🔍 Key Concepts

• Volumetric efficiency in a reciprocating air compressor (what it measures and what affects it) • The effect of clearance volume and trapped hot air on the amount of fresh air drawn in • How valve timing and air temperature changes** can influence cylinder filling

💭 Think About

• Ask yourself: Which option directly reduces the mass/volume of fresh air that can enter the cylinder each intake stroke? • Consider which choice represents a condition that is progressively getting worse during operation, not just a normal part of the compression process. • Which factors are usually designed to be stable (set by design) versus those that might change with wear, carbon build‑up, or mechanical issues?

✅ Before You Answer

• Be clear on the definition: Volumetric efficiency = actual volume (or mass) of air taken in ÷ theoretical displacement volume. • Identify which choice would cause less fresh air to be drawn in on each stroke because of remaining high‑pressure, high‑temperature air in the cylinder. • Check which options are normal design features (and therefore not usually called a “loss”) versus which indicate a fault or degradation.
