Q

The starting air supply for a diesel engine is generally produced by a/an __________.

🔍 Key Concepts

• Starting air systems for medium and slow-speed diesel engines • Difference between devices that boost intake air during running vs. equipment that stores high-pressure air for starting • Typical pressure range of starting air (in bar or psi) and what type of machinery is used to achieve it

💭 Think About

• Which of these options is normally used to create and store high-pressure air (often around 20–30 bar or higher) in air bottles for starting large diesels? • Which devices in the list mainly function only when the engine is already running, and which can operate independently to build up pressure before starting? • Think about the mechanical design of each device: which one is best suited for multi‑stage compression to high pressure with good efficiency?

✅ Before You Answer

• Identify which choices are primarily for scavenging/boosting intake air rather than for starting air storage • Check which type of compressor is commonly built as two or more stages to reach typical starting air pressures • Eliminate any option that depends on engine exhaust or crankshaft power that would not be available before the engine is running
