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 ...

How much power can you get from forced induction? Under optimum conditions you can experience as much as a 50 percent increase. However, this is the real world and your numbers are likely to be less.

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 ...

Upgrading your engine from a flat-tappet valvetrain to roller comes with a lot of advantages—mainly more power and radically reducing the chances of wiping a camshaft lobe—but it also requires a few ...

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 ...

When it comes to modern internal combustion engines, there are two types that dominate the industry: pushrod and overhead camshaft (OHC). While pushrod engines were the stars of the show for many ...

The pursuit of higher performance (greater than stock) is one of the many things that make the diesel scene as awesome as it is. Although experimenting with new parts concepts and technical theories ...

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 ...

Suck, squeeze, bang, blow. These are the four strokes of the reciprocating, internal-combustion engine (ICE) that Nikolaus Otto patented in the 19th century. The action of the intake valves that allow ...

A British company has developed a digital valvetrain drive system that, it claims, can give petrol engines a diesel-level of efficiency and fuel economy with much lower NOx emissions. The inventors ...
