How Automotive Temperature Gauges Work
We rely on a temperature gauge to tell us the conditions inside the engine's cooling system. The gauge typically sit in the car's dash and never needs maintenance. How's that happen?…keep reading
How Light Bulbs Work
While light bulbs might seem trivial, simple things to talk about, relatively few people really know the complex physics process that takes place when a lamp turns on. These commonplace items haven't significantly changed since the days of Thomas Edison, but they are nonetheless marvels of science. We thought it appropriate to explain this process in a little detail…keep reading
Combustion Chambers (and a little engine theory)
The combustion chamber is the area inside the engine where the fuel/air mixture is compressed and then ignited. This article discusses some of the combustion chamber designs that greatly effect your engines efficiency…keep reading
Tachometers have been around for a long time. Devices to count revolutions were used on water wheels, steam engines and many other rotating machinery devices for the purpose of maintaining safe speeds…keep reading
Body Filler - What Is It?
Ever wonder what Bondo (the body filler brand name turned generic), is made of and how it works? We did a little investigating into its makeup, and here's what we found…keep reading
The first cars that first started using catalytic converters are now 30 years old, making them easy candidates for "antique" or "collector car" status. Since some of us are now - or will be shortly - collecting these vehicles it's high time we explain how the converters work…keep reading
