Of intercoolers and radiators

what is the difference?

A radiator appears in all cars as a means to cool the engine down. As you probably are aware, if fuel and oxygen are burned together they'd heat up the surrounding area pretty quickly. It isnt very good for the metal in the engine to just melt away so we need a coolant. The engine is surrounded by a "jacket" filled with water. This water is circulated by the radiator
in a sequence like this

radiator--> cool water-->jacket-->cools engine--> water heats up-->hot water--> radiator--and so on


Intercooler

A turbocharged or supercharged car uses the chargers ability to grab LOTS AND LOTS of air from the atmosphere and chuck it into the engine.
I would like to stress that when you grab all this air, and COMPRESS it, the air heats up which isnt very good coz hot air expands, and so if it expands, it will escape. Totally defeating the purpose of the charger.

Therefore you need an intercooler, a device usually placed where air can come in at full speed,
(hint: front of the car, or at the bonnet, sometimes you see a big whole on the bonnet)
the air flows ontop of the intercooler, and cools down the air INSIDE the charger.

Makeover almost complete

Finally, got rid of that clunky, clicking, rattling steering wheel. . . .

....for this one.

Peek inside
Finally a good sunny day to take photos.

Andai daku pergi sebelummu
Kenangkanlah ku selalu didalam doamu
Kaulah cinta pertama dan terakhir untuku
Ku berjanji kan menantimu
Setia menunggu di pintu syurga

Jotted down

Just need to type this out, in case I lose it somewhere, I have a habit of losing things.

Zinzadze reagent
1. sodium molybdate (1 g) dissolved in 4 N Hydrochloric acid (1o ml) - Solution A
2. hydrazine monohydrochloride (0.1 g) dissolved in water (10 ml) - solution B
3. Both solutions are mixed and heated on a boiling water bath for 5 mins.
4. on cooling, the mixture is made up to 100 ml with distilled water.

Orcinol Reagent
1. dissolve 20 mg of orcinol in 10 ml of 70% sulphuric acid (conc 98%) (20 ml acid, 8 ml H20)
2. solution to be kept in 4 degree C for 4 days only.
3. prepare the sulphuric acid dilution in an ice bath to ensure the vial remains cool.


***4 N HCL***

d (HCl stock) = d1
% HCl stock = p

(d1 . p/100)/mw HCl= M

Volume of HCl used = 4N*1000 ml/ M

gone

-blog will be stopped till further notice-

no more light

I hope it ends one day.
Continue on sleeping for a thousand years.
Never wake up.

I feel no hope.
Feel no strength.
Theres no more light.
Just a freight train coming my way.

My collection of Star Wars books...

...has expanded!

woooot
in case it wasnt obvious, its in bold yellow letters.

lol , lollipop, i must blog this

Glossary of Automobile terms Part 8

This isnt so much a glossary, but more of a tip on how to change your wheels when you get a flat. I know I know most of you know how, and if I say that this guide is especially for the ladies omg you'll call me sexist I dont care coz most of the time its true, non of you ladies bother changing your wheel.

So here's a little guide anyway.
First grab your tools from the trunk of the car.
You'll need the jack.
First the jack is placed under the car, near the tyre you want to change. You can see the groves where the jack must go. The jack must not lift up the car yet. Instead after a few times of pulling the jack lever, grab the appropriate sized tools to loosen the nuts off the wheels.

Done?
Now you can start jacking up the car till its above ground. Proceed to unscrew the nuts completely. Now remove the flat tyre along with its wheel, and place your reserve wheel accordingly.
Replace the nuts, and screw them in but not too tight.
Lower the car, and proceed to tighten the nuts.

Now that may sound simple. To most ladies, this isnt difficult. In fact, its a no brainer.The real problem lies in the greasy bits. The nuts are greasy, the jack is greasy, heck, the whole tire is dirty.

This is what you ladies need to have in the trunk of the car,

1. Gloves, to not get your hands and nails dirty.
2. apron, because when you remove your tyre, most likely the tyre will brush against your top and stain it. boohoo.
3. Keep a small bottle of nail polish remover in the car also. The nail polish remover helps clean up any grease on your hands or arms during the process.
To all you geeks, nail polish remover can also be replaced by acetone. But please keep the acetone away from papers which have ink on the them.
4. A big old towel you can place on the floor of the road, so you dont have to put up with the dirty road.

