HISTORY OF CAR

Many people thought of making a self-propelled vehicle centuries before the car was invented. A major problem was finding a was to make it move. Some inventors tried to wind power, but they didn't have very much success. What they needed was an engine.

After the steam boat was invented in the 1800's, steam-powered vehicles were being built by engineers. A steam engine had to be big and heavy enough if capable of producing enough power to move the vehicle.

Engineers started building their own cars in the United States and in Europe. Without horses, cars started to look more like modern day cars. Cars were ready to rule the world at the end of the nineteenth century.At first people could only buy cars that were built by skilled people. Only rich people could afford them because they were very nice and fancy. Most people only wanted to look at the car, not buy it.

To day we power vehicles by diesel. At the beginning of the century, engines ran on steam, gasoline, kerosene, oil, and electricity. In places were coal was cheap, trucks that ran off of steam were popular. for deliveries in towns and cities, electricity was perfect.Reliability was a problem with internal combustion. The firms wanted to use horse and steam engines because they were more reliable than internal combustion.

After World War I, army trucks were sold to buyers to use as road transportation. As loads got bigger, pneumatic tires damaged the soft-surfaced roads. Two extra wheels in front for steering and four in the back to spread the weight were usual to see.
