2014 Volkswagen Polo 1.5 diesel review

Volkswagen has substantially updated and reconfigured its Polo hatchback for India. Whereas the earlier car promised a lot but was hobbled by a weak and noisy 1.2-litre three-cylinder diesel engine and little equipment, this new car gets an all-new 1.5 diesel unit and more kit.
What’s new?
Volkswagen has made only small changes to the exterior of the Polo, which are so subtle that it's easy to miss them. Yet, these small tweaks are a step in the right direction. The bars of chrome in the chin and in the grille are well executed, the detailing in the headlights is quite classy and there are some new alloys too. Walk around to the back of the car and the details are even more difficult to spot. The tail-lights are new and the bumper has been re-designed to look a bit fuller. However, these changes are only visible when you take a closer look.
The biggest change VW has made is under the hood. It has downsized its 1600cc TDI or diesel engine to under 1498cc to help this version of the Polo get an excise cut, and the resulting reduction in price should prove to be really popular.
Indian customers never really took to the earlier non-linear, three-cylinder diesel, but this one is a very different kettle of fish. It’s really smooth when you start it up, the gravelly note of the earlier engine gone, the engine pulls cleanly from 1200rpm and torque flows smoothly all the way up to 4000rpm. You can spin the engine faster, to 5000rpm, too, but power begins to tail off. The motor takes its time to respond, but what’s nice is that there is no steep step up in power anywhere in the powerband, just a strong surge. The clutch isn’t the lightest around either, but VW’s slick gearbox makes changing gears a treat too; so, in traffic, the new VW Polo does quite well.   
This new 89bhp engine, however, does its best work once the roads open up. Acceleration is strong and the Polo gathers pace rapidly when the engine is kept spinning in its midrange. The 0-100kph sprint takes 13.08 seconds, although admittedly tested in slightly wet conditions, and this means overtaking slower cars is effortless.
The new VW Polo also gets an altered suspension. There’s a bit more weight in the steering wheel and the suspension now is much better at tackling poor roads. There’s more than enough compliance at low speeds and the suspension doesn’t crash through potholes like the earlier one did. The set-up, in fact, is very similar to the earlier Polo 1.6 TDI, but that also means it feels a bit ‘loose’ at higher speeds in a straight line and a bit skittish when cornered hard as well. VW has also improved the brakes. You now need to exert less effort when you want to stop quickly, which does give you a bit more confidence.
First verdict
More attractive, nicer to drive and better looking on the inside too, VW has upped the new Polo’s game substantially. With prices for the 1.2 petrol ranging from Rs 4.99 - 6.07 lakh and the new 1.5 diesel available for Rs 6.27 - 7.37 lakh, the new VW Polo is well and truly back in the game (all prices, ex-showroom, Delhi).

engine problems

nothing is perfect in this world 
neither you nor me and not even the machines we encounter in our day to day life 
for example the car engine 
now suppose one day you wake up late getting late for your work and when you try to start your car 
you are like "oh my god " not again why this car engine doesnt work properly 
now what comes first in your mind  What could be wrong?
 Now that you know how an engine works(plz see the previous blog for more details ), you can understand  basic things that can keep an engine from running. 
Three fundamental problems that might be spoiling your day 
  1. : a bad fuel mix,
  2.  lack of compression
  3.  lack of spark. 
Beyond that, thousands of minor things can create problems, but these are the "big three." Based on the simple engine we have been discussing, here is a quick rundown on how these problems affect your engine:
  • Bad fuel mix - A bad fuel mix can occur in several ways:

-if your gas tank is empty 
-clogged air intake  so there is fuel but not enough air.
-problems in fuel system like it is providing much or lesser fuel , meaning that combustion does not occur properly.
-impure fuel (like water in your gas tank) that makes the fuel not burn.
  • Lack of compression - If the charge of air and fuel cannot be compressed properly, the combustion process will not work like it should. Lack of compression might occur for these reasons:

-problem with piston rings like your cars  piston rings are worn (allowing air/fuel to leak past the piston during compression).
-The intake or exhaust valves are not sealing properly, again allowing a leak during compression.
-There is a hole in the cylinder.
-The most common "hole" in a cylinder occurs where the top of the cylinder (holding the valves and spark plug and also known as the cylinder head) attaches to the cylinder itself. Generally, the cylinder and the cylinder head bolt together with a thin gasket pressed between them to ensure a good seal. If the gasket breaks down, small holes develop between the cylinder and the cylinder head, and these holes cause leaks.
  • Lack of spark - The spark might be nonexistent or weak for a number of reasons:

-If your spark plug or the wire leading to it is worn out, the spark will be weak.
-If the wire is cut or missing, or if the system that sends a spark down the wire is not working properly, there will be no spark.
-If the spark occurs either too early or too late in the cycle (i.e. if the ignition timing is off), the fuel will not ignite at the right time, and this can cause all sorts of problems.
  • Many other things can go wrong. For example:

-If the battery is dead, you cannot turn over the engine to start it.
-If the bearings that allow the crankshaft to turn freely are worn out, the crankshaft cannot turn so the engine cannot run.
-If the valves do not open and close at the right time or at all, air cannot get in and exhaust cannot get out, so the engine cannot run.
-If someone sticks a potato up your tailpipe, exhaust cannot exit the cylinder so the engine will not run.
-If you run out of oil, the piston cannot move up and down freely in the cylinder, and the engine will seize.

