In simple terms, a crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached. It is a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocationg motion of the piston into rotational motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or "crankpins"- additional...

All-Wheel Drive
Four-wheel drive, 4WD, 4x4 ("four by four"), or AWD ("all-wheel drive") is a four-wheeled vehicle with a drivetrain that allows all four wheels to receive torque from the engine simultaneously. While many people associate the term with off-road vehicles and sport utility vehicles, powering all four wheels provides better control in normal road cars on many surfaces, and is an important part in the sport of rallying. The first application of four-wheel drive, occurred in 1893. In 1937, the...

FeaturedLeasing vs. Buying
How does the cost of leasing a Challenger compare to buying it, in terms of out-of-pocket costs? Or if you decide to buy a used Challenger, how much more will you save? And finally, what do those costs look like in the long run? These are important questions for buyers who want to carefully manage their automotive expenses over the years. It's hard to give one answer that covers all people and all situations. But the question can be divided into two parts: 1. An analysis of the hard costs...

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...

Shock Absorbers
An automobile shock absorber is basically a hydraulic piston that absorbs and dissipates vibration using spring-loaded check valves and orifices to control the flow of oil. The first production hydraulic dampers, to act on the main leaf spring movement, were probably those based on an original 1908 concept by Maurice Houdaille. One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the...
