That fresh air is squeezed into a small pocket in the center of the cylinder as both pistons come together, where finally diesel fuel is directly injected, igniting the mixture and creating the power ...

Air-cooled piston engines are common in aircraft due to their simplicity and the abundant airflow in flight, relying on a pressurized cowling and baffles to efficiently direct air over cylinder fins ...

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.
