Wear and tear is a normal process of engines. Mild wear and tear will not cause big performance dips or problems. It is only when the wear is serious that you need to get the vehicle checked and repaired without delay for continued performance. Cylinder sleeve and liners are some of the least wearing parts of an automobile engine but it does and when that happens, you will experience a serious dip in the way it responds to your throttle inputs. Liners and sleeves are meant to last a lifetime, but that is not always the case. Let us find out the real culprit behind it.
Wear Due To Friction
When two mechanical parts move against each other, there is bound to be some friction. Automobile engineers deal with that by using lubricants. Grease and oils reduce friction but do not entirely eliminate it, as a result there will always be loss of metal parts from the pistons and cylinder blocks. Eventually the wear becomes significant. Cylinder sleeves are made of cast iron and play a crucial role in transferring the power from the engine to the piston rod. A faulty unit should be replaced to maintain integrity of the power train.
Combustion Side Effects
The combustion occurring inside an engine block produces sulfur, which is a potent acid. Sulphur can corrode metal. To counter the effect of sulfur, cylinder oil is used which is alkaline in nature. When the output of sulfur is more than what alkaline content in cylinder oil can manage then the overall effect is an overwhelming amount of acid in the engine. Corrosion within the sleeves become even serious with presence of water in fuel or air.
Microscopic Scuffing
The cylinder sleeve and liner depends on a coat of oil and lubricant to perform without any glitch. But when lubrication decreases there are minor scuffing caused by microscopic welding of the ring which detaches from the cylinders and increase the rate of wear.
There may be other reasons why cylinder parts wear and tear but there are also others. To know more about sleeve and liner issues talk to an automobile engineer at the earliest.
