A rotary internal combustion engine in which a curvilinear, triangular, eccentrically pivoted piston rotates in an elliptical chamber, forming three combustion spaces that vary in volume as the piston turns.‘Having already bought the licence to produce Wankel engines, the decision was taken to go rotary.’
- ‘An internal combustion engine will produce 14-15 hp per gallon of fuel per hour (Wankel engines are a little worse, but we'll go with this figure.)’
- ‘And the latest incarnation of his Wankel engines seems to be taking off as a product in its own right.’
- ‘With the help of their Wankel engines, the company quickly rose in prominence.’
- ‘The RX - 8 uses a twin-rotor Wankel engine and it comes in two states of tune, called standard and high power.’
- ‘It's not as powerful as the initial projections led us to believe, and the Wankel engine uses oil and petrol in equal measure.’
1960s named after Felix Wankel (1902–88), German engineer.
