While underway, which of the following would be the FIRST step in reversing a direct reversing large, slow-speed, main propulsion, diesel engine?

🔍 Key Concepts

• Operation sequence of direct-reversing slow-speed diesel engines • Purpose of the camshaft position (ahead/neutral/astern) in timing fuel and exhaust events • Role of safety interlocks and fuel racks during direction changes

💭 Think About

• Before an engine can safely turn in the opposite direction, what must be true about the valve and fuel timing controlled by the camshaft? • Which actions listed would normally happen after the timing has been set for the new direction, rather than as the very first step? • Think about which option changes engine timing versus which options change fuel or protection devices.

✅ Before You Answer

• Identify which choice deals directly with valve and injection timing needed for reversing direction. • Determine which actions are part of safety/protection systems that should not be the first thing you touch in a normal reversing operation. • Consider the normal reversing sequence: timing set → interlocks satisfied → fuel re-admitted. Which option best matches that initial timing step?
