The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

The Commer TS3 engine, built for Commer trucks from the '50s into the late '60s, didn't conform to design conventions of the time. Where most engines follow familiar blueprints with one piston per ...

Pistons play the ultimate role in an engine, but despite that, it's still hard to fully wrap your head around all the forces involved. There are plenty of moving parts in an internal combustion engine ...

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both ...

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 ...

The piston ends its downstroke and begins moving upward, compressing the air/fuel mix until combustion happens and the whole cycle begins anew. This means that the high torque efficiency of the ...
