Essay About Cars Advantages

In the beginning of human life, many devices are invented by human. The most important of these devices undoubted is fire and the second one is wheels. Invention of wheels was created a way for produce the first car. I do not have enough information that when and where the first car is produced, but I believe its inventor is was a genius.

In modern world, we cannot imagine a life without cars. In some ways, our life depended on cars. Cars have a lot of disadvantages and disadvantages, I consider some of them. The first advantage is our life become well. In the past, people do not have car, they used to animals for journey or traveling. Using of animal had some limitation, if we wanted to go some city; they would in way for more than two days.

Secondly, cars are very fast and comfortable. We can use air condition for having fresh air. Cars are made in many sizes and for many purposes. We have sport cars, ambulances, Police cars, buses and so on. All of these types have significant role in human life.

On the other hands, there are some disadvantages. Having a car is costly. Car is not a cheap device; we have to pay more money to buy one of them. In addition, we must buy other thing such as fossil fuel, antifreeze, new wheels for our car. Also sometimes, our car stops working, so we need a mechanic to repair it. All of these issues need money. The worst part is fossil fuel. Increasing of number cars in our street and all of them using fossil fuel. Consequently, our climate becomes more and more pollute.

To sum up, although, car has disadvantages; we cannot stop using of them. We can just try to improve them, find green fuel and using it instead of harmful fuel.

A car is a road vehicle used to carry passengers. It is also called an automobile, which comes from the Greek word "auto" and the French word "mobile". This name means "self-moving", as cars do not need horses or other external sources of power to move. Cars usually have four wheels and get their power from an engine, though many new cars made today do not have engines. Millions of cars were made during the 20th century.

Technology[change | change source]

Like other vehicles, cars are made in different shapes and sizes, for people with different needs. Some small "city" cars carry only two to four people, with only small space for luggage. Other types are able to carry many passengers or heavy loads. For example, station wagons or estate cars carry from 5 to 9 people, or fewer people with lots of luggage. There are many different sizes of vans, such as minivans, which are made for families, and even small pickup trucks, which are car-like vehicles made for carrying medium-sized loads; for example, goods for delivery or plumber's and builder's tools and materials. Heavy lorries are used to carry deliveries and heavy loads.

In order for a car to work, it must have a power source, where the car gets the energy it needs to turn the wheels. Most cars use some kind of fuel to make an internal combustion engine run. The power from the engine then goes to the wheels through a transmission, which has a set of gears that makes the car go faster or slower. The most common fuel in small to medium-size cars is petrol, which is called gasoline in America (people just call it "gas" though). Some larger, more expensive cars burn diesel fuel, which is used in big trucks and buses, and a few use wood gas. In some countries, such as Brazil and Sweden, a mixture of ethanol and petrol, called gasohol in Brazil and E-85 in Sweden, is used as automobile fuel. There are cars designed to run on more than one type of fuel - these are called "flex-fuel" and are very rare.

Alternative fuel cars[change | change source]

All of these types of fuel are called fossil fuels because they come from fossils that were made millions of years ago. Over time, they turn into oil, which is then drilled up from deep inside the Earth, and then turned into fuel by chemical changes. Because there are so many cars around us today, there will be one day when there is no more oil left in the ground. When that happens, we will not be able to make any more fuel to run our cars. This is why fossil fuels are non-renewable resources. Also, burning fuel in an engine produces a lot of exhaust, which can go up into the atmosphere and cause global warming. This is also going to be a problem in the coming years.

To solve these problems, scientists and engineers are coming up with alternative fuel vehicles, which use fuels that are less common, but are renewable and will never run out. They include propane, natural gas, compressed air, and ethanol (which comes from plants). More recently, there are cars that run on electricity. These can come in different types. They may store electricity in a battery (as in the Nissan Leaf), or generate it from hydrogenfuel cells (like the Honda Clarity). The electricity then drives an electric motor instead of an engine, which then turns the wheels. These cars are much quieter than other cars and do not give out any polluting exhaust gasses (although some ecologists say that most of the hydrogen that people use comes from burning fossil fuels). Cars that use batteries can be recharged in different ways, usually from a power outlet, but some even use solar cells. There is a competition every year where people try to design a car that can last the longest and go the farthest on solar energy alone.

