Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Ferrari has signaled a willingness to challenge one of the most fundamental assumptions in engine design by filing a European patent for oval-shaped pistons, a move that could reshape how future ...

Ferrari is exploring radical oval pistons that could shrink engines, boost efficiency, and reinvent how high-performance gas motors are designed for the next generation. For as long as internal ...

It looks like GM is working on modernising two-stroke engines by tackling their emissions problem. This could open a whole new chapter for internal combustion. It’s been a while since two-stroke ...

Porsche filed an engine patent for a W18, and it could power everything from hypercars to SUVs to nothing at all. Well, it means everything, or nothing or something in between. The truth is that ...

More an ancient tool than a groundbreaking gadget, the fire piston relies on basic chemistry to ignite a campfire with the simple pump of a hand. The new Aviator's Ember from Aerohart applies ...

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 ...

Back in the early days, diesel engines were for trucks, tractors, and stationary applications. They were deemed too heavy, too complicated, and too unrefined to be fitted onto a road car. Well-known ...

The creation of the motore a scoppio (the internal combustion engine) is one of the most important milestones in the history of modern engineering, and its first working version was developed in 1853 ...

When examining high-performance and mainstream internal combustion engines, the question of piston material is crucial to both reliability and output. Pistons are subjected to immense pressure, heat, ...
