Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

Meet the Birotary, a crazy new and complicated engine that has three cylinders arranged like a star, a rotating block, a ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

In a single-cylinder engine, the ability to homogenize and maintain the fuel-air blend prior to and during the burn is a classic combustion-engine problem. Add additional cylinders, and introduce ...

Half a dozen countries, including the U.K. and possibly also Germany, have now laid out plans to ban gas- and diesel-powered vehicles, while tough U.S. and Chinese emissions and mileage standards are ...

It's amazing that an object as simple as a piston can withstand the rigors of combustion for hundreds of thousands of miles without failing. There's a lot more to a piston than meets the eye, matey.

While there's been a number of cars launched into space – a couple human-driven ones on the moon, a bunch of robotic ones on Mars, for example – no internal-combustion piston engine has ever left ...

Ferrari is exploring a groundbreaking approach to the internal combustion engine, as revealed by a recent European patent filing. Departing from the industry-standard round pistons, this new design ...

According to fleet executives as well as fleet maintenance managers, the death of the internal combustion engine may prove to be greatly exaggerated in spite of the excitement about electric ...

Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

At a time when heavy-duty internal combustion is frequently castigated in the shadow of zero-emission all-electric and fuel cell powertrains, a leading non-profit clean transportation group is ...
