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 ...

To evaluate isokinetic shoulder flexor–extensor (F/E) and abductor–adductor (Ab/Ad) torque ratios in individuals with paraplegia using a new interpretative approach. We proposed to study torque ratios ...

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 ...

Turbocharged engines make big torque at low rpm, but those two numbers, peak torque and its corresponding rpm, don’t tell the full story, as boost pressure isn’t solely a function of engine speed. A ...

What's the difference between horsepower and torque? What does it mean to me? An explanation of horsepower and torque, and a ...

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 ...

How many times have you heard that a crankshaft, connecting rod, or even forged piston is good for 13 psi of boost? On the surface, this seems reasonable, but the reality is that boost is far from ...

To paraphrase Janis Joplin, O Lord, won't you buy me the new Mercedes-Benz? The S65 AMG Coupe, in particular. The line-topping, twin-turbocharged 6.0 liter V12-powered two-door is expected to rocket ...
