PROCESS WORKING ENGINE

Of all the machines there are only two that work process work process work process four-stroke and two-stroke, the following will be discussed one by one

1. Process There are four engine work done two crankshaft rotations to get the power in four cycles and the cycle consists of the suction, Compression step, step of effort, and last step Discard

• Step suction the suction step, piston moves from top dead centre (TDC) in which the suction valve opens fuel into the combustion chamber and the valve closed Discard

• Compression step, the step piston moves up 15 degrees before TDC top dead centre towards the suction valve and the exhaust valve is closed the air and mist in the living fuel burn in the press or in the compressed because there is no space bagar little gap temperature will be higher, we remember the fire or burning occurs because there are three components of air, heat, and the media in this case then there is fuel combustion and explosion.

• Step effort, in this step the suction valve and the exhaust valve is in a closed state because of the explosion resulting from the step Compression causes the piston kicked off point towards the bottom of the work that led to the crankshaft rotates, turning the crankshaft power is generated, where the end of this step a little exhaust valve begins to open

• Step waste, is in step piston moves up from bottom dead center to the point of death for which the suction valve is closed and the exhaust valve open to remove the remaining residue is in the combustion chamber

 

2. Work Process meaning two-stroke engine is the engine performs two step in one round    piston crankshaft to produce a power which steps are

• The first step piston moves from top dead center (TDC) when these will hit the piston rinse the position in the space below the piston, piston ring at some point will go through the hole flushing / exhaust gas will enter through the hole gas income generally will be above the sinkhole and revenue hole would be slightly below, at the time of piston rings through the combustion of landfill gas will exit through this hole, when the piston ring passes through the hole in the intake gas pressure rinse chamber will be depressed into the combustion chamber and piston will push the gas 
• The second step piston moves up from bottom dead point (BDC) to top dead center (TDC) when the piston is going to suck air mixtures Lubricating oil and fuel, when the piston has passed the pit entry and discharge the piston moves up and to compression at 15 degree of lubricating oil mixture combustion chamber, the air and fuel ignite and cause an explosion was a result of the explosion will be repeated back to the first step and so on

ENGINE PARTS

After we identify that there are ships machining This time we will learn about the parts of the engine, in outline by how the machine works it is two moving parts and does not move

1. Moving parts 

• Rocker arm, this thing is like a chicken's head was exactly the way it works is like the head of a chicken pecking at food pressing the valve head / valve

• Push rod, push rod is worked up and down to push the rocker arm

• Valve, this valve there are two intake valve and exhaust valve, to distinguish them is by measuring the valve head is larger exhaust valve and the smaller is the suction valve, but there is a machine that only has the exhaust valve just for this section will be discussed later in the engine work

• Piston, piston engines operate when it moves up and down due to the compression pressure of the explosion the room is fuel burning fuel that will be forwarded to the crankshaft

• Crankshaft, part of this work and continue to change the spin of the work piston up and down a circular motion or rotary motion will be forwarded to the propeller shaft to drive the propeller blades

   

 

 

 

2. The second part of the machine is part of a still or not moving

•  Cylinder head, cylinder cover this as part and is part of the combustion chamber

• Cylinder liner, judging from the name cylindrical shape we can certainly imagine looks like a tube top and bottom open, cylinder liner is one part of the machine that serves to protect the inside of the cylinder block of piston ring friction

• Cylinder block, serves as a combustion chamber and the piston moves

in line type

"V" Type

• Carter, the engine needs lubrication for each machine that is certainly no such thing as charters to accommodate a number of engine oil is needed

 

 

 

 

 

 

 

 

Ship machinery

Once we know the type of ship the wrong kind only driving engine or the motor is then in time we will get into the ship to find out the existing machinery onboard without further ado we soon peeled one by one

• MAIN engine
  Main engine is the main power to drive the propeller shaft propeller which will be forwarded to the propeller blades to move the ship itself every ship is different depending on the size and needs are in one boat, there is one main engine there are two main engine depending on the size and needs of the vessel but does not mean the bigger the ship the more machines parent, the parent machine is generally located at down side for grounded ship propeller and axle follows Hero of the main engine.

• Auxiliary engine
  Auxiliary engine, this machine size, smaller than the main engine of the main functions of the auxiliary engine to drive the generator engine Electric boats we can imagine if there is no electricity onboard the vessel will be dark so that in place of the average auxiliary engine auxiliary engine on board more than one even up to have four auxiliary engines

•  Aircraft AuxiliaryIs the machinery that is intended to help the smooth operation of a ship machinery, general machinery are as follows
• The air compressor, air compressor is a tool on the production of lean air used to power early start on a machine that uses air propulsion or commonly known by the pneumatic propulsion system,

• Pump fuel pump is used to move the fuel from the tank creep (bottom tank) to the settling tank into tank holders before submission to the machine requires.

• Fresh Water Pump, pump serves to fresh water is supplied to the accommodation as the bathroom toilet, kitchen

• Cooling Pump, a machine that works 24 hours a day so that his name and the absolute need for a cooling pump that's mounted a name that aims to circulate cooling water cooling machine

•  Pump Ballast, when there is no cargo ship the hull will be lifted to the surface of the water with these conditions would endanger the safety of the vessel for which the ship is equipped with a pump ballast water into the tank to enter the ballast tanks, otherwise when ships loaded with the position of the vessel will be the entry of water into the ballast pump is used to pump out the water that was in the ballast tanks

• Bilge pumps, these pumps are made to pump water from the engine room bilge better and hold the ship

• Oil water separator, before the dirty water from the engine room and the hold should be dumped overboard through this tool that serves as the name suggests is separating water and oil so as not to pollute the ocean

• Purifier, this tool has the function to separate the oil and water before entering the machine

• Clarifier, is used to separate the oil and dirt such as mud debelum channeled into machine

• Sanitary pumps, fresh water on board while sometimes very limited amount of water is the most basic thing in life to provide it in the sanitary pump to pump seawater to memcukupi water needs of these pumps to pump sea water to clean the vessel, cleaning mud anchor , and to clean the dirt in the toilet

• Boiler, machinery is designed to generate steam which steam is generated can be used to heat the heavy oil before it goes into the machine, for space heating, and can also be used for cooking

• The crane / winch, crane machines as a driver that is in use for activities Unloading and loading cargo ship

Similarly, there is a glimpse of the ship machinery in general for more detailed discussion we will discuss in the post next post, may be useful
