Transparent steam engine!



Was not the steam engine driver of trains and ships, but also the impetus of the industrial revolution, which contributed to change the world.
How was the work of this engine?
To watch the answer through this form transparent glass:


Vintage Air is heated water vapor, which converts thermal energy to the movement! A simple idea and a great way to explain!

(Fuel Cell) technology and impressive in the world of cars (search Tqnicy )......

Introduction: -

Cars, we can not deny it's one of the most important inventions in human history where it According to the latest statistics more prevalent methods of transport in the whole world.

As we know the car did not invent the one-time or on a particular world, but is passed through stages of development of longitudinal over two centuries to reach this figure, which we use Haleao so far and I am still in constant evolution and expressed to improve and develop.

The aim of modern scientific research, which seeks to develop the car towards a single goal is to increase the capacity or improve the car this is not the only form in the first place, while the main concern now is to reduce pollution and harmful emissions coming out of the engine.

Today will be talking about new technology and a very, in my opinion will make a revolution in the world of cars if they have already started this coup, a means clean and energy efficient it is fuel cells.


History of the development of fuel cells: -


Can say that it was the invention of fuel cell technology and the Shaman by Sir William Grove Welshman Sir WilliamGrove in 1839 as the invention of the battery voltage gas gas voltaic battery is the one who gave the scientists then Tfnah the principles of the fuel cell.

The idea of ​​simple battery Grove is the basis of the emergence of fuel cell technology, but this name does not appear physically, but in 1889, by Charles Wenger Charles Langer and Ludwig Mondz Ludwig Mond's where they first tried to industry's first cell and the actual fuel.

In 1960, used NASA NASA - national aeronautics and space administration technology of fuel cells practical for generating electricity and running a car space a small spacecraft and then under development in fuel cells continues in the seventies until the early eighties when it began to enter the auto industry - and this is what concerns us in topic - fuel cells and remained in the testing phase and develop until the mid-nineties and reached a stage that it could be used in cars as the increased size and efficiency are well and in the next few lines I will explain how fuel cells work developed in detail, God willing.


What are fuel cells?: -


Is simply a device for converting chemical energy to electrical energy as the fuel cell works to convert hydrogen and oxygen into water, and through this interaction produces an electrical utilized it.
We can metaphorically say that fuel cells are similar to the battery as it generates electrical energy from chemical reactions, but the difference here that have a battery lifespan while the fuel cell where it is not final as long as it enters the hydrogen and oxygen out electrical current. And fuel cells compete strongly many other sources of electricity generation such as gas turbines and gas turbine power plants mega city's power plant so it's competing small battery that could use them in the operation of laptop LapTop. The main reason for the superiority of fuel cells for the rest of the sources of power mentioned above is to increase efficiency as the most severe of these sources using fuel burning for energy, increasing the pollution and the resulting energy is not a force that may produce the fuel cell. Types of fuel cells: - Proton Exchange Membrane (PEM) It is considered one of the best types of fuel cells and the smallest in size for energy resulting from them. In this type of membrane used polymer in the solid state and this reduces the reaction temperature and increase the efficiency and faster in the start and the response. This type of fuel cells is the most prevalent in the world as it is used in the fields of cars to the small size. Alkaline: - Alalcalayn used in this type of fuel cells, but the main problem of this type despite the strength of the current output is that it requires pure hydrogen and pure oxygen quite well to begin this type of interaction and is one of the oldest types where invented in 1960 Phosphoric Acid: - This type is not used in industry because of the large size and increase the reaction temperature strongly Alalktrulad eat and sometimes because of the heat. Molten Carbonate: - This type of fuel cells more complex as it requires high temperature to start the interaction in addition to its great size and is used in power plants Solid Oxide: - It also requires high heat to start, but the interaction is characterized by lack of oxygen and hydrogen used to generate the same amount of energy compared to other types. From this we see that the first type is one that concerns us in this report and this is where he was the type used in cars and I will speak the following lines in the curse, God willing, I will explain in detail how it works and its features to that he was interested in this topic.


