Prior to starting, the purpose of turning over a main propulsion diesel engine with the cylinder test cocks open, is to __________.

🔍 Key Concepts

• diesel engine starting procedures and safety precautions • purpose of cylinder test (indicator) cocks on large diesel engines • what happens if water or fuel remains trapped in a cylinder when the engine starts

💭 Think About

• Think about what danger could exist inside a cylinder after the engine has been shut down for a while and before it is started again. • Ask yourself why you would want the cylinder space to be open to the atmosphere temporarily while you slowly turn the engine over. • Consider which of the answer choices describes a condition that must be made safe before normal starting and compression can occur.

✅ Before You Answer

• Identify the function of cylinder test cocks on slow-speed or medium-speed diesels (are they for measuring something, venting something, or lubricating something?). • Decide which options describe things that are normally checked with closed cylinders versus with the test cocks open. • Eliminate any choices that involve conditions (like compression or lube oil pressure) that require the engine to be turned under more normal starting or running conditions.
