Interesting Engine Designs

Posted: August 13, 2010 in Automotive Technology

I’ve always been a fan of the Wankel Rotary Engine that have been used in Mazda’s for decades, so it was really interesting to come across some other combustion engine designs that don’t require a reciprocating piston. For those not of the engineering background (like myself), it is a little hard to get your head around some of the concepts and trying to visualize the concepts in your head. But have a look at the video’s anyway.

Concentric Rotary Engine

Libralato Engine

Quasiturbine Rotary Engine

Edward’s Winged Rotary Engine

Turbocombustion Engine

Possible issues with these designs:

– Complexity

– Sealing issues

– Mechanical wear and tear

– Fuel efficiency and emissions

Nonetheless great effort from the respective patent owners.
