Q

Carbon deposits forming on the discharge valves of an air compressor are caused by oil deterioration under high pressure. The first step in reducing these deposits would be to __________.

🔍 Key Concepts

• Carbonization of lubricating oil in high-pressure compressors • Effect of temperature vs. pressure on oil breakdown and deposit formation • How oil viscosity and volatility influence lubrication and deposit tendencies

💭 Think About

• Which option directly addresses the main cause of the oil breaking down into carbon: is it more about temperature, pressure ratio, or the type of oil? • If oil is already deteriorating and leaving carbon, would increasing compression ratio, viscosity, or volatility make that better or worse? Why? • Think about what change would most likely keep the oil from reaching its breakdown temperature in the first place.

✅ Before You Answer

• Identify which choice would lower the oil film temperature at the discharge valves. • Eliminate any option that would clearly increase heat load or stress on the compressor stages. • Check which lubrication change (viscosity or volatility) would reduce, not increase, the risk of carbon deposits in hot, high‑pressure areas.
