To begin, we know that both intake and exhaust systems operate with un-steady, pulsing flow. On the intake side, by comparison, this is probably more important to consider since (particularly when ...

Over time, in this column, we have touched upon several aspects of not only how to achieve higher levels of volumetric efficiency (as it relates to torque) but the importance of this feature in a ...

Where the 4.0-liter made peak power at 8300 rpm, the 3.0-liter makes peak power at 5500 rpm. Although the new twin-turbo six-cylinder doesn't have the stratospheric revs as the previous V-8, it makes ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

As the cost of electricity goes up, energy efficiency becomes more and more relevant as a design parameter. This is even the case in motion/position control applications, where servomotors are widely ...

Volvo's new XE13 and Eco-Torque powertrain packages will make a big difference to drivers in ways they will never know — and a few they will. What a difference a little extra engine torque makes. I ...
