🔍 Key Concepts

• Look closely at the label on the instrument body and dial that says DIESEL INDICATOR • Think about which diesel engine parameter normally reaches values up to 2000 psi on the dial shown • Consider which of the answer choices would require connecting directly to the cylinder indicator cock on the engine

💭 Think About

• Which engine measurement would need a heavy threaded connection and cock like the one shown, close to the combustion space? • Do exhaust gas pressure, jacket water treatment, or exhaust temperature balancing usually use a spring-loaded pressure gauge like this, or a different type of sensor? • On a medium or slow‑speed diesel, which pressure is high enough to need this type of rugged, high‑pressure gauge?

✅ Before You Answer

• Verify which parameter on a diesel engine commonly operates in the hundreds to low thousands of psi range • Check which measurement normally uses an indicator valve/cock fitted to each cylinder cover • Eliminate any options that would typically be measured with thermocouples, chemical test kits, or low‑pressure draft gauges, not with a mechanical indicator like this
