The story of how Honda developed an oval-piston race engine that ultimately failed but still made history along the way.

Toyota is revolutionizing the automotive industry with its groundbreaking W-Piston Free-Piston Engine, which achieves an impressive 50% efficiency. This innovation not only promises enhanced ...

Engine cylinders can misfire due to problems with the ignition system, the fuel system, air and compression, or sensors and ...

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. Oval pistons could also lower ...

Friction is the enemy of speed. Whether it's rolling resistance or the wind flowing over the body at speed, racers work tirelessly to dispense it. The concept of friction may seem like an entirely ...

From a radical new Honda three-cylinder engine, to Ferrari's wacky oval-shaped pistons, to the latest Toyota Hilux, things ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

Science isn’t fun if we don’t try to break or bend its limits, but sometimes this rebellion doesn’t work. For instance, we don’t make triangular wheels, perforated windshields, or lead pistons for ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...
