It has fewer moving parts and allows for burning diesel, biofuels, gasoline, and green options like hydrogen. This is mainly because 1) the Wankel requires clearance at the corners between its side/face seals and its apex seals, while the X engine does not; and 2) the Wankel seals traverse across holes that contain spark plug(s), whereas the X engine does not. The direct-interfacing of the apex and face seals eliminates the need for corner seals of the typical Wankel engine, significantly reducing rotary engine blowby. Where the rotor holds the seals in a normal Wankel, the housing does that job in the X1 engine. Hungry Jack Mashed potatoes discontinued 2023 Do they still make it.
