All about Engines...

Posted: 13 Feb 2011 06:06 AM PST

Hello all,
I always used to wonder what engine is like.I basically didn't knew that an Engine may contain more than one piston cylinder arrangement.But its actually fun.
We normally just memorize the name by heart without thinking of its meaning.So let us take an effort to know what are different types of engines. There are also different types like Adiabati engine,Rotary engine,Wankel engines etc.
Engines are classified by following parameters:

1.Number of cylinders
there are generally 1,2,3,4,5,6,8,12 cylinder engines.It means that let say 4 cylinders are cascaded to form a one unit.Also known as 4 cylinder engine.

2.Arrangement of cylinders
The cylinders may be arranged in single line or in two rows.Half on both sides.So when you say V8 engine.It contains 4 cylinders each in 2 rows.When seen from front i.e; front view resembles English alphabet 'V'.Hence the name.

3.Arrangement of valve and valve trains
You may say these are the lungs of Engine.With the help of these air fuel mixture or simply air or 'whatever the engine is designed for' enters the engine.
There are several different arrangements of valve and valve trains.
a.Location of cam shaft
b.How the camshaft is driven
c.Types of valve train
d.Number of valves per cylinder

4.Type of cooling
This is a cooling arrangement.Basically a radiator arrangement.Ever seen a radiator? Yes you have.See any rolls royce on internet.On the front portion you will see net of black colour.that is actually the front portion of radiator.

5.Number of strokes per cycle (2 or 4)
The most powerful engine is 2 stroke engine.Because power is developed every alternate stroke.while for 4 stroke engine power is developed once in 4 strokes.
So a 2 stroke engine produces twice the power than a 4 stroke engine.

6.Type of fuel burned in that engine
Spark ignition engines usually burn gasoline or gasohol.It is a mixture of gasoline and alcohol.Some spark ignition engines especially in buses and trucks burn LPG or CNG.Diesel engines usually burn a light oil called diesel fuel.Flexible fuel vehicles can burn gasoline or alcohol blend fuels.

7.Method of ignition
In petrol engines the cycle used is Otto cycle.The air fuel mixture is first compressed and then spark is applied.
While in diesel engine diesel cycle is used.First only air is taken in and compressed and then a jet of diesel is applied 'igniting the air' in layman's terms.

8.Firing order
Firing order is sequence in which the cylinder deliver power strokes.Like in 4 cylinder engine the sequence is 1-2-4-3 or 1-3-4-2.It should be noted that all cylinders perform different processes at different times.When first cylinder is in power stroke other cylinder may be in suction while other is compression and remaining one in expansion stroke.This ensures uninterrupted generation of power.

9.Reciprocating or rotary
The engine may be reciprocating or rotary depending on what mechanisms are used.

What I tried to explain is a conventional system.Correct me if I am wrong anywhere.Those who are in their jobs may share their experiences with us.Because there is ample opportunity of innovation.

The Philippine National Proverb
Translated into various Philippine languages...
With over 168 mutually unintelligible languages, the Philippines is a country of incredible linguistic diversity. This illustrates some of that diversity with the national proverb, translated into various languages of the islands. The translations are arranged geographically by island (and island area), not genetically (by language family). Philippines is composed of 7100+.

"He who does not (know how to) look back at his past (where he came from) will not reach his destination."

giving statements

Posted: 13 Feb 2011 05:27 AM PST

hey friends
we are lisning many people giving there statements regarding improving our country
why cant we give them
here is mine
"give me some hands of supports i will make my India as a supreme power in the world"

come on ceans lets give our own statements

Do Google sell our personal information.

Posted: 13 Feb 2011 04:59 AM PST

Hello CEans. I found this information on some site. And I wanna share it with you.:)

How does Google know everything about you?
They don't.
Google only knows your public information (are you listed in the phone book?), what you put out there on the internet publicly, and what you tell Google directly via means of using one of Google's products (YouTube, Panoramio, Gmail, etc.) This means that for whatever you put out there on the public internet, Google can index indefinitely as long as it exists.
The Big Question however is: Does Google sell the data it indexes about you?
Short answer:
No (mostly).
Long answer:
The best way to explain this is by citing two specific Google products, Gmail and YouTube.

GMAIL
All emails you send and receive are machine-read in order to deliver what's called "relevant advertising" while using the Gmail product in the browser (meaning not IMAP or POP3). When the machine-reading reads specific words, be they in the subject line or body of the message, ads are displayed relevant to those words. For example, if you received an email with the word Florida in it, you'd probably see an ad about Disney World in Gmail. That's not coincidence.

YOUTUBE
When you sign up for YouTube you are prompted to enter in some demographic information (age, location, etc.) If you do this, the video ads you see on YouTube on specific videos may be specific to your demographic.

THE REAL BIG QUESTION
The Real Big Question is: Does showing relevant ads per your email content and/or demographic information count as your personal information being sold?

If you want to get really technical about it, yes – but barely, and I mean barely. Your information was indirectly keyword there) given to advertisers by means of Google's advertising system to deliver relevant advertising to you. However it is very important to point out that only Google knows what you gave them, and furthermore the advertisers that use Google's advertising system do not know you as a person unless you actually buy something from start to finish from click-through of the ad (ex: Click ad, hit is tracked, you buy product, you give company your info to buy the whatever-it-is, that data is recorded by the company you bought the product from).
Put in much simpler terms: Unless you actually clicked through the ad and bought something, you are nothing more than a demographic statistic. Google still knows what you gave them for personal info, but the advertisers that use the Google advertising system do not.

It also should be noted that if you don't click the ad, not even your demographic information is given out and are merely counted as a faceless, nameless "ad impression", and that's where the 'just barely' comes in concerning the sale of your personal information.

micro processors history

Posted: 13 Feb 2011 04:06 AM PST

hi friends,
i am here with my second concept here in this thread i came with the history of the micro processors
let us first know what is micro processor
microprocessor is an IC chip with the logics and it is known as heart of the computer
it was discovered in 1960's and 1970's
in 1971 intel designed its first processor called as 4004
it is a 4bit processor we can know it seeing its name 4004 it is a 4 bit
next motorolla and many companies came into existence and then due to competitions intel introduced its 8008 processor it is a 8 bit processor it was introduced around 1972
later 8008 was came into its decay by 8080 processor it is also a 8 bit processor with a good performance capacity and higher compability over 8008
next motorolla given its 6800 processor
next intel also given its 16 bit processors 8086 and 8085 here intel came with the x86 family with a high memory up to my knowledge 8086 has the 1Mb of storage and between many capacities of segments like stack etc.....,
later many processors came into existence and we are using 64 bit processors too like i3,i7 etc..,
with higher memory capabilities and with higher os running capabilities like windows7,vista,xp etc.......,



if i had made any mistakes correct me because i am still in the studying about processors and discuss about them in this thread
this thread is dedicated to discuss about microprocessors
