Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

Honda might be looking back to early aeronautics in its latest bid to make variable compression engines simpler and sturdier. The engine is designed to take advantage of the simple crank design of ...

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
