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 ...

Modern engine bays are filled with black plastic where bright cast aluminum once sat, and few parts symbolize that shift more ...

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 ...

While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...

OHV stands for overhead valve, and these types of powerplants can also be called pushrod engines. OHV engines have the intake and exhaust valves located above the camshaft, which is in the engine ...

We reached out to CEO and Co-Founder, Landon Wilkinson, to see where things stand in June 2024. "The revised engine design is coming along nicely," replied Wilkinson. "We achieved positive compression ...

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 ...
