Q

Which of the components listed is only found in an opposed-piston engine?

🔍 Key Concepts

• Opposed-piston engine layout – how pistons, crankshafts, and ports are arranged • Difference between ports and valves in 2-stroke diesel engines • Which components are common to almost all internal combustion engines (gasoline and diesel)

💭 Think About

• Picture a normal single-piston diesel engine: which of these components does it already have? • In an opposed-piston engine, there are two pistons in one cylinder moving toward each other. Which listed component is uniquely needed to make that motion work? • Which items in the list are general engine parts that would also exist in non–opposed-piston designs?

✅ Before You Answer

• Identify which choices are generic to all internal combustion engines (those are less likely to be unique to opposed-piston designs) • Separate valves from ports – ports are openings uncovered by piston movement, valves are separate moving components in the cylinder head • Ask: in an opposed-piston engine, where would each listed component physically be located, and does that layout require something not present in a conventional single-crankshaft engine?
