vision of the future of wireless power. In the future, electric vehicles may be able to charge their batteries wireless.Siemens is active in this field and develops a safe and convenient technology for wireless charging.
Siemens and BMW are partnering on a field trial for inductive chargers. In way of thinking these can be installed into vehicle parking, taxi cab, and of course driveways, sunk right into the ground.
“A clever
person solves a problem. A wise person avoids it.”
Thank you
Einstien, you are living in my heart. That was true, so that here are the top
tips to avoid hot summer driving problems
 |
| Drive safely |
- Keep a car
fire extinguisher near to you, just in case.
- keep a
large bottle of water near to you and may be some of your favorite fruits,
snacks, juice, or cold drinks. Sunburn affects your body's ability to cool
itself and causes a loss of body fluids.
- Do not
leave Children or pets in a Car alone. Even if the car was air conditioned or
the windows are open. Don’t leave them fallen asleep in the car.
- Avoid
sudden change in temperature; this will be stressful to your body. Stay one min
in your car with opened windows to gradually temperature change.
- Direct sun
exposure so harmful.
- In case of
driving or riding in a convertible, wrap your hair well, wear a sunglasses, or
wear a hat.
- Keep a
fully-charged mobile phone with you in case of emergency
- If you are
65 years of age or older, keep in contact with a friend along the way
- keep the
first aid bag

| Please Drive Safe |
2- Your car
health and safety
- Check tire
pressures, avoid tire over pressure due to hot roads.
- Check your
radiator coolant levels, and be sure there is no leakage under your car or
around the radiator, and hoses.
- Check your
engine oil levels, and be sure there is no leakage under your car or around the
engine
- Check the
cooling fan for proper operation
- Don’t fill
your fuel tank up to the brim, the heat expansion could cause a fuel leak.
- Don't splash
hot engine or brakes with water. This is
extreme thermal stress over any hot body.
- Park in
the shade.
Drive safe, and remember there is always someone waiting for you, and another one is writing this article for you :) waiting your comment too
Hybrid not
zero emission car, but Lowest emission with highest energy saving. This is great goal
in manufacturing fields.
Car owner:
can we continue now.
 |
| Hybrid Car |
Auto: sure.
Auto: A lot
of systems are involved into hybrid cars, to achieve two main propose. The first
is how to reduce the emission as we mentioned before European want to reach 95
g/km at the next 8 years.
The second is hoe to reduce energy wasting to
increase the efficiency of the car. Here is a simple operation overview to open
the understanding gates of energy and emissions reduction:
The hybrid main components are Engine, Motor, Generator, and Planetary Gear. The planetary
gear "its working as power split device" combined them to resulting
one output goes to reduction unite, hence to the differential gears. The
previous combination called "hybrid-trans axle".
An ECU
(Electronic control unite) organizing whom will be a driver and which will be
driven. Actually based on, the state of operation "start-out,
accelerating, decelerating, or stopping" the ECU is acting. The ECU sends its
signal to feed the motor by the batteries energy to move the car, or start the
engine to supply its energy to the generator which will recharge the batteries.
Also, the
engine can share its energy to run both of the car and the generator at the
same time, and both of them "Engine, Motor, and the Generator" can works together.
Auto: this was an overview, now how we save energy and reduce emissions, here is some of systems explanation shows how is that works :
This system recover the wasted energy during braking or deceleration.
During cold engine starting, Hydrocarbon "HC" emissions kept inside the car to be fully burned or purged. That improves the exhaust emissions at low temperature.
No more starting a cold engine, because this system pumping hot stored water to worm-up the engine fast this reducing fuel wasting during engine worm-up, and also reduce the HC emissions that generated at cold starting
A device installed to reduce the vaporized fuel loses, therefor the evaporation emissions is reduced too.
Auto: and that's not all, even engines includes systems help to reduce fuel consumption and increases engine efficiency beside that improving the emissions.

