It is important for a car’s engine to work properly. It reduces the friction of the moving parts of the engine against each other while the engine is running and ensures efficient operation. It controls the hot pressurized temperatures in the engine and helps to reduce them. The positive side of adding engine oil is that it cleans the dirt and residue in the engine, this ensures that the engine remains clean for a longer time and requires less maintenance for a long time. It prevents corrosion in the engine. It protects against friction and prevents friction in the engine, and does not cause the engine to malfunction.
How to change Oil in Vehicles :
Oil is filled into the engine through the filler neck located on the engine’s valve cover. From the head, oil is drained from the engine block to the crankcase through the return channels. The dipstick controls the amount of oil filled. The oil level should not exceed the lower and upper marks. The crankshaft’s helical gear drives the oil pump and distributor. Oil from the crankcase is pumped through the inlet pipe to the oil pump. The oil pump outlet is divided into two channels. One channel goes to the oil filter. The second channel goes to the pressure reducing valve of the pump. If the oil pressure at the pump outlet exceeds 6 kilograms per centimeter, the valve closing piston moves. Excess pressure is vented to the oil pump inlet. Thus, a constant pressure is maintained regardless of engine speed. In an oil filter, oil from the bottle is passed through the filter element. in the middle of the filter. Further along the channel, oil enters the pressure sensor and is directed to the engine block. There is also a safety valve here. It opens when oil cannot be forced through the filter. When the oil is too thick due to cold or the filter element is dirty. The main oil channel of the cylinder block. Oil supply to the head. From the main channel there are branches to the bearings of the main liners of the crankshaft. Further, oil is pressed into the oil channels of the crankshaft and fed to the connecting rod journals. Here, an oil film also forms between the connecting rod bearing and the crankshaft journal. Excess oil squeezed from under the shirts disperses under the influence of centrifugal force. Oil splashes hit the cylinder walls. As the piston moves down, the piston oil scraper ring removes oil from the cylinder walls. This creates some oil pressure between the cylinder and piston wall. Pressurized oil is released from cavities in the piston wall. And it is injected into the piston. Here it enters the upper head of the connecting rod, where there is a hole for lubricating the piston pin. In the head, oil first goes to one of the camshaft bearings. To form an oil film for the plain bearing. Further, oil is directed to the axis of the rocker arms, exhaust valves. Grease the center bearing. Oil supply to the inner channels of the camshaft to lubricate the cams. Then, oil from the rocker shaft lubricates the final camshaft bearing. From it, the rocker arms, which are already exhaust valves, are fed to the axis. Just like in the crankcase, oil dust, mist, forms under the valve cover, which lubricates other parts that do not have a direct oil supply. Another outlet for lubrication. It is located next to the flange of the camshaft star. This is where the camshaft stop plate is lubricated. Additionally, excess oil gets into the crankshaft. Spray and lubricate the timing chain. The oil then flows back into the crankcase. This is the valve disc O-ring. It is installed in the second groove on the valve body. Valve seals on this engine are not supplied from the factory. The valve disc washer limits the amount of oil that gets on the springs. The sealing rubber ring prevents oil from directly penetrating the valve stem through crackers. However, some oil still gets on the valve stem. This amount is enough to lubricate the legs. Excess oil flows down the tapered top of the valve guides.
When to change oil :
That’s how important the oil change of vehicles is. If every part of the vehicle is important, the oil change also has important aspects. When changing the oil in vehicles, it should be applied to the periodic maintenance program of the vehicles. Generally, oil change is done between 5,000 and 10,000 kilometers. If the car is in constant operation, oil maintenance should be done every 6 months.
