An interesting patent has been filed by Toyota for an engine with variable compression. The patent is for an engine with variable length connecting rods. The connecting rod features two hydraulic ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

Examination then determines compression efficiency, compression rod loading, tensional rod loading, wrist-pin reversal, minimum volumetric efficiency, and brake-horsepower. Checking these data points ...

Utah's Transcend Energy Group claims it has a relatively simple and cheap way to dramatically increase the torque output of combustion engines, simply by replacing the standard connecting rods with ...

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