basic engine parts

.Basic Engine Parts


The first  basic part of an engine is the cylinder 
why so ??
to understand that we need to analyze what actually a cylinder looks from inside 
here in the picture you can see what actually a cylinder looks like 
   the cylinder has pistons which moves up and down and is the core of the cylinder 
. The engine shown here  has one cylinder. That is typical of most lawn mowers, but most cars have more than one cylinder (four, six and eight cylinders are common). 
IN MULTI CYLINDER engine the engines are basically of three parts  : inline, V or flat (also known as horizontally opposed or boxer),

as every machine requires different configuration in engines also different configuration comes out diffrent results such as more smoothness 

now moving o to some other   key engine parts in more detail.
Spark plug

Spark plug
The spark plug is the device used to provide enough spark to the mixture of gas-air to have a combustion

Piston rings  (Photo credit: Wikipedia)
The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Note that both valves are closed during compression and combustion so that the combustion chamber is sealed.
Français : Piston
 Piston (Photo credit: Wikipedia)
Piston
A piston is a cylindrical piece of metal that moves up and down inside the cylinder.
Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. 
now many of you must be in deep thoughts that what actually is the role of piston rings 

  • They prevent the fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion.
  • They keep oil in the sump from leaking into the combustion area, where it would be burned and lost.
  • Most cars that "burn oil" and have to have a quart added every 1,000 miles are burning it because the engine is old and the rings no longer seal things properly.

The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates.
Crankshaft
The crankshaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does.
Sump
The sump surrounds the crankshaft. It contains some amount of oil, which collects in the bottom of the sump (the oil pan).



in the next blog we will be focussing on the basic problems we encounter in day to day life

what is otto cycle ??

  
nikolus otto

The four-stroke approach is also known as the Otto cycle, in honor of Nikolaus Otto, who invented it in 1867. 


 the four stroke are 
  • Intake stroke
  • Compression stroke
  • Combustion stroke
  • Exhaust stroke


 The piston is connected to the crankshaft by a connecting rod. As the crankshaft revolves, it has the effect of "resetting the piston"

what is intake stroke ????
The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke.

plz note:- Only the tiniest drop of gasoline needs to be mixed into the air for this to work. 

what is compression stroke ???
after the cycle of intake stroke  the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful. 

what is combustion stroke ??
When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down. 

what is exhaust stroke ??
Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe. 

Now the engine is ready for the next cycle, so it intakes another charge of air and gas.

Notice that the motion that comes out of an internal combustion engine is rotational, . In an engine the linear motion of the pistons is converted into rotational motion by the crankshaft. The rotational motion is nice because we plan to turn (rotate) the car's wheels with it anyway.

what is The ­principle behind any reciprocating internal combustion engine

Internal Combustion is The ­principle behind any reciprocating internal combustion engine: now the question arises what is internal combustion engine guys in car engines we need to have more energy but the space from where this energy is to produced is small so the basic principle of internal combustion engine is if you you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet. In this case, the energy is translated into potato motion. You can also use it for more interesting purposes. For example, if you can create a cycle that allows you to set off explosions like this hundreds of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car engine!this is the basic principle behind the car engine ....

principle behind cAR working????

Compared to other technologies we use every day, it seems like car engines haven't really changed much. The engine in an old Ford Model T has plenty in common with the engine in a 2011 Ford Fusion, but it's doubtful Alexander Graham Bell would know what to do with an iPhone. While communications technology has changed drastically, car engines use the same basic principle: The combustion of air and fuel to create rotational force and move a car.
But while the same basic principles that drove the first car engines are still used today, modern car engines have evolved to meet the power and efficiency needs of today's drivers. Think of older car engines as wolves and modern car engines as dogs. They're share the same heritage and have similar characteristics, but one does just fine in everyday modern situations, while the other just couldn't adapt to living in a city or suburb.
Before we talk about how modern car engines are different from older ones, you need to understand the basics of how a car engine works. Basically, gasoline and air are ignited in a cylinder. In the cylinder is a piston that gets moved up and down by the gasoline/air explosion. The piston is attached to the crankshaft. As the piston moves up and down, it makes the crankshaft rotate. The crankshaft goes out to the transmission, which transmits that power to the car's wheels. Sounds simple, right? With modern engines the basics still apply, but there's a lot more to think about.Your basic gasoline car engine isn't all that efficient. Of all the chemical energy in gasoline, only about 15 percent gets converted into the mechanical energy that actually moves the car. The EPA says over 17 percent of the energy is lost as the engine idles, and a whopping 62 percent is lost in the engine due to heat and friction.
Modern engines have a number of technologies in place to make them more efficient. For example, direct injection technology, which mixes the fuel and the air before they're put into the cylinder, can improve engine efficiency by 12 percent because the fuel burns more efficiently [source: U.S. Department of Energy]. Turbochargers, which use compressed air from the car's exhaust system, compress the air that's used in the combustion cycle. The compressed air leads to more efficient combustion. Variable-valve timing and cylinder deactivation are technologies that allow the engine to use only the fuel it needs, increasing efficiency.

There's a common misconception that efficient engines are underpowered engines.

what is a v8 engine

hello guys this is my first blog on cars so let me be very clear on what i will be sharing on this blog ....
everything that i know and would also love to listen from you what you will like to read 
so first query will be 

what is a v8 engine 

A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft.

In its simplest form, it is basically two straight-4 engines sharing a common crankshaft. However, this simple configuration, with a single-plane crankshaft, has the same secondary dynamic imbalance problems as two straight-4s, resulting in vibrations in large engine displacements. As a result, since the 1920s most V8s have used the somewhat more complex crossplane crankshaft with heavy counterweights to eliminate the vibrations. This results in an engine which is smoother than a V6, while being considerably less expensive than a V12 engine. Most racing V8s continue to use the single plane crankshaft because it allows faster acceleration and more efficient exhaust system designs.
