There are THREE types of lubrication systems
| |
, batch system is used on a small four-stroke engine with its valves and cam shaft located on the engine block. The scoops mounted on the connecting rod big ends. When the crankshaft turns, scoops be smack in the lube oil reservoir. Lubricating oil will be splashed and wet, and lubricates the engine parts that move.

4 - The cam shaft
lubrication systems of this type of power supplies used in all medium and large vehicles. Lubricating oil in the oil reservoir will be pumped and filtered and then sent to the moving parts engine. Lubricants lubricate that will fall back into the oil reservoir is pumped back as a lubricant.
Types of Lubricants Oil Refinery
There are TWO kinds of censorship in the lubrication system:
Type the full refining
lubricating oil is pumped and then filtered and then sent to all parts of the move. If too dirty or clogged filter the lubricating oil can not lubricate the works, this can be dangerous engines. To overcome this problem a bypass valve installed in the filter will open and allow the oil out to lubricate even though not refined.
Type of bypass censorship
lubricating oil is pumped and then filtered part, while some were sent to the moving parts, although the situation is not refined. In a long time finally the oil will be refined as well. If dirty or clogged filters, lubricants and equipment to go to the moving parts for lubrication
Types of Pressure Indicator Unit Lubrication System
There are THREE types of pointing device pressure lubrication system normal
Type of indicator light
Many types of vehicles using the indicator lights for lubrication system. During the ignition switch on, contacts within the transmitter unit is closed. With this circuit is complete and the indicator light lights. When the engine of life, the pressure will be rejected diaphragm lubricant inside the transmitter unit continues to open contacts. Circuit is interrupted and the indicator lights go out. When the lights go out this show lubrication system works.
Type of loop balance
the low lubricating oil pressure, the resistance of the sending unit is low, it cause less current to go to the next loop and duplicate magnetic force weakens her veins. Armature and needle meter will be pulled into the main loop of magnetic force strong nerves to show a low reading. If high oil pressure, the resistance of the transmitter unit is also high, then the current will go to the second loop to the ground. Veins of the magnetic force on the second loop will get stronger. Armature with a needle meter will be pulled toward the second loop to show high readings value.
Bourdon tube type
oil pressure is transmitted directly from the main gallery connected to the meter pointer using bourdon tubes. During the low pressure, bourdon tube expands only slightly and pulled the little pointer. Meter shows low readings. When high-pressure bourdon tube will expand to many and will attract many of the pointer with the pointer is causing the high reading.
Damage Types of Lubrication Systems
To determine the type of damage and causes damage to the lubrication system, please see below
Bil | damage | Reasons |
1 | Loss of lubricant | -leakage by a gasket and guards - Burns in a cylinder cylinder or piston ring wear - Use of lower oil quality or low viscosity |
2 | Low lubricating oil pressure | Oil level is too low- Faulty oil-pressure indicator Pressure-relief valve stuck open -Pam damaged -Wear the main bearing and end big is too big The engine is too hot- Low-viscosity of the lubricant |
3 | Oil pressure too high | High-Viscosity Oil Faulty oil-pressure Meter Pressure-relief valve is stuck closed |
