Camshafts are one of the most confusing components in an internal combustion engine. What makes those lumpy bumpsticks even more confounding is the sheer number of grinds available, and then multiply ...

Your car's camshaft — or camshafts if your vehicle has a DOHC engine — is a vital component that plays a critical role in the internal combustion process. Its job is to synchronize the opening and ...

Decades ago (OK, half a century or more), there was a product advertised in many of the performance magazines called the Varicam. The idea was a set of springs attached to a centrifugal device that ...

Although car manufacturers are embracing alternative power sources, they haven't given up on internal combustion just yet. Along with a push towards downsized turbo power, some of the smartest ...

When it comes to upgrading small-block engines, camshafts are a popular choice for enhancing performance. Different camshaft types can significantly alter how an engine breathes and performs, offering ...

GM has filed a patent application for so-called “Multilink Cranktrains with Combined Eccentric Shaft and Camshaft Drive System for Internal Combustion Engines.” The system is designed to provide ...

Electric cars are all the rage lately, but let’s not forget about the old standby – internal combustion. The modern internal combustion engine is a marvel of engineering. Today’s engines and ...

Camshafts are simple devices, but important ones. Modern engines can have one or more intake and exhaust valves, and it's the camshaft's job to open valves precisely as the engine runs, supplying the ...

At the heart of an internal combustion engine lies a series of cylinders, cylindrical chambers that house the fiery combustion process. These cylinders, arranged in various configurations such as ...

Engineers and analysts were understandably skeptical when Sweden-based supercar manufacturer Koenigsegg announced plans to design a piston engine that operates without a camshaft. Reinventing the ...