Glossary of Automobile terms Part 7

Superchargers and Turbochargers are not meant to make the car go at high speeds, but to make the car accelerate quickly from 0-100 kmph. Because when you're in traffic and need to overtake, acceleration is more important than top speed. Who can reach top speeds on Malaysian roads anyway?











Thats my artist rendition of what the turbo charger and engine look like in simple diagrams.
Exhaust passes the turbo, spinning the turbine,
Turbo sucks in air from outside, it collects and pushes it into the engine.


A summary of the post on superchargers and turbochargers

So we all know that
to get more power, we need more fuel, therefore we need more air.

To get more air we need a pump or a reservoir or a collection of air and hold it at high pressure. (thats the chargers job)

The air will be pumped into the engine from the charger,
combined this with ALOT of fuel being pumped in,
we get ALOT of power.

Glossary of Automobile terms Part 6

TurboChargers
and
Supercharges


What the hell is the difference?

1st we must understand

What do they do? and Why?

Why?

A car needs air and fuel to make the engine spin. (remember 1 spin = push bang blow suck)
For every 2 unit of petrol, you need 25 unit of Oxygen.
Therefore, for every 2 million unit of petrol you need 25 million unit of Oxygen.

However, this world is not perfect. So for every 2 million unit of Petrol, you only get about 20 Million of Oxygen. Thats not enough. So you dont get much power.

To get more power, we need more fuel. Therefore, more fuel means we need more Oxygen.
A Supercharger is able to collect ALOT of air (Oxygen) and push it into the engine.
Therefore a supercharger is able to increase the power of your engine. (of course that means you can go faster la)

Basically:

A charger :
collects something and releases it so it can become useful.
Eg. Electric charger takes in electricity from your wall socket, and releases it into your phone battery.
Rhinocharger, a rhinoceros from africa running at you and will kill if you dont avoid it.

so a turbocharger or supercharger takes in air from the surrounding atmostphere, collects it, and pushes it into your engine.

A simple example

If you are running very fast, you will soon feel like you dont have enough air to breath, thats because your lungs can only grab as much air as the lungs can hold. But if you put some kind of pump, it will push that air (ALOT OF AIR) into your lungs and force it in (ngehehehehe). (of course you will need that pump to pull out your carbon dioxide too otherwise you will die of asyphixiation.
(But in the real world pumps are heavy and will weigh you down, so how will you run fast in the 1st place? -_______-)

So now you know what turbochargers and superchargers can do. Lets see HOW they do it.
Superchargers.
An engine has what are called Pulleys. These pulleys make sure ALL the shafts, cams, timing belts, alternator, air con compressor all turn at the same time. (A pulley is a type of wheel attached to a belt)
A crank pulley (CP) is a pulley that turns according to the engine speed. If engine is moving at 2000 rpm, the pulley turns at 2000 rpm.
A supercharger also has a belt that will connect to this pulley. And so, as that pulley turns, the supercharger pulley (SC) turns.
The SC will then move a few gears inside the Supercharger and this creates a motion that will pull in air from the atmosphere. It will pull it at very high pressure. This air will then be pushed into the engine.

Turbocharges
Almost the same, except, a turbocharger uses gas to turn the TURBINE inside the charger. (Turbine , so thats why its called Turbo, like your aeroplane is a turbojet, it uses turbines)
Where does it get the gas from?
AHA!
The gas that comes out from your engine is called Carbon Dioxide, CO2. This CO2 comes out at very very high speed. Therefore, with that speed, it can pass the turbine causing the turbine to spin. (THE CO2 GAS DOES NOT GO INTO THE ENGINE AGAIN)
The turbine spins causing air from outside to be sucked in and this will be charged at high pressure, then it will be pushed into the engine.

Will continue later about turbochargers and superchargers.

See the shiny silver thing, thats a supercharger.
See the siput (snail) looking thing, thats a turbocharger)

no mood

No mood to blog after whats be happenin lately. Aih.

sigh. Dont worry babe, it'll be alright soon. And weesa gotta sometin nu for yu.
