🔍 Key Concepts

• Diesel combustion chamber types used in indirect injection engines (precombustion, swirl/turbulence, air cell, energy cell) • The shape and location of the small auxiliary chamber in view A relative to the cylinder and injector • How air and fuel flow between the main cylinder and the small chamber through a restricted passage/orifice

💭 Think About

• Look closely at where the injector sprays in view A: does it spray into the main cylinder space, or primarily into a small side chamber? • Compare the shape and size of the side chamber in A with the other views (B, C, D). Which label in the answer choices usually describes a single small chamber connected to the cylinder by one narrow throat? • Think about which term is more general and which terms refer to more specialized cell designs (like Lanova) — which one best matches the simple chamber arrangement in A?

✅ Before You Answer

• Verify whether the fuel is injected directly into the main cylinder or first into the small chamber in A. • Confirm if the small chamber in A is just one cavity with a single connecting passage, or a multi‑cell/compound cavity that would justify a more specific name like energy cell or air cell. • Make sure the term you pick correctly describes a general auxiliary combustion chamber rather than a design intended mainly to increase swirl/turbulence.
