You'd think measuring an engine's displacement would be simple, but there's a long history of trying to figure out how to categorize the Wankel.

Essentially, a multi-cylinder engine is a collection of individualengines operating at different combustion and mechanical efficiencies.If we can optimize the power output from each one, the overall ...
