🔍 Key Concepts

• Understand the flow of air through a turbocharged diesel engine – from ambient air, through the filter/silencer, into the compressor (blower) side of the turbocharger, then to the engine • Know the difference between the turbine side (exhaust gas side) and the compressor/blower side (fresh air side) of a turbocharger • Typical shipboard practice for locating intake filters/silencers with respect to the engine (local vs. remote)

💭 Think About

• Ask yourself: does it make more sense to filter and silence incoming fresh air before it reaches the compressor, or on the exhaust gas side where temperatures and soot are high? • Think about noise and maintenance: is it more practical on most vessels to keep the intake filter/silencer close to the engine, or run long ducts to a remote location? • Visualize a common turbocharger: which side actually ingests outside air, and which side is driven by hot exhaust gas?

✅ Before You Answer

• Identify clearly which side of the turbocharger is the turbine (exhaust) side and which is the compressor (air intake) side • Confirm whether filters/silencers are normally placed on fresh air intake, not on hot, dirty exhaust flow • Decide whether "local to the engine" or "remote" better matches what you would see in a typical engine room installation on most commercial vessels
