Cars

Cars are automobiles that can transport people. It is the chief means of travelling for hundreds of millions of people all over the universe. Cars have changed the way we live credibly more than any other invention in history. At first only a few people had cars but after a while more and more people bought them because they improved the manner people lived. Farmers with cars were able to bring their products to places that were further away. The appearance of cities and towns besides changed. More and more workers drove to their jobs and people started to move to suburbs outside the township centers .
Automobiles give people many jobs. Millions of people around the earth work in factories where cars are produced. Millions more workplace at natural gas stations, restaurants or motels that travelers stop at.

however, cars besides cause problems. Millions of people die in car accidents every year. Automobiles pollute the air that we breathe and parking space in cities is scarce because everyone wants to use their cars to get to city centers .

How cars work

Cars are very complicated machines and all systems in them work together. They power a cable car, control and steer it and make it comfortable for people to drive in .

The engine

The heart of every car is its engine. It produces the power that turns the wheels and electricity for lights and other systems .
Most automobiles are powered by an internal combustion engine. Fuel, normally gasoline or gasoline, is burned with air to create gases that expand. A spark plug creates a spark that ignites the gasoline and makes it burn. This energy moves through cylinders in which pistons slide up and down. They are attached to rods that move a crankshaft. normal car engines have four to six cylinders but there are besides models with eight and sixteen cylinders. The turning movement is passed through the drivetrain to the drive wheels .

Fuel system

The fuel arrangement pumps gasoline from the cooler to the locomotive. Older cars used to have carburetors that mix fuel with air and send the flatulence to the engine. Some cars have a special fuel injection system that sprays gasoline into the engine. modern cars have turbo chargers that suck in excess atmosphere and therefore make more exponent .

Drivetrain

The engine and all parts that carry might to the wheels are called the drivetrain. It includes the transmission, drive shaft, differential, the axles and the drive wheels that move the cable car. While most cars have drive wheels in the front, some have them in the back. Cars that need to drive over all kinds of crunch have a four-wheel drive .
The transmission controls the focal ratio and torque. When a car travels at a normal speed on a apartment road it does not need so a lot torque to keep it moving, but when you want to start a car from a mound the engine must produce more office. Gears control amphetamine and power of the engine in different drive conditions .
In cars with manual transmission you have to change gears by pressing down the clutch with your foot and moving a lever. Cars with automatic transmission change gears without control by the driver. Lower gears give the car more torque and focal ratio. When the car moves fast the transmission shifts to higher gears .
The driveshaft carries the office to the axle which is connected to the wheels. It has respective joints which make the axle and wheels moveable as the cable car drives on uneven and bumpy roads .
The differential is connected to the rear end of the driveshaft. It lets the wheels turn at different speeds because in curves the outer wheels must travel a greater distance than the inner ones .

Steering system of an automobileSteering system

The steering system controls the front wheels. Turning the steering bicycle makes them point to the left or proper. Most cars have power guide ; a hydraulic system makes it easier for the driver to turn the wheels .

Brake system

The brake system slows down or stops the cable car. Brakes manoeuver on all four wheels. There are two basic types of brakes : drum or disc brakes. In both cases a friction pad is pressed against a drum or disc with the help of a hydraulic system .
All cars have emergency hand brakes which you use if the hydraulic system fails. It is besides called a parking bracken because you use it to stop a vehicle from rolling down a mound. Antilock braking systems ( ABS ) keep the wheels turning when you step on the brakes. This computer controlled system prevents skidding if you are on a slippery road

 

Suspension system

The suspension system supports the weight of the car. It has wheels, axles, tires and springs. Most cars have shock absorbers to guarantee a smooth drive. Springs are between the axles of the wheels and the body of the car. They allow each wheel to move up and down on its own. The tires besides help to make drive smoother. They are built so that they give the cable car grip on roads in all conditions .

Exhaust system

When a car burns fuel gases are produced. They must be removed so that new fuel can be burned. The pistons in the locomotive ’ s cylinders force gasoline out of the locomotive. It passes through a muffler into tail pipes. The muffler besides keeps the car running quietly. For about thirty years cars have been equipped with a catalytic converter. It reduces pollution by converting harmful gases into carbon dioxide and urine

Cooling system

Burning fuel inside a car ’ south engine creates a distribute of heat. Most of it has to be removed by a cool system. Liquid cooling systems have a concoction of water and chemicals. A urine pump forces this concoction to flow between the cylinders of the locomotive. The blistering water is then pumped through a radiator where the air carries away the heat .

