Model " ڤalo " for Karl Benz in 1894 - which is used in one of the first chariot races in the worldVehicle classificationMulti- typeUse of transferFuel Type Gasoline , diesel, electricityPowered ? YesNumber of wheels 3-4Axes 0-2Name the inventor Ferdinand ڤirbestDate of Invention 1672The car is a motor vehicle consists of a set of mechanical parts are working all these parts in a coordinated manner so that lead to move the vehicle , and the car is a means of transportation most prevalent in the present era .Cars are divided into several types , including small cars own , and most owned by private individuals and use them to go to work or family navigate from one place to another and to do excursions . Including large buses used to transport passengers from a public transport scattered all over the country . Including large trucks used to transport goods , and thus is considered a key element in the industrialized nations in driving the economy forward along with the railway .The car runs on the engine , the first outbreak of the cars was in the Oil of the nineteenth century , but the real discovery of the car back to the late eighteenth century AD when making Joseph Nicholas Cuneo first model car powered Year 1769 .Cars are vehicles moving on wheels carrying out your engine used to transport passengers or goods , such as what is used in mines to transport ore . It is standard practice that the car does not enter , including what is going on rods . Most definitions of the term specify that cars are designed to move on the roads equipped ( paved ) , and their places of living from one person to seven people , and usually go on four wheels . Then changed the perception of the car and became current in custom is built to transport passengers , not cargo .In 2002 , there were 590 million passenger cars in the world (ie one car for every ten people, almost ) , including 140 million in the United States (ie, a car for every two people almost ) . This percentage applies also to the countries of Western Europe .History
 
Daimler in 1886Carl Benz invented the automobile gasoline powered Otto in Germany in 1885 . The record -Benz patented this car in the January 29, 1886 in the city of Mannheim . Although the credit is due to the invention of the Benz in the modern car , however, several other German engineers were working on building cars at the same time. In Stuttgart in 1886 , scored Gottlieb Daimler and Wilhelm Maybach patented the first motorcycle which was built and tested in 1885 . In 1886 about bilateral horse-drawn wagon . In 1870, the collection of German inventor Austrian Siegfried Marcus motorized rickshaw , however, this vehicle does not exceed the pilot phase.Conneaut car
 
Conneaut steam car , in 1769 AD .Conneaut is a car which was invented in 1769 of the first car in history and has been working with steam . Conneaut was an engineer in the French army and the Pachtralla in order to drag heavy equipment for the army and in particular defender . Car with three wheels and the motor was running Basitwantan , and presses Alasitwantan were driven off by front-wheel disc clutch ( transmission ) Nude without cover . What Yarouf for that car that reached speeds between 3 and 5 and 4 kilometers per hour. It was difficult because of the weight of the steering kettle of water and the weight of the car overall. And ended with the occurrence of an accident with a wall Astdam camp during one of their reviews . There is the original car is now the National Museum of Art and Industry , Paris.New types of fuel for the engine [edit]
 
