Tried to be sneaky and just translate and copy the English wikipedia page but I feel this sloppy work would be found out
#maybe not I'm already very English poisoned#The Wankel engine has a spinning eccentric power take-off shaft#with a rotary piston riding on eccentrics on the shaft in a hula-hoop fashion. The Wankel is a 2:3 type of rotary engine#i.e.#two-thirds of its ideal total geometrical volume can be attributed to displacement. Thus#its housing's inner side resembles an oval-like epitrochoid#whereas its rotary piston has a trochoid (triangular) shape (similar to a Reuleaux triangle)#and the Wankel engine's rotor always forms three moving working chambers.[22] The Wankel engine's basic geometry is depicted in figure 7. S#not being guided by the external chamber. The rotor does not make contact with the external engine housing. The force of expanded gas press#All practical Wankel engines are four-cycle (i.e.#four-stroke) engines. In theory#two-cycle engines are possible#but they are impractical because the intake gas and the exhaust gas cannot be properly separated.[15] The operating principle is similar to#Wankel engines typically have a high-voltage spark ignition system.[25]#In a Wankel engine#one side of the triangular rotor completes the four-stage Otto cycle of intake#compression#ignition#and exhaust each revolution of the rotor (see figure 8.).[26] The shape of the rotor between the fixed apexes is to minimize the volume of#respectively.[23][27] As the rotor has three sides#this gives three power pulses per revolution of the rotor. All three faces of the Wankel's rotor operate simultaneously in one revolution.#one power pulse is produced at each revolution of the shaft. For comparison#the four-stroke piston engine completes the Otto cycle in two revolutions of its output shaft (crankshaft). The Wankel thus produces twice#Wankel engines have a much lower degree of irregularity when compared to a reciprocating piston engine#making the Wankel engine run much smoother. This is because the Wankel engine has a lower moment of inertia and less excess torque area due#a two-rotor Wankel engine runs more than twice as smoothly as a four-cylinder piston engine.[29] The eccentric output shaft of a Wankel eng#000 or 8#000 rpm. In practice#automotive Wankel engines are not operated at much higher output shaft speeds than reciprocating piston engines of similar output power. Wa#I...
