Question

identify the designated component of the rotary engine assembly in the image above.
a. combustion chamber
b. apex seal
c. exhaust manifold
d. eccentric shaft

Explanation:

To identify the component, we analyze each option:

• Option a (Combustion chamber): The combustion chamber in a rotary engine is the space where combustion occurs, but the designated component here is a seal on the rotor's apex.
• Option b (Apex seal): Apex seals are crucial components of a rotary engine, fitting on the apex of the triangular rotor to seal the combustion chambers, which matches the designated part in the diagram.
• Option c (Exhaust manifold): The exhaust manifold is for expelling exhaust gases and has a different structure, not matching the component here.
• Option d (Eccentric shaft): The eccentric shaft is the central shaft the rotor rotates around, not the designated component.

Answer:

b. Apex seal