There is also a type of car that uses both an internal combustion engine and an electric motor. This is called a hybrid electric vehicle and an example is the Toyota Prius.

History[change | change source]

The earliest automobiles recorded were actually steam engines attached to wagons in the late 18th century. The steam engines were heavy and therefore the wagon was slow and hard to control. Better and faster steam cars became common late in the 19th century.

Some cars in the early 20th century were powered by electricity. They were slow and heavy and went out of use until the idea came back later in the century.

The internal combustion engine changed the way automobiles were powered. The engine used either gasoline, diesel, or kerosene to work. When the gas is exploded in a cylinder it pushes the piston down and turns the wheel.

Although many people tried to make a good car that would work well and sell well, people say that Karl Benz invented the modern automobile. He used a four-stroke type of internal combustion engine to power his Benz Patent-Motorwagen. In 1886. He began to make many cars in a factory and sell them in Germany in 1888.

In North America, the first modern car was made by the Duryea Brothers in Springfield, Massachusetts. The Duryea Brothers' car also won the first-ever car race in 1895, competing against cars made by Benz. The race was in Chicago, Illinois, and 53 miles long. Duryea then began making the first automobiles for everyday people to use in 1896. That year they made 13 cars by hand in Springfield, Massachusetts.

Benz may have invented the first modern car, and Duryea the first car to sell, but Henry Ford sold the most cars to the most people. In 1910 he began making and selling his Model T, which was a huge success. Many people could afford this car, not just the rich, because Ford used mass production. This meant he made a great many Model Ts in a short time in a factory. People say that the Model T is the car that "put America on wheels". The Model T was the most popular car of the time because it was cheap but it was still a good quality car that ordinary people could own.

Since then, many different kinds of cars have been designed and built, from minivans to sports cars.

In the 1950s the United States made and used more cars than all the rest of the world. The world caught up, and fifty years later China became the largest maker and user.

Advantages[change | change source]

Cars are faster than walking or riding a bike if you are going a long way. They can carry more than one person and a large amount of luggage. Depending on local public transport quality, they can also be faster and far more convenient than using buses, bicycles or trains, and can often go where public transport cannot. 4-wheel drive "off road" vehicles are particularly good at reaching places difficult for other wheeled transport due to bad roads or harsh terrain. They cost more and burn more fuel, and there are many places even they cannot go.

Most cars enclose people and cargo in a steel cage, (having a roof, doors and windows), thus giving protection from weather. Modern cars give further protection in case of road accident, as they have added safety features such as seat belts, airbags, crumple zones and side-impact protection that would be expensive or impossible on two-wheeled or light 3-wheeled vehicles, or most buses.

With regular check ups and car servicing, cars can last a very long time. In some countries like Australia, you have to get your car checked by authorised mechanics regularly by law to confirm that your car is safe to drive. You can go into a car mechanic to get your car checked or have a mobile mechanic come to you to repair your car.

Disadvantages[change | change source]

Buying and running a car needs a lot of money, even more for a good quality one that is not too old. There are things to pay for - the car itself, fuel, parts (for example, tires/tyres), maintenance, repairs, insurance to cover the cost of crashes or theft, parking charges, and toll roads and any tax or licensing fees charged by government.

When cars crash they can be damaged and hurt people, and life of a person is more important. When too many cars try to go the same way, traffic congestion slows them all. They can cause air pollution if too many are used in a small area like a city, and the combined pollution of the world's cars is thought to be partly to blame for climate change. Many places where people live close together have public transportation (or mass transit) such as buses, trains, trams and subways. These can help people go more quickly and cheaply than by car when traffic jams are a problem. Some of these problems can be made smaller, for example by carpooling, which is putting many people together in one car.

Traffic congestion and accidents can be dangerous to other road users, for example people riding bicycles or walking, especially in an old town built when cars were few. Some 20th century towns are designed for cars as the main transport. This can cause other problems, such as even more pollution and traffic, as everyone has to drive. Communities are divided up and separated with big roads. Pedestrians are in danger where there are too few foot bridges, small road bridges or other crossings.
