Automakers once bet big on bizarre ideas—from swirling airflows to variable compression—and the results were as fascinating as they were short-lived. Automotive engineers have invested countless ...

Navistar’s new International S13 Integrated Powertrain, designed in close collaboration with the Traton Group for the North American market, is the last internal combustion engine powertrain the ...

Mazda patents a complex 6-stroke engine that generates hydrogen from gasoline, offering zero emissions and daily operation ...

Hydrogen combustion engines are inefficient, costly to maintain and worse for the environment than fuel cell or battery powertrains. But they're also noisy and fun, so automakers are starting to pitch ...

Look, as cool as it could be and as much as automakers want it to happen, a worldwide switch to hydrogen passenger vehicles is just not realistic or even possible. But as the technology improves, ...

Here are some of the technologies that are extending the life of the internal combustion engine by making it more efficient. Displacement on demand: Shuts down unneeded cylinders once a vehicle ...

Although the electric revolution is making big strides, the internal combustion engine is far from dead. So what’s does the future hold for it? Jason Fenske from Engineering Explained is here to lay ...

The original concept of combustion engines as we understand them dates as far back as the late 1800s. And while they are more or less a solved science today, they definitely didn't start that way.
