A remote starter switch and a top-quality, screw-in-type compression gaugeâ such as these models from Sears, Roebuck & Companyâ can be used to measure the pumping efficiency of an engine, as well as ...

In this first of two articles on engine mechanical testing, we will introduce two fundamental engine mechanical tests that will be performed with electronic tools. This first test is the relative ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

At least 150hp of a Pro Stock engine is due to the use of ultra high compression ratios (CR) of 16:1--or more. 110 octane race fuels make this possible, but don't be fooled into thinking that the use ...

I got a message last week from my friend Craig Fitzgerald, asking for help with his 1965 Corvair Monza. As president of the New England Motor Press Association and editor-in-chief at BestRide.com, ...

Abstract: In this paper a theory of cylinder elastic-plastic formation in materials with difficult tension and compression modulus is presented. Based on elastic theory with different modulus in ...
