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 ...

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 ...

Jacobs Vehicle Systems, a manufacturer of heavy-duty diesel engine retarding systems and valve actuation mechanisms, has launched a new 2-Step Variable Valve Actuation (VVA) system. By enhancing ...

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, ...

Valeo SA engineers say they are close to perfecting camless technology for traditional gasoline engines. A camless gasoline engine would reduce fuel consumption drastically -- 20 percent, according to ...

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 ...

February 2, 2006 UK-based RCV Engines is best known globally for its range of model aircraft engines but the unveiling yesterday of a prototype 125cc Rotating Cylinder Valve (RCV) scooter engine could ...

GM has filed a patent application for a two-stroke engine valve system. The patent application is tagged with patent number US 2025/0354528 A1 and was filed with the United States Patent and Trademark ...

Your engine feels calm at a stoplight because a hidden idle system keeps fuel, air, and spark in balance. That quiet stability is not luck, it is the result of sensors, valves, and software working ...

An engine depends on perfect timing the same way a symphony depends on a conductor. Every valve opens at the exact moment it should, every piston moves in perfect rhythm, and everything stays ...
