OSHKOSH—Piper Aircraft has partnered with jet-fueled, diesel piston-engine maker DeltaHawk to give future buyers of PA-44 Seminoles a way to bypass the looming U.S. transition away from leaded avgas.

Multiple space agencies plan to return astronauts to the moon by the end of this decade. Along with commercial and ...

In this paper, the multi-rigid body dynamics analysis of the piston mechanism of D265-12 diesel engine is carried out, and the obtained data are combined with the acoustic-solid interaction theory, ...

Compared to other methods through various cross-domain diagnostic tasks on a piston aero-engine, the proposed method has obvious advantages in tasks with substantial inter-domain differences, ...

In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single opposed-piston engine. This unique project improves balance, reduces vibrations ...
