, here’s a brief analysis about the topic- Petrol vs Diesel car so that you might get an idea about making a wiser decision after going through all the pros and cons. So, let’s get started! Wink!

Should I buy a Petrol or Diesel Car?

If you ask anyone whether buying a petrol car would be feasible or a diesel car would be more profitable, you won’t get a definite one word answer. This is because before making any decision, one needs to closely study all the aspects of both the powertrains and thereby come to a final verdict.

Petrol-Engine-VS-Diesel-Engine Cars in India

So, let’s take a look at the factors that altogether help in determining as to which option should be chosen:

Price Gap:

Usually, almost all the brands sell their models in both petrol and diesel versions and the former are always cheaper than the latter ones. So, if you wish to cut down the cost a little bit then buying a petrol car could help you save some bucks. For example: If you wish to own a Maruti Suzuki Swift, the ZXI (Petrol) is available at INR 6.4 Lacs, while the ZDI (Diesel) is tagged at INR 7.4 Lacs. So, we see that there is a gap of INR 1 Lakh between the two. And when you’ll compare the on-road prices of these variant, the difference could be around INR 1.28 Lacs.


The rate at which you use your car, largely determines whether you should choose a petrol car or a diesel one. The more you travel, the more fuel you will need and hence mileage plays a big role over here. If your cars covers on an average 1200-1500 km in a month, then you should straight away choose diesel engine.

Those residing in metro cities like Mumbai or Delhi have to travel a lot and hence for them diesel would definitely be a suitable option. On the other hand, if you seldom drive around, or use your four wheeler for short distances, then you can settle with a petrol engine.

Fuel Rate:

Even though diesel cars are pricier than petrol ones, but when you get to the petrol pump to get your tank full, you’ll end up paying more for petrol. This is because a lot of factors are responsible in fixing the fuel prices, which may differ from one state to another. However, due to the deregulation of diesel prices by the Indian government, the gap between the prices is shrinking day by day. As of March 1, 2016 the fuel prices in New Delhi stand at INR 46.43/Ltr (Diesel) and INR 56.61/Ltr (Petrol).

Miscellaneous Expenses:

When we own a 4-wheeler, it’s not just the on-road price that has to be paid, but several other costs are also involved in maintaining the vehicle. The car needs regular servicing and needs to be repaired in case of a defective part. Since no spark plugs are used in a diesel car, that cost can be surely eliminated. But, at the same time they need investments regarding turbochargers, oil replacement, battery and clutch plate.

Nissan GT-R 2016

5 Things You Need to Know About the New Nissan GT-R

New Design

Nissan lets us know the extent of the front opening was expanded by twenty for every penny, taking into account better cooling for the radiator, as well as the oil cooler as well. The sash, likewise new, oversees wind stream around the wheels too.

However, it’s not about numbers, as Nissan – properly – says “you don’t drive in a wind burrow, you drive in this present reality where wind is originating from all over, and a great deal of the unpretentious changes we’ve done help us deal with that wind stream in certifiable circumstances and genuine vehicle mentalities, not only a lab condition”.

Likewise, any other individual supposes it looks more like the first GT-R idea car than at any other time? Nissan concurs, however not simply on a restorative level. “These things are all intentional. They’re not all restorative. We just rolled out the improvement where it enhanced the capacity.”

Enhanced Engine Power

20bhp more, to be exact. Nissan used tech from different cars, conveying singular barrel ignition control, with a specific end goal to streamline the ignition fire significantly more remote than some time recently.

This permitted the designers to change the help weight, keeping in mind the end goal to concentrate more torque over a more extensive territory. “You can truly see it in passing circumstances,” we’re told. “It’s truly a passing car. This vehicle never had an issue with force. We gave it a tiny bit more. There’s presently energy to save.”

There’s a torque increment over the reach too, while that ignition framework utilizes tech carried over from the Nismo form. Feature details? 562bhp at 6,800 rpm, and 469lb ft of torque. Furthermore, a 0-62mph time of 2.8s. Still mercilessly, ruthlessly snappy, then.