Lubrication system

Oil is crucial for an engine to work. It flows through the moving parts so that the metallic element does not rub against other metallic pieces. Without lubrication the metallic would become besides hot and the engine would be destroyed .
oil is stored in an oil tank at the bottomland of the engine. From there it is pumped around the engine. A filter removes dirt from the petroleum so that it won ’ t do any damage to engine parts. After you have driven a certain number of kilometers you must change the petroleum and the oil trickle .

Dashboard

The dashboard has many instruments that show you how fast you are moving, the amount of gasoline that is left in the tank car, the anoint temperature and some other information .

Body

The soundbox of the car is the out shell that surrounds the mechanical parts and the passengers inside. Most bodies are made of steel, although some parts are made of potent plastic or fiberglass. The soundbox includes the passenger compartment, hood, trunk and the fenders which cover the wheels .

Types of cars

  • Coupe = a two-door car with a fixed roof and a smaller back seat.
  • Convertible = a car with a flexible roof that can be folded together, so that you can drive without it
  • Station wagon or estate car = longer vehicles for larger families ; most of the time they have an extended cargo area
  • Sedan = common car type with two rows of seats and four doors. The car has a separate boot (trunk) for luggage
  • Minivan = a taller car that is shaped like a van; it has up to three rows and can carry 8 or 9 people.
  • Sport utility vehicle (SUV) = built like a small truck, it has a four wheel drive and space like a minivan ; it is often an off-road vehicle made for travelling on rough ground
  • Sports car = low to the ground with only two seats and a powerful engine

Safety features

today all cars have safety features that protect passengers from accidents that may happen on the road. In about every country passengers have to fasten their seat belts. Children and babies must be put in particular seats .
Since the mid 1990s about all cars have been equipped with vent bags. They are normally in the steering bicycle and if a car crashes they come out, inflate and protect the passengers from slamming into the front window. But there are other safety laws that carmakers must follow. Doors must have extra locks that are crash resistant and bumpers must be able to absorb some force if the car crashes .

History of cars

In the late 1770s Nicolas-Joseph Cugnot, a french engineer, built a car that ran on steam. many american companies besides started producing them but they were identical expensive to make and cost a lot of money .
As clock went on, engineers started experimenting with petrol-driven cars. They could travel faster and over longer distances. They were besides safer than steam-powered models which ran with gasoline
Towards the end of the 19 thorium century Germany became the center of car-making. Nikolaus Otto built the beginning internal combustion engine, Gottlieb Daimler and Karl Benz besides began building petrol-driven engines .

automobile production in the USA began in the 1890s. It was Henry Ford who started producing cars on an assembly line. Workers do only one task and car parts pass on a conveyer swath. By 1908 Ford ’ s Model T became the most popular car in the world and by 1927 the Ford Motor Company had produced over 15 million of them .
After cable car production had slowed down during the two global wars car makers began adding new features to post – war models. Power steer, office brakes and automatic controls became common. More and more bad cars were produced in the 1950s and 1960s. They used up a lot of fuel in a time in which oil was silent identical brassy .
This changed in the 1970s when arab oil-producing countries started to raise prices for vegetable oil because westerly countries supported Israel. In the years that followed a lot was done to try to save and conserve fuel. Automakers started producing compress cars that were fuel-efficient.

In the meantime, Japan and Europe had begun to compete with american carmakers. By 1980 Japan became the largest car producing countries in the world .

The car of the future

Even though nowadays ’ mho cable car is a great machine that is firm, elegant and beautiful to look at, engineers are constantly working on a car that will make nowadays ’ second automobile look old. Experts say that future cars will be made of plastics and carbon fibers that will be stronger and lighter than steel .
As oil is becoming more and more expensive, alternative power sources are being explored. Biodiesel, hydrogen fuel cells, electric cars and hybrids are department of energy sources that carmakers may use in the future .
Cars are becoming cybernate machines. Some sidereal day they may drive themselves. Highways and other roads could be built so that cars can be programmed to drive along them by automatic pilot while passengers sit in the back and relax. such cars could be radar controlled to avoid contact with other vehicles on the road .
