🔍 Key Concepts

• Identify the type of blower shown in the illustration (think: positive displacement vs. turbocharger). • Consider how a rotary-lobe / Roots-type blower moves air with each revolution. • Recall whether the lobes actually touch or if there is a small clearance between them.

💭 Think About

• Look at how many pockets of air are trapped and moved per revolution. If speed doubles, what happens to the number of pockets delivered per minute? • Compare this blower to an exhaust-gas-driven turbocharger. Which of the choices would better describe a turbocharger rather than a mechanically driven lobe blower? • If the lobes were in constant contact, what problems might that cause in terms of wear, lubrication, and sealing?

✅ Before You Answer

• Verify whether the blower is mechanically driven from the engine or by exhaust gas energy. • Decide if air flow in a positive displacement blower changes in the same direction as speed or in the opposite direction. • Confirm from the illustration whether there is clearance between lobes or if they are designed to rub together.