Proton Exchange Membrane
· Anode
· Cathode
· Proton Exchange Membrance
· Catalyst


And simply adopt the idea of ​​his work on the movement of hydrogen atoms from the anode to the anode-cathode atoms of oxygen in the cathode and their interaction with passing an electric current is generated and the reaction product is water, and the following equations describes the work: -




Anode side:
2H2 => 4H+ + 4e-

Cathode side:
O2 + 4H+ + 4e- => 2H2O

Net reaction:
2H2 + O2 => 2H2O



Minute detail the method of work:


Anode side: Be paid to the cathode and oxygen passes through the catalyst, which catalyst is splitting an atom of oxygen to the Ionians Salpin O-

Cathode side: 
As you can see is compressed and pay atoms of hydrogen to the fuel cell in terms of anode - the anode - and when entering the compressed hydrogen to a Calcined first pass through the catalyst catalyst and the catalyst is splitting of the hydrogen atom H2 to the ions of hydrogen, the positive H +, H + and results from this fission two electrons e-.

These electrons are the cause for generating electricity and then complete the circuit path where the rush of positive hydrogen ions on the negatively charged ions of oxygen to unite together and be water as the previous equations.

He graduated from the single cell fuel cells almost 0.7 volts and is connected to more than one cell in a row to get the required voltage value.

And reflect the main problem in this type, which hampered without entering in the field of cars for a long time is that, to generate energy from it we need oxygen and hydrogen for oxygen, it is easy to get it from the air and available, but the real problem was in the hydrogen as it does not exist except in the upper layers of air and extracted was somewhat difficult, therefore, scientists are looking for another way to generate hydrogen is energy

But in the end reached to the way the process is very effective and is dependent on the conversion of hydrocarbons or alcohols (alcohol fuel) to the hydrogen can be used in fuel cells, and this by a device called a re-writing by the mediator or AlkamiaĂºy reformer.

But as nothing less than full, as the way out of this high temperature and the outside is pure hydrogen, which reduces the efficiency of fuel cell
The recent research conducted by scientists have now found that he could Alastagadah for hydrogen with natural gas - and that land and methane - propane and methanol as easy access to natural gas easily.

Tangier's more methane gas nominations to be used in modern cars, for easy access and easily cut in it.





Are fuel cells really the best?

Perhaps the question that may come to your mind now is the best fuel cells for use in cars or not? Do you give us the highest efficiency Tholha match for the techniques currently used. This is what we will discuss it in the next lines, God willing.

In order to know whether the fuel cells are already the best, we will first study the efficiency of the car when using fuel cells and efficiency of the car when using traditional heat engine, and also the efficiency of the car when you use the electric motor and then we can determine the best players.
First: - fuel cells and vehicles: -

According to the tests of modern vehicles using fuel cells, found that if we have the use of hydrogen refined completely, it can get the energy efficiency of up to 80%, but as we have explained before that he can not get pure hydrogen easily, especially in the car, so it is used instead of it alcohol fuel or hydrocarbons, but it is pure hydrogen out completely, causing a shortage of efficiency to reach 40 to 30%
About.

This is for the emerging electric power in cars still need to convert this electrical energy to kinetic energy through the motor and the last tests that resulted in almost reach the overall efficiency of the final Li emerging in the form of kinetic energy from the motor up to 32% to 24% approximately.
Second: - heat engines and cars: -

Heat engines are the engines that use fossil fuel - diesel or gasoline - in the generation of thermal energy by burning the fuel and the shift of the energy to kinetic energy. This is the traditional engine used in cars as a whole.

According to tests that have been made on this type of engine to find out the actual efficiency learned from this engine and do not be surprised of it but found in practice that the overall efficiency of this type of engine is very, very low up to 20% only !!!!!!!!!

Do not be surprised of the number, but it is actually where the heat generated by burning fuel in the form of heat lost with exhaust gas from abroad or lose during the cooling cycle in the car and no need for Mufaqad to mention the other in the gearbox and the crown, if any, etc.

