The oil tubs provide compaction at the place where the gas distribution mechanism is attached to the rails and prevent the oil from entering the combustion chamber.
Despite the tremendous progress made in the development of car engines over the last hundred years, details remain exposed to intense deterioration and frequent replacement. Usually these details are called costals. The washers (or lambers of the valves) could be classified under this category if not one "but"-they are installed in a very remote location.
What do we need to do with the cap-on?
The valve is an important part of the gas distribution mechanism. Valves are the prom and prom. The upper part of any valve is located in the area where the oil mist is heavy by the constant rotation of the valve. The bottom, flat part, is located where the flattened petrol drip is permanently charged, if the intake valve is present, or in a hot exhaust environment, if the valve is a drain valve.
According to the manufacturer's recommended procedure, the replacement of the oil cap should be done on the removed cylinder head
The lubricant is vital to the normal operation of the distribution shaft, but the introduction of motor oil into the combustion chamber is highly unwelcome. Therefore, when the valve is moving up and down, the oil from the mashroom removes a kind of protective skirt, which is called a cap-cap.
How the valves of the valves work
When oil is released into the combustion chamber of the valve, the oil is mixed with the fuel-air mixture. When the mixture is flashed, the oil will be burned to form the upper part of the plate and the valve seat. This causes the valve to lose its ability to close. The same tanning remains on the top of the piston and on piston rings. All this leads to so-called incoherence, increasing engine wear and the quality of its work. In addition, the oil in the combustion chamber degrade the burning behaviour of the petrol-air mixture. Therefore, the condition of the oil tutu is very high.
Device of the cap-ream
The modern version of the saline is a rubber cap with a reinforced steel rod and an edenser spring which compels the sealing edge of the cap to the valve.
The high efficiency of a cap-pack is determined not only by the construction, but also by the material from which it is made. If an acrylic rubber or a secondary rubber is used in the production, the cap will have a high degree of compaction. The obsolete, unreinforced caps were installed on older engines, and the good "clamping" was achieved at the expense of a wide edge.
The nose of the paper caps is almost entirely dependent on the manufacturer's level of technology. Chery and BMW may have the same length of service
It is very important to know which caps are installed in the engine. First of all, because their replacement is a costly operation involving the need to disassemble the engine. Therefore, it is necessary to strictly observe the rule: to install only the original caps for a particular engine.
Causes of wear of the oil cap
The wheel of the engine shall be rotated at a speed of 500 (single) to 4,500 rpm. For one minute, each valve performs approximately 150 to 1200 clock cycles. It is clear that a very large amount of work is being done on the loft. In doing so, it is also subjected to chemically aggressive exposure to oil and exhaust gases. As a result, the rubber, from which the soft part of the cap is made, is solid, and the cap of the cap shall be worn and washed away. They will have to change sooner or later, however good they may be. However, it is not worth to think that they, like candles, need to be changed every year. The culture of production of leading automobile concerns is so high that on average, the length of the cap service is about 100,000 kilometers. However, the percentage of engines on which the caps have to be changed is very high.
Signs of wear on the shale caps
Signs of wear on the shale caps
Experienced drivers know: the emergence of sediment on the candles, the need to pour oil into the engine between the substitutions, the introduction of smoke from the exhaust pipe when the gas is pressed-all are signs of wear on the cap-caps.
The use of high-quality motor oil contributes to the preservation of the good condition of the oilseed caps
Of course, it is better to replace the oil-swap caps before visible signs of wear and tear. The late replacement of the caps results in the accumulation of coke in cylinders and the compression of the compression. Fuel consumption is increased, idle idling, power is reduced.
