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 ...

The hunt for efficient engine valve technology can be a never-ending journey into cam timing, various combustion cycles, and lift and duration adjustments. For that reason, some companies believe ...

Prototype IVA engine swaps a usual longitudinal camshaft for short, individually driven camshafts sited across the top of the cylinder head. IVA cam drive is by ECU-controlled electro-mechanical ...

The 'Intelligent Valve Actuation ( IVA)' system that operates the intake and exhaust valves that are arguably installed in gasoline and diesel engines with only the power of an electric motor is a ...

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 ...

Taking care of your vehicle is vital to ensure it stays in great condition. Your brakes could give you trouble someday, or your suspension could require tinkering, inevitably leading you to an auto ...

Your engine is composed of many moving parts and pieces. In order to move through the four stages of internal combustion, all of these bits and bobs are quite necessary. Some engines, however, take ...

Freevalve seems to be taking an all-of-the-above approach with its so-called pneumatic-hydraulic-electronic actuators. But air does the work. The team first employed this solution on the Scuderi Split ...

March 30, 2007 Over the last century of automobile development, we have seen an enormous range of valve actuation technologies, ranging from pushrod, through single then double overhead camshafts, ...

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.
