Camcon's Intelligent Valve Technology (IVT) replaces the camshaft with electric actuators for full, precise digital control over the air charge of any engine. Now, the company's focus is shifting from ...

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 ...

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 ...

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.

Last month's "How It Works" story gave you the basics of the four-stroke cycle, describing the motion of the intake and exhaust valves in relation to the piston moving up and down in the cylinder.

At its most basic level, an engine is an air pump. Internal combustion engines breathe fresh air and expel wasted exhaust gases to make power. Something has to tell those intake and exhaust valves ...

The typical four-stroke engine is made up of hundreds of parts. These parts are all designed and engineered to work together to make a prescribed amount of power, torque, engine longevity, and other ...

Vehicle engine designers are beset by conflicting demands. On the one hand, they must reduce costs as intense international competition is driving the need to cut product prices so that companies can ...
