That’s what happened to a man named Aaron and he took to TikTok to tell viewers an important driving tip after his friend ...

A diesel engine is simultaneously incredibly simple and incredibly violent, using compression as a means of ignition. This is because of the properties of diesel fuel: Namely, diesel is less volatile ...

As a diesel owner, I know the hectic heartbreak of trying to keep such an unpopular drivetrain up and running in the U.S. Most people think of big semi trucks when they think of diesel, or they think ...

We all know diesel engines produce Earth-moving torque to outclass gas engines in pulling power and heavy-duty workloads. We also know that diesels could outlive a similar gas engine, given proper ...

Ever been told your car is running lean? It means the engine is receiving too much air or not enough fuel during combustion. You see, your car's engine needs a very specific balance of air and fuel to ...

Modern diesel engines perform exceptionally well at 1,100 to 1,200 rpm. They deliver peak torque just a few hundred rpm above idle, and peak horsepower somewhere around 1,500 or 1,600 rpm. But what ...

The NASA team developing the X-59 supersonic demonstrator jet have fired up the aircraft’s GE Aviation F414-GE-100 powerplant for the first time, having started engine-run tests on 30 October. The ...

How often do you hear drivers complaining about weak engine brakes? Some drivers will say the engine brake provides so little retarding power they have to use their service brakes to help decelerate ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

Astronomers have found a relatively tiny galaxy whose black-hole-powered “central engine” is pouring out energy at a rate equal to that of much larger galaxies, and they’re wondering how it manages to ...

I’m not sure if any engine built today will still be salvageable 100 years from now. Not to sound like a grump, but so much relies on computers that will surely be obsolete by then. And let’s not get ...
