Engine lubrication as blood flow in humans

Task engine lubrication system for the engine and the cooling elements and the removal of impurities and sediments formed outside the motor.

Pritisak oils is one of the main parameters for the diagnosis of engine. Kod veoma istrošenih motora i motora sa velikom kilometražom, pritisak oils is usually lower and increases the slower speed as the engine heats up.

It is important to check the pressure only when the engine is already hot, because the cold oil denser, What can you wrong results. Većina vozila nema merač pritiska oils u setu, is required for diagnosis of external pressure gauge. This is a must for every professional workshop car.

Practice shows that the quality of the engine oil has a crucial impact on the durability of the engine. Under no circumstances should you save money by extending the mileage between oil changes. Especially when the car is mainly used in, oil age faster.

Visoke parametre ulja zahtevaju motori sa turbo punjačem. Turbine itself is very thermally loaded component. For motors of this type, remember that after a long drive cool drive unit before the turn off. otherwise, turbo compressor, heated to high temperatures, causing the oil combustion and soot formation, which would interfere with the rotating elements of the turbocharger. Usually this is the beginning of a process of destruction turbocharger, which often happens with turbo diesels.

Lubrication system does not require special care of you. It is sufficient if a regular oil and filter change, ako je automobil stajao i motorno ulje se ohladilo dati motoru vreme da ase zagreje , do not make the engine immediately in the high revs and let it cool down after a long labor. These are rules which respect extends the life of the entire motor.

indicator oil

Oil pressure warning light on the older models were included only when the pressure falls below the minimum. However, in technically advanced vehicle lamp can give different messages. Symbol oil filler that bright red means the pressure drop of oil. Sometimes it is accompanied by a beep, you must immediately shut down the engine. Symbol oil that is yellow (or orange) may indicate that the oil level is too low, is not necessary to immediately shut down the engine.

Engine lubrication system

Lubricating oil engines are taken out of sump oil over the so-called. site. The hose continue to the oil pump that runs directly from the motor shaft or through gears (eg. chain). At the output of the oil pump is a valve that maintains the correct pressure. When the oil pressure increases with engine obretajima, excess oil returns to the oil pan. The oil under pressure flows through the filter and goes on to the lubricated elements. first, the crankshaft bearings, cylinder liner and a cylinder head. Chapter lubricated elements such as camshaft, push rods and valve guides. Depending on the solution, an oil pressure sensor is located on the pump or close to the head. So, in some models, oil pressure warning light goes off when the starter is started, and in the second, just a minute after the engine.

bearings

These are the components located between Sue crankshaft and the connecting rod. Their work is possible due to the existence of oil pressure, which does not allow direct contact elements which cooperate. failures: loss of lubrication. Usually preceded clear zvuk.Rešenje problems: remont motora.

oil pump

Provided the correct oil pressure in the system for lubrication. failures : increasing the pump gap the lower the pressure lubrication. Symptoms may be the warning lamp for oil pressure at the hot engine when idling. The solution of the problem: Usually the oil pump is substituting new.

Oil filter

Separates dirt circulating in the system for lubrication. failures: time filter gets dirty. It is worth mentioning that sometimes filters vary slightly depending on the vehicle. The solution of the problem: Filter strogo menjati kada se menja i ulje u motoru.

crankcase oil

This is a container from which the system draws fresh lubricating oil. failures: typical for this element of the mechanical damage caused due to the impact of the barrier. Occasionally there is a leak from the seal between the sump and the engine. Oil drain plug can be damaged. The solution of the problem: Damaged container can be welded or replaced by a new. Leaks are removed sealing.

The pressure sensor

This is a very important element that monitors the oil pressure in the system. failures: broken sensor may have a short, što rezultira da indikator pritiska ulja konstantno svetli. However, engine indicator light may not be used (This could mean a serious engine failure). The solution of the problem: Replacement sensor oil pressure new.

Turbine

Turbo charger is lubricated and cooled by the same oil as the entire engine. failures: wear turbocharger leads to the entry of oil into the intake and exhaust systems. Decision errors: it is usually possible repair of the turbocharger, and in extreme cases it must be replaced.
