Rotary engines

Don`t you just love them? That crazy uneven idle on peripheral port wankels?




It`s unbelievable such engines have been created, triangle spinning fast inside an oval. Who the hell came up with that idea?! Felix Wankel. Crazy Germans...
Mr. Wankel started designing the engine in 1951 and in 1957 the first working prototype wankel engine was built.

Even motorcycles has been built with wankel engine! British Norton Motorcycles and Japanese Suzuki had production motorcycles equipped with this simple piece of engineering.

Naturally aspirated wankel engines are great for tuning too, through intake porting you get easy power alot, yet depending on the type of porting you`re using, it increases fuel consumption and shorter life span. And other less important con`s (pro`s, more likely) like higher, more uneven idle and excessive noise.

Long live the rotaries!