…….. Al Gore, July 2008
Car owner: Hello, Auto.
Auto: Hello, Dude. Why are you upset?
Car owner: they told me I have to change my car, or i will
die. Do you believe that?!!!!
Auto: I am afraid, this is true.
Car owner: what?! are You
kidding me?
 |
| Green Car |
Auto: No, but let me explain to you…..
Here we go, Facts:
+ Vehicle
exhaust contributes roughly 60% of all carbon monoxide emissions nationwide,
and up to 95% in cities.
+ Average
new car emissions in Europe are 138g of carbon dioxide per km, but the European
Union has set a target of 95g per km by 2020.
On the other hand, you should imagine how much are those
circles are complicated. Your old car is destroying the earth, and consumes a
great amount of resources like fuel, and the manufacturing materials. That’s
all to save your time and to make you feel comfort.

| Vehicle Emissions |
Here is another fact
Green Cars are no longer an option, rather a global
game-changer whose future is “when”, not “if”. Inflection point on the horizon.
Car Owner: Green Cars!!!!!
Auto: yes, Green cars. The solutions are simplified into
equation hard to be solved. We need a car with
1- Low
emissions or without emissions if possible.
2- a car
with Light weight to reduce energy consumption.
3- Stable
and safe car for drivers.
Car owner: I can’t see any problem with that.
Auto: when automakers was trying to find a clean fuel. They
found choosing between many options are not an easy thing, but finally Electric
or Nitrogen was the best options.
If they choose the electric, we will need large batteries to
store the enough energy. Large batteries are over load to the car weight and
that energy wasting. “Easy come..Easy go”.
Another problem, how
to charge batteries? Solar energy needs bulky solar cells which increases
vehicle weights, which originally we want to reduce it. Not to mention,
non-sunny countries. And we can’t plug the car along the run ways.
By the same way for liquid nitrogen, energy is wasted during
liquefaction process. Beside this, while leakage, it reduces the oxygen
concentration if poorly ventilated store area is used. Liquid nitrogen can
cause frostbite and can make some materials extremely brittle. Its explosion is
so risky.
Conclusion: electric it self is not suitable energy to run a
car. And such a light weight car couldn’t be established specially when safety
is the mean issue. Liquid N2 is not the suitable fuel too because it’s become
danger if leaked, spilled or explode.

How is hybrid cars working?
It's so easy, hybrid cars are working with a combination of three rotating devices. An engine, motor, and generator are three rotating devices combined together with a mechanical element called planetary gear Power Split Device.

what is car? Part 3
We was talking at “Part 2” about, what is engine and how is
simply working. Also, we discussed briefly how the fuel is entering the
chamber, two more things we need to talk about the 1st is (how to
ignite the fuel?) And the 2nd (how we start the engine?) so, let us
start.
How we can ignite the fuel?
There are two basic methods to ignite the fuel into internal
combustion engines:
1-
Self Ignition. (called
Diesel Engine)
2-
Using ignition system.
(Called Benzene Engine)
In fact this is one of the main differences
between Diesel and Benzene Engines. In addition to, power, speed, and size. But
we will discuss the differences later.
-
* Based on pressure and
temperature relations when we increase the pressure the temperature increases
too. That’s why we use gasoline as a fuel for Diesel engine.
* When the pressure of the
gasoline increase, the gasoline will be fire at (about 250 deg. C) without any
ignition spark. This temperature called (Self Ignition Temperature).
 |
| Ignition System with Distributor. |
* The benzene could not be self ignited,
because it’s need about three times gasoline pressure to be self ignited which
is extremely hard to be achieved (about 550 deg. C)
* Spark-plug with spark Distributor
is needed to firing the fuel at Benzene engines, with certain firing order. But
some cars distributor-less or it electronically distributes the sparks to the
spark-plugs.
 |
| Distributor-Less Ignition system |
* A spark is a highly voltage
charge runs through a wire connected to the spark-plug.
*As conclusion if u r using
diesel engine, you don’t have ignition system. But if you have benzene engine
you may have distributor or distributor-less ignition system.
But how the engine start, this will be our
next part, Go check part 4

My girl friend, she is have strong and smooth body, a
beating heart “little faster but, its ok.”, a thinking brain and, a flowing
blood. She can breathe, dance, drink, eat, and even she feels my sensation “yup,
she is”. But she is blind “So poor :-(“. So I promised her to spend my life
driving her along the off roads.
This is true; cars bodies are made to be smooth to reduce
air resistance, and strong in case of accident. Engines works as a heart to the
car and its beat is varying between 800 rpm to 6500 rpm. The ECU (Electronic
Control Unite) plays as the brain so that, its can think. Liquids are flowing
inside the engine, brake, and the cooling system. It can breathe and drink (Air
+ Fuel) the Air-Fuel mixture, Dance when you drive it. Finally, eat your money

