🔍 Key Concepts

• Function of diesel engine cylinder head test cocks on medium and slow-speed engines • How indicator diagrams/pressure readings are taken from individual cylinders • Typical locations and uses of lubrication checks and pyrometers

💭 Think About

• Ask yourself: when you want to see what is happening to pressure inside a single cylinder while it is running or being tested, where would you connect your measuring device? • Think about whether cylinder lubrication is normally checked through a small cock in the head, or by observing another system/component. • Consider what kind of fitting exhaust gas pyrometers use, and where they are usually installed relative to the cylinder head.

✅ Before You Answer

• Identify which choice describes a function that directly involves measuring or monitoring cylinder pressure. • Eliminate any options that involve equipment normally fitted in the exhaust manifold, not directly to a small test cock in the cylinder head. • Confirm whether cylinder head ‘test cocks’ are intended for ongoing operation or for occasional testing/measurement access.
