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 ...

For more than a century, one basic layout has quietly powered everything from family sedans to fighter trainers and lawn ...

The vast majority of personal airplane engines are air-cooled, a traditional design that prioritizes light weight and relies on efficient airflow for heat dissipation. Pilots manage engine heat using ...

While there have been many unusual engine designs over the years, there haven't been many advancements involving the inner workings of the piston engine, except for higher-quality components, since ...

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 ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.

Aircraft piston engine cylinders are a common weak point, susceptible to failures such as cracking, valve damage, and head/barrel separation due to the extreme heat cycles they endure. Excessive heat ...

This video provides an in-depth analysis of the liquid piston engine and compares it to traditional piston engines and Wankel ...