Third


: - electric motors and cars: -

Electric motors found in cars for a long time and is based on the idea of ​​having the electric motor traditional battery-powered

And tested on this type of engine and you may be surprised for the second time he has a very high efficiency up 72% overall efficiency of almost
This means that the best species to use and the killer but the disadvantage in this type of need is permanent to the shipping of the batteries and therefore is used as in enclosed spaces such as golf courses and large companies and universities (in developed countries, of course J).

From the above we can judge what system the best and highest efficiency in the use in cars, but it should be noted that the technical standards found that this was the best kind of car, or not
These criteria are: -

1 - Is the car easy to use and scalable for maintenance.
2 - Is the car easy to re-fuel or energy Altdhuad
3 - What is the distance to go before it can be re-powered Altdhuad
4 - How is the speed compared to other vehicles
5 - What amount of environmental pollution caused by

Of course, we can now answer the question ourselves, which is that fuel cell technology and deservedly overtook the techniques currently available.



Fuel cells and used in cars: -
Initially started using fuel cells in large vehicles, especially buses Buses in the large size of the fuel cell in the beginning, but with the small size of the continuous development of fuel cell is so make it suitable for use in small cars..





Has already begun to hydrogen fuel cells type PEM Previous explained in the entry in the automotive world is supposed to replace the cars with conventional engines in the very near future and is expected to begin widespread in cars after 2010 and the cars existing current use methylene As we have said before There are also some companies have developed a special type of fuel can be extracted from hydrogen and companies are still at the moment is trying to develop other ways to extract hydrogen in a better and purer order Tved the efficiency of the fuel cell.


Examples of vehicles using fuel cells at this time: -

Spread in recent cars that use fuel cells and I think most of us have heard about cars running on hydrogen, which are the same cars that fuel cell

I have heard that the former actor and California Governor Arnold Hoaznniger this has been giving it a car Hummer H2 and operating technology and fuel cells as a gift in recognition of his efforts from Hammer Company beautiful (which I do not know explicitly).

This set of pictures of the cars available on the market now and works with fuel cells.

Jet Engine ::How to produce the momentum??



Jet engine is the engine exhaust fluid (water or air) at high speed to produce a driving force based on the principle of Newton's third law of motion. This broad definition of jet engines includes turbojets, turbofans, rockets, ramjets, and jet pulse, and pump-jets. But the verbal common means jet engine: Engine Bretton-cycle gas turbine, or short, the gas turbine compressor of a gas-backed push air or water him, and that produces the remaining capacity of the payment or the driving force. A people that the gas turbine is defined as one of the applications are separated from the jet engine, rather than the other way healthier as part of jet engines are internal combustion engines  without showing any form of outside combustion engine. 


Used jet engines mainly for aircraft with long-term, Aircraft old used engine turbine jet is not the same efficiency required, prompting the models modern of these jet aircraft using engine turbine helicopters with Ext major side, which has helped to increase the rate of speed, range and security of the better efficiency of consumption fuel in the aircraft of other transport vehicles. So that the rate of consumption of the jet engines of world consumption amounted to 7.2% in 2004

Jordan could invent a car engine reduces fuel consumption 70% (Asender engine)


Asender engine

Jordanian citizen of installing a new engine on a car

As an alternative to the current drive ability than about 20 times the capacity of a traditional engine and reduces fuel consumption by 70 percent.
The advantage of the engine which was invented by Mohammed Khalil Asendr small size, light weight and longevity for adoption on the "rolling" and the lack of friction between the pieces and reduce the rate of emission of harmful gases to the environment.

The advantage of being free of the problems of cooling and lubricating the motor facing the traditional reliance on air cooling system four-stroke internal combustion according to the inventor.

He told the Jordanian news agency that although the capacity of "new engine" of 800 cc

However, the magnitude of engine power than a conventional (20) times and cut fuel consumption by 70 percent for the consumption of conventional vehicles where the engine enables the car to walk a distance of 700 kilometers every twenty liters of petrol.

Asendr / 53 years /

That the engine that has been done in three years does not need maintenance for a few breakdowns, adding that he can be replaced in the event where his unemployment weighs more than "70 kilograms" shall not exceed the price (thousand) dinars.

He pointed out that this engine, which was adopted by 37 industrial nations including the United States, Japan and European countries by Talal Abu-Ghazaleh Intellectual Property register.

