Researchers are designing nano-sized quantum heat engines to explore whether they may be able to outperform classical heat engines in terms of power and efficiency. Researchers from Aalto University ...

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 ...

With the introduction of the new 5.0L, Four-Valve Coyote motor, the original Two-Valve has taken yet another step back in terms of popularity. The Three- and Four-Valve variants get all the publicity ...

3D prints aren’t typically known for their heat resistance. However, [Integza] noted that using the right techniques, it was possible to 3D print parts that could handle steam heat without failing.

Bob is a service technician who is well trained and nationally certified. However, he sometimes suffers from the same confusion that all technicians occasionally do - the facts that he gathers may or ...

American publisher Charles Knight was not at all impressed with his new 1901 Knox ‘gasoline runabout’. Like some other cars of the era, its four-stroke engine relied on a single valve to permit both ...

Give them the results of a TDC valve-drop static clearance test, and Comp Cam's techs can calculate the piston-to-valve clearance for any of its cams at any degree of rotation. This is especially ...