what is car? Part 2
But, how is that working together?
A great car designer’s are working to establish the
relations between the discussed main parts.
When the relations are established, the car goes acting like
human being.
Let us knew briefly, what every part is doing to establish the
relation.
1-
The Engine (Internal Combustion Engine).
What is the engine?
Engine is a mechanical device, which convert energy that
exists due to combustion of air-fuel mixture into a rotational movement.
[Chemical energy to Mechanical energy]
 |
| 4- stroke Engine |
The moving side (called a piston) connected by mechanical components (called connecting rod) to a type of rotating shafts with special design (called Crank Shaft). This arrangement of parts forces the crank shaft to rotate. Now the movement is established.
This cycle repeated, entering the mixture, increase the mixture pressure, firing the mixture, and let the exhaust exit.
Every step of this cycle called a stroke, which means we have four strokes in one cycle and that gives the engine another name (four – stroke engine).
Engines commonly have an arrangement of 4, 6, 8, or 12 cylinders.
Those may be arranged v-shape or in-line.
How dose the air-fuel mixture entering the chamber?
 |
| Fuel System |
There are too many ways to entering the mixture into the engine chamber. The old way is called carburetors but after development, a new era of injection systems and turbo chargers are appeared.
Injection systems are the responsible part to inject the fuel into the engine chamber while turbo charger increases the rate of air charging.
 |
| Bosch Fuel Injection System |
The four valves for each cylinder are commonly used. The 4 valves are divided (two valves for the intake, and two for the exhaust). A driving shaft (called camshaft) is swing the valves into open-close position.
But how we can ignite the mixture inside the sealed
chamber?
What is gasoline and petrol? And what is the difference?
All will be answer follow the next part, to be continued……

Are there classifications for
cars?
Yes, there is too much
classification or categorizing method here are some of my opinion
1)
Classification due
to usage:
2) Classification due to numbers of passengers:
f)
(28~50 passengers) bus.
for example check the next link:

| FHWA Classification Chart |
5) Classification according to number of axis:
6)
Classification due
to vehicle weight :
7) Classification according to manufacturing country :
As shown above cars can be classified to million ways. Check another article at Wikipedia
but this is not the end, every day a new brand or modification is exist, on other hands care model can be classification or categorizing method.

5- BAS (Brake Assist System)
What is BAS?It then provides very high braking power, even when the driver is only pressing gently on the brake pedal.
When this is used together with anti-lock braking systems, it success in faster and safer braking.
 |
| BAS Action chart |
Some road tests show that a driver requires up to 240 feet (73 meters) to stop a car heading around 60 mph (100 km/h).
In the same circumstances, cars with brake assist were able to come to a complete stop in as little as 130 feet (40 meters).
Since it only takes one-fifth of a second to travel a car length at highway speeds, the superior speed with which the brake assist is able to react also accounts for its improved safety results over traditional braking systems.

4- LSD (Limited Slip Differential)
A limited slip differential (LSD) is a modified or
extracted type of differential gear arrangement that allows for some
variation in rotational velocity of the output shafts, but does not
allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place
of a standard differential, where they convey certain dynamic
advantages, at the expense of greater complexity.  |
| LSD Effect On The Road |
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all.
In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely
the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices.
For more demanding use, such as driving in mud, off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

3- EBD (Electronic brake force distribution)
What is EBD?
When a rotating wheel is subjected to excessive heavy braking, it is prone to lock-up. In motor vehicles,
the anti-lock braking system (ABS) works to prevent this by monitoring wheel speeds and taking action in the form of releasing pressure on the braking circuit, when a rapid deceleration occurs in any of the wheels to ensure steering and vehicular control is maintained during heavy or emergency braking. This has its disadvantages though, as different amounts of braking pressure are required to lock a rotating wheel on different surfaces.
 |
| EBD Operation |
here is an example to explain how EBD work, less braking pressure would be needed to lock a wheel which was in contact with ice than a wheel which was in contact with an asphalt road.
In a situation where the wheels of a vehicle are on different surfaces (for example the two left wheels are on a concrete road and the two right wheels were on snow), during an emergency stop ABS would detect the two right wheels about to lock and would activate, even though the two left wheels would not have locked when the right wheels did.
EBD detects such conditions and electronically controls the braking force applied to each individual wheel, and therefore maximizes the braking force to ensure a maximum braking effectiveness. The final result is more precise and effective braking under all conditions, and also makes the car much more stable under heavy braking, reducing front end dive
