my work deals with

automobile

From its origins until

now

could you imagine your life without a car?

• the definition of car is as follows: vehicle with four-wheel motor used specifically for the transport of persons.

• This definition is current for that before the vehicles were so...

• I'm going to explain how they work and their origins

Its beginnings…

• It is believed that the beginnings were in China at the end of the am 17.

• But in 1769 was when the writing and inventor Nicolas Cugnot Josep presented the first steam-powered vehicle.

• It was a tricycle of 4.5 tons with wooden wheels and rims of iron.

Its beginnings…

• The automobile as we know it today was invented in Germany in 1886 by Carl Benz.

• The first trip was made by Betha Benz in 1888, It was Mamnheim and Pforzheim cities separated by 105 kilometers.

• Auto alter not only the way of living cities and the landscape, but it became the industrial product.

Its beginnings…

• first it was invented to steam.

• Richard Trevithick improved design, registered compact engines on wheels, referred to as devil Resoplante.

• Later it was coal gas engine invented by Jean Josep

• Nikolaus August Otto invented and then patented a four stroke engine, known as the "Otto circuit".

• 1886: The engine was moving.The first vehicles using internal combustion engines were developed by two engineers, more or less during the same dates, in two parts separated from Germany; These were Gottlieb Daimler and Karl Benz.

Its beginnings…

• 1894: The Grand Prix races begin.Racing began as soon as built were cars. Races soon evolved from small persecutions from village to village, to events organized as endurance time for cars and drivers.

• 1896-First victim of trafficking.Bridget Driscoll, a mother of 44 years of Croydon, came out fired direct sidewalk to the history books. It was rolled by a car passing near the Crystal Palace in London. He died of wounds in the head.

• The driver, Arthur Edsell, was only 6 km/h at that time. Coroner, who gave a verdict of accidental death, said: "I trust that this kind of nonsense doesn't happen anymore".

Its beginnings…• 1903 – The Ford car company is formed.

• After establishing mobile assembly lines at the factory, in 1913, Ford became the largest manufacturer of cars in the world.

• For 1927, 15 million model T Ford, had been manufactured. The workers on the production line, joining the car in only ninety -three minutes.

• 1911: Key development.

• Charles Kettering invented electric ignition engine while working for the Department of design and development of the Cadillac. Now the car could start automatically.

• Kettering then introduced the independent suspension, and four-wheel brakes. By 1930, most of the technology used in automobiles today, had already been invented

• 1978: Decreases the distance to stop safely.

• The first set of brakes anti-lock (ABS, according to its acronym in English) was developed for automobiles by the German manufacturer Bosch. They appeared first in trucks and cars made by Mercedes-Benz.

• ABS brakes allow the driver to maintain control of the direction and reduce the distances when braking.

• 1997 - The auto manufacturers become eco-friendly.Manufacturers are aware that oil reserves will run their course in the future. This is the reason why you are developing engines that use more than one source of fuel: hybrid engines.The Honda and Toyota introduced initially in the Japanese market their hybrid of gasoline and electricity, before launching them in America and Europe in the 20

what materials does it take a car?

• Those times in which the iron and wood were the predominant materials in the construction of a car have gone down in history. Now we talk about magnesium, aluminum, or fibers of carbon.

• One of the main objectives of the automobile industry is to reduce the weight of the components (thus consumption slows and the benefits are improved - on occasions -). For this reason, they have turned in the development of different alloys of aluminium and plastics

• The last known in "materials policy" bet comes from the BMW with its 6 series. This vehicle combines different components with the aim of reducing the weight of the body. Under the slogan "intelligent use of lightweight materials", the engineers of the German company have prepared a body made of steel, aluminium and plastic materials. This mixture reduces the weight of 20 per cent on the front, with respect to the weight of this piece in conventional steel. But there not just innovations. The place in which is based the suspension and damping is an alloy of aluminum, magnesium, silicon and manganese. Results? Ten

• Cars most old (and material more rigid) suffered some minor impacts, but are massacred before a severe shock. Besides its resistance was uniform. The more new material you use more lightweight and flexible. lightness helps that inertia is not so strong in a serious crash, and the flexibility helps not to create sharp edges that are you can nail. But change is dents easily with mild shock.

Things that cannot be made while at the wheel

• We should not talk on the phone: there are devices like handsfree or bluetooth, which allow a minor distraction when talking on the phone.

• We must respect the other drivers.

• We must not eat while we drive, we could cause risk of accidents.

• We must not listen to very loud music.

• We must have patience when there is traffic.

• We must not slow down abruptly.

• We must take the safety belt.

• We must bring the necessary documentation.

• We must wear sunglasses when the sun didn't bother to view.

• We can not drink when we drive.

• we have to stop when the police like that indicate it

• We can not pass the limits of speed

• If we have children we have to carry on your approved Chair

• can not release anything for windows

• You must park in enabled areas, otherwise you will put a penalty

• You have to respect the traffic signals

BAD GOOD

• For three centuries the engines have been the ultimate expression of the quest for technical excellence. Modern gas engine was invented in 1860, but it was not until Nikolaus August Otto who in 1876 built the first four-stroke gasoline engine. A 1997 report had 600 million the number of vehicles of humanity.

An internal combustion engine is a thermodynamic machine that transforms chemical energy provided by the combustion of a mixture of air and fuel into mechanical energy. This movement is used to stop performing useful work. There is nothing better than a video * to understand the operation of a gasoline engine.

• The rotary movement of the engine comes from a reciprocating motion and a series of perfectly synchronized actions. Four times or stages are called intake, compression, explosion and exhaust. First opens the inlet valve and the mixture of air and gasoline enter until you reach the maximum volume or bottom dead center, then compresses the mixture up to what is called the upper dead point. At this point there is combustion of the mix, thanks to the spark from the spark plug, causing the expansion and moves the piston down producing work. Finally the outlet valve is opened and is

expulsan of combsution gas.