Moving image represents 4 strokes internal combustion engine :1 - pull the spray of fuel and air .2 - compressing the mixture .3 - to ignite .4 - exhaust .May operate new types of fuel for the engines of the cars on the usual reduce dependence on fossil fuels of oil , and reduce the amount of harmful gases to the environment, and reduce the problem of global warming . Therefore works auto makers to invent new types of fuel , and still their findings so far, finds ample room to improve the performance and thermal efficiency .And require new fuels new technology compatibility between the machine and fuel. This includes ways to supply fuel to the engine and type , as well as preparations for safety .Engine runs on hydrogenOpens up the use of hydrogen as a fuel for motor vehicle ample room where viability is characterized by high inflammable and at the same time has a high octane number . However, the hydrogen storage is one of the problems that need attention and solution. And storage of hydrogen in the liquid state is essential from the point of expanding the range of distance , but it is not likely to stop the car and not used for a long time , since the temperature has cooled liquid during the long , non- stop use of the car leads to raise the pressure in the hydrogen tank .BiodieselExposure in the markets of large quantities of bio-diesel . However, it will be mixed with other fuels . Although the new technology to squirt fuel into the engine high pressure and provide equipment -pressure systems s allow the running of the car fuel 100% bio-diesel , but the factory insists that rate in the range of between 10 % and 20 % , where the show is sometimes difficult to pump to pump diesel . It can alleviate the diesel automatically adjusts . There are also filters suitable for the use of bio-diesel .Engine works with alcoholIn those types of motors are often used additions of ethanol . And particularly those systems with multiple injection can run Bmakhlut contain 20 % ethanol (E20), and there are cars that can use multiple types of alcohol fuel , gasoline , and usually works Bmakhlut of 85 percent ethanol and 15 percent gasoline Super -called blended E85, and can also work with gasoline only . There are engines efficiency increases by 20 % when using E85 alcohol fuel instead of gasoline. Some factories and cars currently on the development of devices to be in control and can start the engine by mixing alcohol when installed engines usual .Cars powered by natural gasUsing natural gas as a fuel for cars and facilitates the use of the use of hydrogen , which is desirable for the cheap price and the lack of what motivate gases in the cities. And approaching its validity to run diesel-powered engines , the use of gasoline engines still needs some time to adapt those engines for gas, which is lower fuel consumption . And acquires natural gas drilling as the path of the oil is extracted from fossil fuels . The result is burning about 25 % less carbon dioxide and also less harmful gases . It is considered as a fuel is suspended until the universal use of hydrogen and biogas .South Korea has been able to run 77% of the capital Seoul buses with compressed natural gas instead of diesel for use until early 2009 , as a non- completion of the complete transformation of 100% in 2010 .Cars powered by liquefied petroleum gasKnown as LPG gas that becomes liquid under light pressure . It is a series of chemical compounds such as open or propane and butane ether compounds such as Aldmethyl ether (DME). The liquefied gas can be used in gasoline-powered vehicles , and facilitates the installation of additional hardware to operate vehicle with gas instead of liquid gasoline. And facilitates the light pressure you need the design and formation of the fuel tank , it could be a cylinder with a little high so that it can be installed in place of the wheel supply units retains cart gasoline tank at the same time . Compared to vehicles that operate with methane and its derivatives such as Aldmethyl ether DME proportion of LNG output of carbon dioxide by at least 10-15 % of what is produced by vehicles that rely on gasoline. Methane is extracted directly from the biogas or wood gas . While propane and butane extracted from oil refining as by the side of the process of producing gasoline. And it shall be deemed LNG also of limited energy sources , but that does not need to produce oil . It could be argued that the liquefied gas is one additional products to be drawn during the production of gasoline and diesel oil .Engines powered by vegetable oilsApproaching the use of vegetable oils closer heavily from the use of diesel oil to run the engines. The use of vegetable oils worth the application , especially in the country's vast agricultural lands and enjoying the sun brightly .Electric car
 
Henney Kilowatt electric car with a modern control system Baltranzistur .
 
2007 Tesla Roadster electric car .Made the first electric car in 1832 was preceded by an internal combustion cars by about seventy years . The electric car is a car is superior to the internal combustion of the low point of the sound of its engine . Then do what ensued in the evolution of the two cars on the superiority of the internal combustion car for two reasons . The first is : excellence in cutting long-distance , and secondly : low weight of the amount of fuel such as benzene or diesel for heavy weight of the battery to cut a reasonable distance . He was on the development of the electric car to wait until this day to catch up with gasoline-powered car .Some cars manufactured after the test started in 2000 has been able to walk at speeds of 210 kilometers per hour , and the other can walk a distance of 400 kilometers . But it is not suitable for experimental personal use normal due to the high price and the weight of its battery . The recharge accumulator that car takes 8 hours , and this is a long time .Meanwhile, some companies in the global automotive production electric car after 2005 and offered for sale , but its battery is still a high price . Can imagine that the electric car battery -type lithium battery - equivalent to about 6000 -ion battery of the type that we use in the laptop. It encourages a lot of governments in the United States , Japan, Germany, France, industrial companies and universities to develop batteries electric vehicle , and supports governments auto companies billions of dollars to encourage them to intensify efforts on this path , majoring Europe millions of euros for research in universities to develop technology new batteries .• The United States supports the U.S. automakers about two billion dollars to improve the car batteries .• supports the Government of Germany German cars around five billion euros to improve car batteries , and car production more environmentally friendly and reduce the amount of harmful exhaust . The purpose of the development program, the subject in 2009 to develop the electric car industry in Germany , and to be in Germany about a million vehicles of this type until 2020 .• China has a major project in this area . China has missed the automotive industry usual for a period of about a century for the Western world and Japan , but they are now working to shorten this time and engage directly in the production of electric batteries which can be recharged , won the excellence in the field of batteries laptop.China will begin from 2010 onwards in the production of electric vehicle in conjunction with one of American cars and displayed in the market. China is working on the introduction of advanced technology and adapted for use within them. China is characterized by lower wage labor , and their ability to compete in the global market is great. In addition, the internal market -Jabbar , and many Chinese tempted to get a car with a high standard of living in China's annual rise significantly. China is trying to be a leader in the field of electric car to be sold at home also in order to reduce the consumption of oil products and reduce dependence on imported oil from abroad , as well as reducing the impact of rapid industrial development on what caused the adverse effects on the environment .• In 2010 the authorities began in Germany processing program to test electric cars , where it began several government departments and some large companies to import cars of this type . One of the problems lingering problem of securing user of the vehicle from the high voltage necessary for the conduct of the car, where the need circumscription voltage is about 650 volts . Also need to be tested battery heavy swallow about 120 kg of the car in case of small accidents Astdam , and should not be a reason for the ignition of the car.• From the other hand, the re- charging the car with electricity generated by coal and oil will not provide the environment the accumulation of carbon dioxide in the atmosphere , and that Yan production of 20 kWh of electricity in a power plant produces 120 grams of carbon tog carbon per kilometer driven car. So it is the interest of the environment to be the production of electricity -free way of generating carbon dioxide. Any sustainable energy and nuclear energy .Policy to reduce consumptionThe European Union recently decided to reduce the consumption of gasoline cars and diesel until 2020, so that no more than 95 grams of carbon dioxide per kilometer , which means consumption of 4 liters of fuel per 100 kilometers . The companies operate auto production in Europe to develop engines and access to that extent also with the help of hybrid cars because of the difficulty of reaching that limit by reducing the consumption of the engines alone . European policy has decided to take this approach to reduce releases of carbon dioxide for cars . Believed that the United States and China will Taatavan this way in the future . It will be a leading European car companies in that regard .Has been able to auto companies in Europe to reduce the consumption of cars between 1995 and 2008 by 25%.

