Talk about the equipment in engine room.There are all kinds of equipment in a typical engine room, such as themain engine, the auxiliary engine, the boiler, the oil separator, the fresh water generator, the incinerator, the oily water separator, all kinds of pumps and so on.The main engine is the most important one of all the equipment. It is usually a two-stroke low speed diesel engine. The auxiliary engines are usedto drive the alternators. They are usually four-stroke trunk piston engines. The steam on board is produced by the boiler. There are two distinct types about marine boilers in use, the fire-tube boiler and the water-tube boiler. The fresh water generator produces fresh water by evaporation of sea water. It can also be called an 'evaporator' or3'distiller'. A vacuum boiling evaporator consists of an evaporatingsection and a condensing section. The incinerator and the oily water separator are pollution prevention equipment in the engine room.2. The main engine in our engine room.The main engine is the most important one of the equipment in our department. It is a two-stroke low speed marine diesel engine. The main engine is used to drive the propeller. Because of low speed, it requires no reduction gearbox between it and propeller.In general, the main engine consists of two parts: the moving parts andthe fixed parts. The moving parts are also called the driving gear. These include the crankshafts, the connecting rods, the crossheads and the pistons. Among the fixed parts there are the bed plates, the frames, the main bearing and the cylinders. In addition to these main parts, the necessary system that should be used to run the main engine is fuel oil system, starting air system and cooling water system.We take good care of the main engine to ensure its good working condition. Everyday during the watch we note and verify the parameters of the main engine.And verify the parameters of the main engine. And at appropriate intervals we inspect it carefully.3. Look at the illustration and say something about the marine diesel engine.This marine diesel engine is two-stroke diesel engine. The scavenging method is uniflow scavenging. It is pressure charged.A marine diesel engine can be divided into two parts, the moving parts and the fixed parts. The main moving parts of the marine diesel engine are the piston, the connecting rod, the crankshaft and the piston rod. The main fixed parts of the marine diesel engine are the bedplate, the frame, the main bearing and the cylinder.In additional to these main parts, the necessary systems that should be used to run the diesel engine are fuel oil system, lubricating oil system, starting air system and cooling water system. These systems are very important to the marine diesel engine. Its successful operation and trouble free life depend on these systems.The diesel engine is a type of internal combustion engine. The marine diesel engine is a type of diesel engine used on ships.The operation between two injections is called a cycle. This cycle may be achieved either in four strokes or two. In a four-stroke diesel engine, the cycle requires four separate strokes of the piston. They are suction, compression, expansion and exhaust. If we combine the suction and exhaust operations with the compression and expansion strokes, the four-strokes, the four-stroke engine will be turned into a two-stroke one.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. Then the crankshaft in turn drives the ship's propeller.4. Look at the illustration and say something about the working cycle of the marine diesel engine.This is the exhaust turbo-charging illustration of a two-stroke of marine diesel engine.. As the air4density determines the maximum weight of fuel that can be burned. It also determines the maximum power that can be developed by the engine. If the charge-air density is increased by a compressor, a greater amount of fuel can be burned and result in an increase of power output.From the illustration, we can see that: The compressor is driven by the heat energy obtained from the engine exhaust gases. The gas-turbine is driven by the engine exhaust gases and directly coupled to the compressor (blower). The blower then draws fresh air from the engine-room and discharges it into the air inlet manifold on the engine. The air is pumped into the cylinder through the inlet ports. When air is burned, it becomes exhaust gases and discharge from the discharge valve which is on the top of combustion space. The exhaust gases then drive the compressor as describe above.The charge-air cooler is fit after the passage of compressor. Here,charge-air is cooled by cooling water and its density increases. Because the amount of air flowing into the cylinders is increased and as the charge-air temperature lowers, it is not only power output is increased, but also the exhaust temperature and the engine thermal load are reduced.5. Look at the illustration and say something about the exhaust gas turbocharger and supercharging.With supercharging a large mass of air is supplied to the cylinder by blowing it in under pressure. The exhaust gas turbocharger is the most commonly used on board to increase the density of the charge air.The exhaust gas turbocharger is composed of five parts: the air manifold, the exhaust manifold, the turbine, the compressor and the charge air cooler.The principle is as following: the exhaust air from the exhaust manifold enters the turbine room. Inertia of exhaust air drives the turbine. Theturbine is rigidly coupled to a centrifugal type air compressor. Then by the use of the compressor, the increase in charge air density is accomplished. Both four-stroke and two-stroke cycle engines may be pressure charged. The supercharging does a great favor to the thorough burning of the fuel. Then the output power is increased.The exhaust gas turbocharger is very important. We must pay attention toit and ensure its good working condition.6. Look at the illustration and say something about the cooling water system.The cooling water system is made up of jacket cooling water system and piston cooling water system. The coolant used in the cooling water system is fresh water. Cooling enables the engine metals to retain their mechanical properties.The main devices in the cooling system are expansion tank, jacket cooler, LO cooler, piston cooler, piston cooling water pump and so on. After leaving the engine, the jacket cooling water passes partially to the cooler and then into the jacket cooling water pumps, it is then pumped around the jacket.The expansion tank can ensure the jacket against cavitations effects. It can make up water due to leakages in the system. It can also ensure that the sea water can’t enter the fresh water system in the event of a small leakage in the jacket cooler.The cooling water system is very important. We must ensure it’s in good order and maintenance.5感谢您的阅读,祝您生活愉快。
