Our mechanic takes us through the cylinder head and valve train and continues his explanation of how engines really work. The Mechanic is the kind of chap who eat, sleeps and breathes engineering.

The company is working in three directions to push things forward: it's building plug and play valve train kits for a range of common single-cylinder research engines, it's opening up to the ...

In order to set a stage for what follows, let's first revisit some of the fundamentals involved in how valve timing relates to power output. And to further clarify how "power" is defined in the ...

Valve train improvements are an important part of the continued efficiency advancements of internal combustion engines. Today's electronics allow more precise control and different approaches to valve ...

Scientists have developed an innovative, electrohydraulically actuated valve train for internal combustion engines, that enables completely free adjustment of stroke and timing, while at the same time ...

One of the new tools that engine builders are using these days to reduce fuel consumption and greenhouse gas emissions is Valve Control Management (VCM), ABB’s variable valve train system, more so ...

From Street Stock to Winston Cup, the three most important areas for engine performance improvements are cylinder heads, valvetrains, and intake manifolds. In particular, cylinder heads affect most ...

The valve train is the "respiratory organ" of combustion engines: it manages the aspiration of fresh air and the discharge of exhaust gases, which is referred to as "gas exchange". Today, only ...
