🔍 Key Concepts

• Air motion and turbulence in diesel cylinders during the compression and combustion strokes • How intake flow design and fuel spray characteristics each affect mixing of fuel and air • The role of cylinder size (swept volume) compared with how air and fuel are directed inside the cylinder

💭 Think About

• Which factor most directly controls how the air is set into organized motion (swirl/tumble) before fuel is injected? • Which option mainly affects atomization and distribution of fuel, rather than the basic turbulence of the air itself? • Does simply having a larger or smaller cylinder automatically create more turbulence, or is the way the air enters and moves more important?

✅ Before You Answer

• Be clear on the difference between air-flow-induced swirl/turbulence and fuel spray atomization/penetration • Consider which choice is determined at the engine/cylinder head design stage, not by operating conditions • Ask whether swept volume by itself can guarantee higher turbulence, or if a specific flow path/geometry is needed
