The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

Taking an engine compression test is sort of like checking your car's blood pressure. It's a quick and painless procedure that can reveal hidden issues.

Last month we acquainted you with a few unique procedures for using conventional tune-up devices—such as a vacuum gauge, timing light and electrical analyzer—for evaluating the efficiency and ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

Test compression sounds like magic. Read on to learn how this trick is done. Large, complex ICs are viable because their design meets test as well as functional requirements. Design for test (DFT) was ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...

Test compression technology was invented to address the problem of escalating test-pattern size. Compression allows more test vectors to be applied to an IC in a shorter time and with fewer tester ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...
