With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...

When it comes to unconventional engine design, few exceed the Wankel rotary in terms of weirdness. Despite that, the same basic principles of internal combustion apply here: Fuel and air are mixed and ...
