Q

On a diesel engine equipped with a Roots-type blower, __________.

🔍 Key Concepts

• Roots-type blower construction and how it moves air • How a mechanically driven blower behaves as engine speed changes • Where air compression actually occurs in a two‑stroke diesel with a blower

💭 Think About

• Think about what physically drives a Roots blower on a diesel engine. Does its speed depend more on engine RPM or on engine load? • Consider the air path: air cleaner → blower → intake ports/manifold → cylinder. At which point in this path is the air really being compressed? • Ask yourself how the blower lobes are supported and sealed. Would they normally share engine lube oil, or have a separate lubrication arrangement?

✅ Before You Answer

• Verify whether a Roots blower is a positive-displacement, mechanically driven device or a turbine driven by exhaust gas. • Check your basic engine diagrams: does any real compression happen in the air cleaner, or is that only a filtering stage? • Confirm from typical engine schematics whether the blower speed follows engine RPM directly (geared/shaft-driven) or changes with engine load.
