In this transitional period between the gasoline and electric ages, there's still plenty of room, and plenty of motivation, for last-gasp improvements to the combustion engine – and a Swiss R&D ...

Secondly, adopting a digital valve train introduces a deluge of new variables that engineers can play with. There might be all sorts of benefits available, but getting to them requires an incredible ...

With the short block assembled for our 383 supercharged project motor, it's time to shift our attention once again; this time to the heads and valvetrain. Like the rotating assembly, when it came to ...

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 ...

Late-model engines have spoiled us. The LS-series engines are so well engineered that many car crafters consider them indestructible, which isn't exactly the case. But there is something to be said ...

This installment of Toyota's Engines 101 series takes a closer look at one of the most critical parts of an engine: its valvetrain. The video establishes what parts comprise a valvetrain, looks at ...

Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

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 ...
