Regardless of what type of vehicle you drive, if it was built in the last few decades, its engine has some form of emissions control system designed to reduce the harmful environmental impacts of ...

The internal combustion engine, despite being a century-and-a-half old, is still an impressive marvel of engineering. There are several variations of engine design that have been experimented with ...

This is a category that is pretty rapidly going away. You'll be hard-pressed to find an overhead valve — also known as a pushrod — engine in anything outside of a General Motors LS/LT V8 or one of ...
