🔍 Key Concepts

• How air enters and leaves the cylinder in a two-stroke cycle diesel • Difference between ports in the cylinder liner and valves in the cylinder head • What component actually moves past the intake ports during engine operation

💭 Think About

• In a typical two-stroke marine diesel, where are the intake openings located: in the head or in the liner? • What engine part physically passes by these intake openings during each stroke and changes whether they are open to the cylinder or covered? • Which component is mainly responsible for operating valves rather than simple ports?

✅ Before You Answer

• Identify whether intake openings in this question refer to ports in the liner or valves in the head • Confirm which part has a reciprocating motion inside the liner and can cover/uncover ports • Distinguish between components that rotate to time valves versus components that slide to uncover ports
