Engine Operation

5 lessons

Starting, reversing, manoeuvring and stopping: two-stroke and four-stroke operation with the alarms and interlocks that guard each step.

This chapter collects 5 illustrated lessons on Engine Operation as part of Marine Propulsion & Diesel Engines, ordered as they are best studied. It opens with Two-Stroke Main Engine Standby & Start Preparation: Preheating, Turning Gear, Blow-Through & Bridge Control Changeover, Starting & Reversing the Two-Stroke, Manoeuvring, Port Ops & Engine Vigilance, Four-Stroke Operation — Alternator Duty, Starting Air System Physics, Explosions & Air Distributor. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
