In the Otto cycle, the induction stage involves which valve condition according to the provided material?

Explanation:
In this material, the induction stage is viewed as the charging of the cylinder and the preparation for compression, which is achieved by closing the inlet valve. Closing the inlet valve traps the air-fuel mixture inside the cylinder so the piston can begin compressing it on the next stroke. If the inlet valve stayed open during induction, the charge would leak back into the intake, preventing proper compression. So the valve condition described for induction is that the inlet valve is closed.