Collision in TokyoPassenger vehicle safety depends on your driving style to motorists as well as to follow the traffic system . The systems include instructions on traffic to pass , and the development and traffic signs , banners, and follow the instructions of the importance of the use of safety belts , and to refrain from using the phone while driving . The invention and development of Anakll , divided and safety features in modern vehicles into two types: first , means of security at reducing the consequences of an accident can not be avoided. It means that the presence of seat belts in the car and Iahbma for all passengers. And the presence of head restraints and airbags , steering wheel and be flexible so as not to be a cause of excess hardness injury , and that the design of the front of the car so that it contains space bear without the crush of the crush size up to the passenger compartment . As well as provide modern vehicles cushioned side airbags are working on prevention of Astdamat passenger side . It modern technologySecondly, the supply of modern cars means design can be said as an active working to reduce the likelihood Astdam and be of help to the driver of the car to avoid Astdam , including the system of ballasts anti- skid ABS, and guidance systems modern electronic called ESP works to balance vehicle during critical situations .Then should be noted the role of the driver of the car and taken into account the importance of the road conditions and others . Attention must be paid , as well as educating children and young people with traffic regulations , and urged them to follow.Have helped those means in a country like Germany , for example, to reduce the number of road accidents than 60,000 fatal accident in 1971, about 21,000 L. accident in 2004 .Showing some electric carsToyota RAV4 EV battery works with 24 of each 12-volt , 2005 .Electric car a range of 80 kilometers.CarHoliday TrafficCrowded roads in the maximum hours of traffic with cars and buses and vans , which wasted on people and the nation so much time and cost may be prohibitive in excess consumption of fuel and absence from work . In the United States , for example, the average holiday that is exposed driver of the car about 35 hours per year . It is estimated for a large country like the United States of America in the amount of pointless Total estimated U.S. $ 100 billion . Show statistical conducted by TTI that every motorist in the United States bear Expenditure on holiday because of the traffic is estimated at 713 dollars a year , an amount sufficient to perform maintenance on his car every year . The most crowded cities in the United States : Houston , New York , Washington and Chicago and Salt Lake City , and Detroit .The nation's largest producer of carsShow statistical brought about by the magazine " er de ACM " (2) the future of the production of the country's major car and Tha show that China began in 1977 to produce cars and was Atnajitha which has about 200 private car , and increased productivity at an amazing speed until it reached 14 million cars in 2010 . It also shows the evolution of statistical production cars in the top countries of the list , as follows:• China : 200 vehicles in 1970-14 million vehicles in 2010 .• Japan : 3 million cars in 1970-8 million vehicles in 2010 .• Germany : 5 and 3 million in 1970-5 and 5 million cars in 2010 .• South Korea: one million cars in 1980-3 million vehicles in 2010 .• Brazil : 100 thousand cars in 1970-5 and 2 million cars in 2010 .• India : 100 thousand cars in 1980-5 and 2 million cars in 2010 .• United States : 6 million cars in 1970-5 and 2 million cars in 2010 .• France : 3 and 2 million cars in 1970-2 million vehicles in 2010 .• Spain : 3 and 0 million cars in 1970-8 and one million cars in 2010 .• Mexico : 100 thousand cars in 1970-3 and one million cars in 2010 .And observed a significant decline in the productivity of the United States from six million vehicles in 1977 to 5 and 2 million cars in 2010 .
