Unfortunately, no matter how careful you are behind the wheel, accidents happen. The good news is, dash cams have become much ...

In almost every segment of engineering, Moore's Law has ushered in new eras of programming, and electronic camming is no exception. Cam operation is a mode in which controls follow a cam profile ...

Beyond cam profile improvements, there is variable valve timing. Used stock on some late-model engines, it's most commonly implemented as a way to automatically ad-vance and retard the camshaft ...
