General Motors, founded by William C. Durant on September 16, 1908, was first major automobile company to compete with Henry Ford. General Motors started as only the Buick Motor Company, however through the years, William C. Durant acquired many other companies. It was General Motors that actually took the automotive industry to a massive scale, controlling more than 20 companies such as Chevrolet, Buick, and Pontiac. In the late 1920’s GM made vehicles that were slightly more efficient than Ford and later GM’s sales surpassed Ford’s. In the 1930’s General Motors created the first diesel powered trains, with soon sparked the idea of diesel powered automobiles. With this diesel breakthrough, cars started getting bigger, faster, and much more powerful than they were with original gasoline engines. With this, people realized that automobiles did not have to be in only one shape or form and many other companies were born.
The last of the big 3 companies was Chrysler. Founded by Walter Chrysler on June 6th 1925, the Chrysler company was the first car company to manufacture parts that are seen in vehicles today. A carburetor air filter, high compression engine, full pressure lubrication, and an oil filter were first invented by Chrysler, features that were absent from many of the automobiles of that time. Chrysler was the first automotive company to actually take the automobile and make …show more content…
The combustion process consists of four steps. The four steps is what allows heat to be transferred into usable mechanical energy. The 4 steps are also called “strokes” thus the phrase “four stroke engine.” The first stroke is called the intake or suction stroke. During this step, the intake valve opens allowing air and fuel mist to enter into the combustion chamber. The volume of the combustion chamber increases, thus pushing the piston down. The next stroke is called the compression stroke. In the previous step the piston was pushed down due to the volume of the combustion chamber increasing. During the compression stroke however, the opposite happens. Just like the name suggests, the piston works its way back up and compresses the fuel air mixture. Just before the piston compresses the air fuel mixture to its maximum potential, a spark plug, which is located at the top of the combustion chamber, ignites the air fuel mixture. That leads to the third stroke, called the power stroke. After the fuel ignites, it pushes the piston down with extraordinary force. As the piston moves downward, it turns an array of gears which then turn the wheels of the automobile. It is the power stroke that converts heat energy into usable mechanical energy. The final stroke is called the exhaust stroke. After the fuel is burned, there are used chemicals inside the combustion chamber. In order for the chemicals