New wheels and Tyres

Nissan says the new GT-R’s more unbending body structure and new suspension, partnered with new tires and 20in, 15-talked produced aluminum wheels grasp, which thusly gives is said to give better steadiness through “brisk parallel moves and higher general cornering speed”. Better believe it, in light of the fact that the old one was such a sluggard…

New Improved Interior

This is the huge one for the new GT-R. As specified, Nissan needed to concentrate on the “GT” viewpoint – and overhaul what was, basically, a seven-year old inside. “We needed to enhance the usefulness,” Nissan clarifies. “Truly, the greater part of the progressions that we’ve received for this vehicle have a useful explanation behind why they were embraced.”

So the quantity of switches on the middle console were diminished from 27 down to only 11. “We need you to keep your hands on the wheel progressively and appreciate the driving, not look for something.” The oar shifters for the gearbox were moved onto the wheel rather than the segment – so they move with you – while the seats were dealt with to a smidgen all the more supporting and solace. We’ve sat in them, and can bear witness to their, um, bolstery-ness.

At that point comes stuff like a lessening in commotion, vibration and cruelty on account of new auxiliary components, and an acoustic windscreen.

This is a Mix of Old and New Model

At the point when addressing Shiro Nakamura, Nissan’s Senior Vice President, Chief Creative Officer and the man behind the GT-R’s configuration, he said the most recent cycle is the happiest he’s been with the R35’s outline.

“I was given the most flexibility I’ve had in seven years,” Shiro said. “The front end has a much more grounded character, and do you recall the Vision 2020? Indeed, I attempted to unite components of that with the first 2001 GT-R Prototype.”

hot hatchbacks in india

Why Should You Buy Hatchback Over A Sedan?

Execution – it’s something we search for in each part of life, whether it’s execution to convey those month to month targets or execution by the pizza conveyance man to get you that request in under 30 minutes.

Car patterns have traveled every which way, however here we are more than 3 decades later and this sort of car is still as mainstream today as it was in those days, if not more.

So why would that be?

How is the basic recipe of adding more energy to a normal little car so successful? Indeed, here’re 5 reasons that make hot hatchbacks so alluring:


Hot hatchbacks sufficiently offer execution to get a grin all over, however despite everything they make incredible regular cars. So when you’re not hoping to take a couple of hard corners on that weekend excursion to an adjacent slope station or blaze through a couple tires on a track-day, you can at present drive it to the area market and have enough space in the boot for gear. There are additionally enough seats to take the family around once a day, so it’s one car that deals with various parts.


Execution cars, sports cars and supercars demonstrate no leniency to your wallet. They’re huge in size, need greater motors and accompany enormous sticker prices as well.

For somewhat more eliteness, VW will likewise dispatch the Polo GTi that will set you back by around Rs 20 lakh. That is a major sum, yet what you get is a street burning force yield of more than 190PS that gives it a 0-100 kmph time of 6.7 seconds. That is faster than the BMW 320i which costs twice as much.

Usable Performance

Think about the Audi R8, Lamborghini Aventador, Pagani Huayra, Ferrari 488 GTB or Porsche 911 and all that strikes a chord is their stunning yield figures and top rates. Be that as it may, while every one of these cars cost as much as a rich home, you once in a while get the chance to utilize even 10 for each penny of their potential. Speed limits, tight streets and movement guarantee that you generally need to hold off the throttle, unless you’re in a protected domain like a race track, where pushing your supercar as far as possible is lawful.

A hot hatchback, then again, offers only the appropriate measure of execution. You can squash the throttle to make an overwhelm in a split second and even beginner drivers can oversee what execution the car brings to the table. Indeed, even on the open expressway a hot hatchback will excite you with how well it can oversee high speeds, deserting greater cars far.

Compact Size

A little impression makes hot hatchbacks simple and exact to handle. The little wheelbase combined with an exact guiding makes a hot bring forth simple to flick into corners and controlling one isn’t a modest bunch. In urban conditions, dashing through activity or stopping in a tight spot is no bother either.


It’s generally great to have a car that is fit for brain boggling execution that doesn’t shout about its capacities constantly. In truth, some execution hatches do get noisy stickers and wild paint occupations, however a hefty portion of them have unpretentious augmentations (changed guards and front grilles, distinctive wheels, spoilers and so on) that lone a sharp eye can spot.

Keeping up a position of safety is cool and such cars are for the tasteful driver who drives a quick car for the delight of driving and not to ask for consideration. Also, dons cars tend to welcome a great deal of desirous blackguards. A hot trapdoor can stow away on display, keeping it sheltered and sound.
