Question

identify the designated component of the rotary engine assembly in the image above.

○ a. stationary gear
○ b. eccentric shaft
○ c. exhaust manifold
○ d. rotor housing

Explanation:

To identify the component, we analyze each option:

• Option a (Stationary gear): A stationary gear in a rotary engine is fixed and meshes with the rotor's gear, but the designated part here (the central rotating shaft - like component) isn't a gear.
• Option b (Eccentric shaft): The eccentric shaft is the central shaft that the rotor rotates around, with an offset center. The designated component in the image (the central part with the rotational arrow) matches the description of an eccentric shaft.
• Option c (Exhaust manifold): The exhaust manifold is for directing exhaust gases and is not the central rotating component shown.
• Option d (Rotor housing): The rotor housing is the outer casing, not the central component.

Answer:

b. Eccentric shaft
