Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

Contemplating the advantages of the pushrod-actuated overhead valve engine design in what appears to be the twilight of internal combustion might sound as anachronistic as a quick look at the value of ...

Researchers at Purdue University's College of Engineering are conducting tests on a patented Tesla valve-inspired injection manifold design to improve the efficiency of rotating detonation engines ...

The intricacies of airflow dynamics through a cylinder head are some of the most difficult concepts to grasp in all of hot rodding. That made it the perfect topic to discuss in the inaugural ...

Michael Arsenaeu designed the Avadi engine 20 years ago in the hopes of creating an entirely new engine design to be efficient as well as reduce emissions. In 2015, Avadi began the build and ...

The Buick Division of General Motors never had it so good. After hammering at the door of the “Big Three” for 17 years, the door suddenly opened and even Buick personnel were amazed to find that their ...
