M/E1. How does a marine diesel engine work? A charge of fresh air is pumped into the engine cylinder and then compressed by the moving piston to a very high pressure. When the air is compressed, its temperature rises so that it ignites the fine spray of fuel injected into the cylinder. The burning of the fuel adds more heat to the air charge, causing it to expand and force the engine piston to do work on the crankshaft which in turn drives the ships propeller.2. four stroke of the engine : Suction CompressionExpansionExhaustIt takes two revolutions to make one power stroke for a four stroke engine.3. Before a large diesel started it must be warmed through by circulating hot water through the jackets This will enable the various engine parts to expand in relation to one another.Boiler1. The function of the boiler:Boiler is use to heat feed water to produce steam to heat the fuel oil and lube oil and the galley needs the steam to heat foods too.A drum must be provided where steam and water can separate.2. The types of the marine boiler(1) Fire tube boilers:The furnace hot gases pass through the tubes while the water is on the outside. (2) Water tube boilers The water through the tubes while the hot furnace gases pass around the outside3. What is the commonly used boiler?Exhaust boiler and oil-burning boiler.3. Boiler mountings:Safety valves; Main steam stop valve; Auxiliary steam stop valve; Water level gauge; Blow down valve; Scum valve; Soot blowers. Marine pump1. A pump is a machine used to raise liquids from a low point to a high point.2. There are three main classes of pump in marine use 1.displacement 容积式泵 2.axial flow 轴流式泵3.centrifugal 离心泵3. An air vessel usually fitted in the discharge pipe to dampen out the pressure variations during discharge.4. A diffuser is fitted to convert the kinetic energy (energy of motion) of the liquid into pressure energy Marine Electrzation1. A current is produce when a coil of wire is rotated in a magnetic field2. When the current is collected using a ring split into the halves (a commutator) , a direct direction current is produced. 3. When the current is collected using two spilt rings which are insulated from the shaft we get alternating current that is changing in direction and rising and falling in value.Marine refrigeration1. The natural transfer of heat is from a hot body to a cold body, the function of a refrigeration plant is to act as a heat pump to reverse this process so that the room can be maintained at a low temperature.2. 冰机的四大部件 Four components of the ice machine: Compressors,Condensers,Expansion valve,Evaporator Others1. Can you name some tools used in the engine room?Screwdrivers 螺丝刀Hammers 锤子Spanners 扳手Pliers 钳子 2. Whats the function of the fuel oil separator?Its used to treat the fuel oil and remove water and impurities from fuel oil before it is pumped into the engine.3. What is the function of the oily water separator?It is used to ensure that ships do not discharge oil overboard in order to prevent oil pollution. It is one of the antipollution equipment. (Antipollution equipment:Oily-water separator; Sewage water treatment unit; Incinerator)4. What is the function of the centrifuge?The centrifugal separator is used to separate two liquids, for example oil and water, or a liquid and solids 5. Please name some types of vessels in the world答： There are cargo ship, container ship, tanker, passenger ship, ro-ro ship , chemical ship , and so on.6. How many departments are there on the board?答：There are two departments: the deck department and the engine department.7. What courses have you learned during your studies?Main propulsion diesel engineShips automationShips managementEnglish of marine engineeringAuxiliary machinery and so on.8.

Deck machinery? Anchor windlass; Mooring winch;Hatch cover; and so on.11. if you work as a 4/E, tell me something about your duty答 1. Watch keeping from 8:00to 12:00 both in the morning and in the evening.3. be responsible for maintenance and repair of Boiler,Pumps,Pollution prevention equipment,Life-boat engine and so on.12. Fuel oil separator (used to treat the fuel oil and remove water and impurities from fuel oil) include purifier and clarifier.13.What should be done before carbon dioxide is released to the engine room？Before carbon dioxide is released, the alarm should be given and all the crew in the engine room must leave right away and Close all the door and windows,Stop the generators,Start the emergency generator, Release steam pressure in the auxiliary boiler; Shut all quick closing valves for oil tanks, Stop all ventilations and so on.14. What is used for cargo handing? Crane or Cargo winch.15 What is SWL of the crane? Safety working load.16. What is restricted area? Usually the radio room and the chart room. 17. What equipment does PSCO usually check in the PSC inspection? Emergency equipment 应急 Firefighting equipment 消防 Life saving equipment 救生 Pollution prevention equipment 防污染18.
