A crash test dummy is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers,automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data, such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision....

Evolution of Rear Spoilers
A car spoiler is a stylish automobile accessory that can be mounted on the rear of most cars. There are many different styles of spoilers. The general shape consists of a slender slightly downward angled piece of metal, fiberglass, silicone or carbon fiber that is usually the width of the vehicle. Some seem to appear to mold into the vehicle and others stick out with two small ledges on both sides. The term "spoiler" is often mistakenly used interchangeably with "wing." An automotive wing...

Ignition Coils
An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system. It transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. Early gasoline internal combustion engines used a magneto ignition system, since vehicles did not have batteries. The voltage produced by a magneto was dependent on the speed of the engine, making starting difficult. A battery-operated coil, however,...

The Meaning of "Mopar"
Short for the Chrysler Motor Parts Corporation, Mopar made its first appearance in the late 1920s and became its own brand in 1937. The name Mopar was created by a committee to market cans of "Chrysler Motor Parts" antifreeze. From there, the Mopar catalog expanded to include waxes, cleaners, filters, engine parts and more. Now, in its 81st year, Mopar encompasses the full line of Fiat Chrysler Automobiles parts, accessories, and customer service, including Fiat and Alfa Romeo brands...

Evolution of Hood Scoops
Back in middle school science class, we learned that in order to make fire, you need three ingredients: fuel, ignition and air- or, more specifically, oxygen. You’ll also remember that cold air is denser than hot air, putting more oxygen in the same amount of volume. While the modern internal combustion engine does a fine job of delivering fuel and ignition, that cold air part becomes tricky as you try to route fresh air from outside through a hot engine compartment. In response, in the late...
