Question

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

a. stationary gear

b. rotor housing

c. intake manifold

d. rotor

Explanation:

To identify the component, we analyze each option:

• Option a (Stationary gear): The stationary gear in a rotary engine is the fixed gear at the center (the yellow gear - like structure in the image, but wait, no—wait, the designated line? Wait, no, let's re - check. Wait, the options: Rotor housing is the outer casing, intake manifold is for air/fuel intake, rotor is the triangular part. Wait, no—wait, the stationary gear is the central fixed gear. But wait, the question's designated component—wait, maybe I misread. Wait, the options:
• a. Stationary gear: In a rotary engine, the stationary gear is the gear at the center that doesn't rotate, meshing with the rotor's internal gear.
• b. Rotor housing: The outer casing that encloses the rotor, has the combustion chamber shape.
• c. Intake manifold: Part of the intake system, not the central gear - like or rotor - like.
• d. Rotor: The triangular (or epitrochoidal) part that rotates.

Wait, looking at the image, the central yellow - like gear - structure is the stationary gear? No, wait, maybe the designated line is pointing to the stationary gear? Wait, no, let's think again. Wait, the rotor has an internal gear that meshes with the stationary gear (the fixed one at the center). So if the designated component is the central gear - like thing, it's the stationary gear. Wait, but let's check the options again. Wait, maybe I made a mistake. Wait, the rotor is the triangular part, rotor housing is the outer shell, intake manifold is for intake, stationary gear is the central fixed gear. So the correct answer should be a. Stationary gear? Wait, no, wait—wait, maybe the designated line is pointing to the stationary gear. Let's confirm:

• Rotor housing (b) is the outer part with the circular shape and bolts.
• Intake manifold (c) is the part for bringing in air/fuel, maybe the blue or gray part on the side.
• Rotor (d) is the triangular (epitrochoidal) part with the internal gear.
• Stationary gear (a) is the central gear that doesn't rotate, meshing with the rotor's internal gear.

So if the designated component is the central gear - like structure, then it's the stationary gear (a).

Answer:

a. Stationary gear
