Explore how 1930s submarine technology is reinventing modern trucking. Learn how Achates Power and the legacy of Rudolph ...

In an internal combustion engine, air and fuel are injected into the cylinders, where ignitions occur in a controlled environment. The combustion cycles force pistons to move, and that movement is ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

How boxer engines work, why they’re not just “flat” engines, and a 120-year evolution traced from the 1899 Benz to the latest Porsche and Subaru boxers. Boxer engines feature flat, opposing pistons ...

Two-stroke engines have largely fallen out of fashion when it comes to newer vehicles. However, GM appears to have not ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal ...

You've seen plenty of weird engines on Jalopnik, from Trojan's weird two-stroke, four-cylinder cube with wishbone-shaped connecting rods to the Napier Deltic triangle-18 diesel, but never have you ...

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 ...
