The line identified as "I" in the...

🔍 Key Concepts

• Identify what type of device is shown on the RIGHT side of the illustration (cam-driven pump or valve actuator). • Trace where line I starts and ends in the system and what component it connects to in the cylinder cover. • Recall the normal flow path for fuel oil, lubricating oil, cooling water, and exhaust gas in a medium-speed diesel cylinder head.

💭 Think About

• Look closely at the part labeled H. Does it resemble a plunger-type pump or a valve housing, and what fluid would that pump normally handle? • Follow line I from H toward the cylinder head. Which component in the head would need a small, high‑pressure line like this? • Compare the size and shape of line I with what you’d expect for exhaust piping, cooling water piping, or oil lubrication lines.

✅ Before You Answer

• Verify whether exhaust gas lines in the figure are large or small compared with line I. • Check if line I is connected to any spring-loaded nozzle or valve tip that enters the combustion space (typical of an injector). • Confirm whether a cooling or lubricating line would normally run from a cam-driven plunger directly to the cylinder head, or if that is more typical of a fuel injection line.
