which of the rotary engine strokes is shown in the image above?
○ a. ignition stroke
○ b. exhaust stroke
○ c. intake stroke
○ d. compression stroke

Explanation:

To determine the rotary engine stroke, we analyze each option:

• Option a (Ignition stroke): In a rotary engine, ignition occurs when the fuel - air mixture is compressed, but the image doesn't show spark plugs firing (a key sign of ignition) in a way that aligns with ignition stroke characteristics.
• Option b (Exhaust stroke): The exhaust stroke is for expelling burned gases. The image doesn't show gas being expelled through an exhaust port in a way consistent with exhaust stroke.
• Option c (Intake stroke): During the intake stroke, the engine draws in the fuel - air mixture. The image shows the area where the mixture would be entering, with the rotor position allowing for the intake of the mixture, which matches the intake stroke.
• Option d (Compression stroke): Compression stroke involves compressing the fuel - air mixture. The rotor position and the lack of compression - related features (like a reduced volume for compression) rule this out.

Answer:

c. Intake stroke
