In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard ...

We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

Don't let failing oxygen sensors compromise your engine's performance. O2 sensors are critical to emissions control on your car, SUV or truck. As the name implies, the O2 sensor (also called an ...

The engine test stands used with advanced data-acquisition systems require a different type of pressure sensor than those used in the past. Engine hydraulics and pneumatics operate faster and often, ...

Microchip Technology Inc. has extended its family of inductive position sensors into the electric-vehicle (EV) motor control market, with the launch of the LX34070 IC. Designed for EV motor control ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

What’s being described as an “onboard weather station,” the 3.6L twin-turbo LF3 V6 engine launching in the 2014 Cadillac XTS Vsport and 2014 CTS Vsport this fall is equipped with a set of sensors that ...

Last month we fielded a question about a fault code a reader had been trying to repair for more than a year. To recap, the Corvette in question, a ’96 model, had a recurring P0171 code, or “System Too ...
