🔍 Key Concepts

• Trunk-type piston construction and how it differs from crosshead pistons • Common cooling methods for medium-speed diesel engine pistons • How heat flows from the piston crown to other engine parts

💭 Think About

• Think about where the hottest area of the piston is, and what practical paths exist to remove that heat in a trunk-type design. • Consider whether piston rings and the liner wall are designed primarily for sealing/wear, or if they are an efficient and intentional cooling path. • Ask yourself which of the listed methods are commonly engineered as a deliberate cooling system in medium-speed diesel engines.

✅ Before You Answer

• Verify the definition and layout of a trunk-type piston (what is directly connected to what). • Check standard references for piston cooling techniques in medium-speed marine diesels (e.g., oil-cooled crowns, gallery-cooled pistons). • Confirm whether piston rings are treated in textbooks as a main cooling method or mainly for sealing and lubrication.
