As far as electric propulsion is concerned, the vast majority of applications make use of some kind of rotational motor. Be it induction, universal, brushed or brushless, these are the most efficient ...

Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...

The key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

A variety of two-stage, or discrete, variable valve lift (DVVL) and continuously variable valve lift (CVVL) systems have recently been incorporated in production vehicles. Several systems that have ...

I am disappointed every time I see the flow coefficient C v used to size a valve without consideration given to the other components in a pneumatic circuit. In the old days, a focus on the valve alone ...

The truly cool thing about internal combustion engines is there's always another creative way to skin the power/efficiency/emissions cat. Fiat's Multiair technology is a prime example. Even though ...