The Regional Director explained to the patents in Talal Abu-Ghazaleh Intellectual Property Engineer Ahmed Zoubi that the institution is the authority for registration of a patent, Mr. Asendr in various countries around the world, pointing out that the institution concerned, through its seventy-deployed around the world registered patents, trademarks, industrial designs and copyright .

Asendr reviewed the obstacles it faced in the implementation of the invention, which is limited to the lack of technical means, technical and equipment needed, which arranged for engineers implementing the extra mile.

Action Asendr holder of a high school in the public sector as a technician mechanics and moved to the United Arab Emirates to work in the field of transport and shipping.

He Asendr hope to contribute to his invention in the face of rising prices of oil derivatives by reducing the rate of spent fuel in vehicles is now reducing their prices after the adoption of his invention, which reduces the pieces made from 300 pieces to 156 pieces thus saving cost as well as providing new job opportunities in the States implementing the invention.

Succeeded in the invention, motor vehicle engine




Germany marked the public and the city of Augsburg, especially the birthday anniversary of Karl-inventor of the first diesel engine of the car, and set up a whole year in his home town of Augsburg celebrations to remind him and Pachtrall who "move the world."

Munich: A car has become an important part of human life, many people are interested in all types and brands of global and Sallonatha luxury, do not stop asking for new and exciting in the automotive world. On the other hand there are very few who are interested in the automotive industry on how the idea originated? It is the inventor? What is the most superior in this industry?

In southern Germany, specifically in the city of Augsburg, which witnessed the birth of the great German inventor Rudolf Christian Karl Diesel, we find the answer. In the eighteenth of March-March 1858 was born Karl Diesel invented the engine car in the world in the city of Augsburg, Germany, on the occasion of his birth in each year the city holds a number of festivities to remind the present inventor, the great and the continuing appreciation and gratitude and recognition thanks to mankind in the field of movement mechanical, so he is nicknamed in Germany, "the man who moved mankind."

To look at the history of this man, and read in the extent of his genius and Nbogth will be useful for anyone interested in cars. Born Rudolf Diesel to parents Germans migrants in Paris, and since childhood, I realize that his parents over Nbogth and his scientific, where he showed his great love for the Engineering Science and Mechanics, which allowed him at the age of twelve to get an award from a French institutions as a reward for excellence course. Following this, his parents sent him to a relative in the city of Augsburg,''''in southern Germany where he joined the school where industrial, and qualified them to join the Munich University of Applied Sciences .. And which began a new chapter of his life to achieving his dream of a scientific study and engineering excellence.

Realizing the Dream

The diesel is a student in his twenties has always seen the steam engine which consumes energy-intensive - and the user is that in industrial plants and mechanical machines, ships and others that the invention is not practical, and began the idea of examining how the invention of an alternative is powerful, energy saving, and is even less expensive his mind all the time.

He believed that each invention is the product of two elements: one idea Alakralttbaiq the philosophy that made his imagination fertile of Science in Mechanical yield the idea of the invention of the first engine based on the principle of internal combustion converts the chemical energy inherent in the fuel to kinetic energy in 1890, which means getting on the engine with more efficient compared with other engines are common in that era, and chose his name, "Otto Motor."

Thus began the Diesel 1893 with his research and experiments for the invention of a driving force in company factories MAN engines in the city of Augsburg in southern Germany, which made him 600000 Mark in cooperation with the King of the steel industry in Essen, then-''Friedrich Krupp''for research on new engine has required hard work and several years of research and experience has been subjected to many of the frustrations, he questioned colleagues at the possibility of the test's success as his life was in danger during a test when the engine exploded and tore a piece in the air, almost takes his life and his.

However, the birth of his dream difficult become a reality by 1897 as it allows it to run the engine for the first time and was strongly twenty horsepower, this invention is the latest major coup of Science in Engineering Mechanical and scored the invention in his name''Diesel''a name that holds the engine so far, and still first version of the engine and the same way envisaged by the Copyright in the Global Technical Museum in Munich today, and is keen to see young engineers from all over Germany and the world.

Revolutionary new engine
