Reasons of having air pressure in the engine of diesel motors: 1-When the fuel ends , 2- When the clean of filters and mazaout -water seperator. 3- If there is any crackle or laxity in the system Motor have air pressure Motor having air doesnt work Oiled air filter used in diesel motors clean as washing the gasoil.Heating plug is used in cold weather for working easily of diesel engines. In diesel engines when press the starter of vehicle starter of the motor turns but if motor doesnt work the reason of it will be plugged of fuel filter.
LUBRICATION SYSTEM Aims: Prevent getting the engine oiled,erosion between parts which occurs with friction, to fiil the blanks and supply imperviousness
Parts: 1- Sump: Relax the oil ,cool down an be depot for oil 2- Oil Pump: Sen oil to system as pressure 3- Oil dipstick: To show oil level 4- Oil gauge: Measure the oil pressure as electirical and sent to oil pressure gauge
5- Oil pressure gauge :Show
the oil pressure in the systems Working: Oil pump also begin to work when the engine begins to work.Oil in carter case send to oil lines filtres from oil filter. Works end oil turns back to carter case from return pupils. While oil circulate in the system clean the dirts and helps cooling. When enter the carter case leave the dirties get cool and be ready dor going pupils again. Engine Oil Prevent erosion between parts which occurs with friction and also clean and cooling. 20 x 50 oils used in engines. It must be changed in determined times in guide book. It controls ın the daily maintanence. Engine should be hot while changing. Oil Filter Supply the oil cleaning. It must be changed in determined times in guide book. In every two oil changes filter must be changed as a rule. When the oil lamp is lightened motor must be stopped. Oil Dipstick Show oil level .Oil level must be between 2 lines in the chekings. Oil Gauge To send oil working pressure to oil pressure gauge. If the cable is split off current can not be transmitted. Oil Pressure Gauge
To show that lubrication
system of engine works or not to driver.Some
vehicles have manometer. But all the vehicles have
red oil light . If there is danger about oiling red
light is lightened. Also light in cater case. |
