 Theory and Design of Automotive Engine




Automobiles through the Years - Since they originated in the late 1800s, automobiles have changed and developed in response to consumer wishes, economic conditions, and advancing technology. The first gas-powered vehicles looked like horse buggies with engines mounted underneath because this was the style to which people were accustomed. By 1910, however, features like the front- mounted engine were already established, giving the automobile a look that was all its own. 

As public demand for cars increased, the vehicles became more stylized. The classic cars of the 1920s and 1930s epitomize the sleek, individually designed luxury cars called the “classic cars.” During the 1940s and 1950s, automobiles generally became larger until the advent of the “compact” car, which immediately
became a popular alternative. The gasoline crisis is reflected in the fuel efficient cars made in the 1970s and 1980s. Current designs continue to reflect economy awareness, although many different markets exist.

The history of the automobile actually began about 4,000 years ago when the first wheel was used for transportation in India.
In the early 15th century the Portuguese arrived in China and the interaction of the two cultures led to a variety of new technologies, including the creation of a wheel that turned under its own power.

By the 1600s small steam-powered engine models had been developed, but it was another century before a full-sized engine-powered vehicle was created.
In 1769 French Army officer Captain Nicolas-Joseph Cugnot built what has been called the first automobile. Cugnot’s three-wheeled, steam-powered vehicle carried four persons. Designed to move artillery pieces, it had a top speed of a little more than 3.2 km/h (2 mph) and had to stop every 20 minutes to build up a fresh head of steam.
