Ro­tary mo­tor ex­plained...

Motorcycle News (UK) - - This Week -

Wankel en­gines, more com­monly known as ro­tary en­gines, dif­fer from reg­u­lar en­gines as they don’t have a re­cip­ro­cat­ing pis­ton trav­el­ling up and down in a cylin­der. In­stead a tri­an­gu­lar shaped ro­tor spins in­side an hour-glass shaped hous­ing. Valves in the cas­ings al­low gases to trans­fer, sim­i­lar to a two-stroke, but un­like a re­cip­ro­cat­ing en­gine all the parts in­side move in the same di­rec­tion. This means the en­gine is smooth, com­pact and ca­pa­ble of de­liv­er­ing a high power-to-weight ra­tio.
