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 ...

A small gap with big importance in the performance and health of an engine - here's everything you need to know.

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 ...

I’m not sure if any engine built today will still be salvageable 100 years from now. Not to sound like a grump, but so much relies on computers that will surely be obsolete by then. And let’s not get ...

Q:I have a 327 in my '31 Ford that features nearly the same cam and components as the one you referenced recently in Pit Stop (Nov. '12). Since a 1.6:1-ratio rocker arm will push the valve a little ...

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 ...

Even as EVs begin to encroach on ICE cars, the development of fuel-burning engines hasn't stopped. With almost 150 years of development in the Otto cycle internal combustion engine, you may think ...

Part 2 Of Our Cylinder Head Roundtable. Our All-Star Cast Of Experts Chime In On The Most Intriguing Aspects Of Cylinder Head Port Design. The intricacies of airflow dynamics through a cylinder head ...

The choke valve in an engine's carburetor, whether it's a Holley carburetor or another brand, helps a cold engine start by restricting some of the airflow into it. When the engine is cold, the choke ...

Two-stroke engines have steadily fallen out of favor over the last 50 years or so. While they sport great power-to-weight ratios and are often much simpler mechanically than their four-stroke ...
