While replying to the recent trending search term of causes of damage in generators, I found out that majority of our previous posts relating to had not been read by some of them. So to understand better, it is good one go through the previous posts on this topic of the and its rings after reading this one.
The is a major part of an , of which; if it is not there the will not function irrespective of how good all the parts of the may be. It is like a heart of every human which leaves the human dead once it stops working. Therefore, the is essential in an .
It is the that plays the role of , suction, and smoke exhausts so without it there will be no operation. The is located in the center of the chamber, it has a connecting rod that links it with the , the reciprocating motion of the in the chamber causes the to rotate, it is a case of transfer of motion from a reciprocating motion to a rotational motion of the . Hence, if does not rotate, the will not also rotate.
On the other hand, are sets of two, three or four rings usually worn around the . The functions of the include;
- Ensuring proper of the air-fuel mixture in the chamber.
- Ensuring proper evacuation of the burnt content (carbon monoxide) in the chamber.
- Helping to exist at the clearance between the rings and the walls of the chamber’s cylinder, by trapping the lubricating oils coming from the crankshaft’s rotation.
- Protect the chamber from excessive heat by creating a clearance between the cylinder wall and the .
- Reduce the wear and tear ratio in the chamber.
- It can help to prevent damage to either the or the cylinder wall. And Etc.
These and more are the functions of , however the rings due undergo frequent damage more than any other little parts of the located in the chamber and the reason is because of the vital roles they play to prolong the lifespan of the by ensuring that little or no damage is done to the entire system.
It is vital to note that any time an knock occurs definitely the have been damaged and must be replaced. Before an knocks the will first expand due to the increased of the , so when the expansion has reached the clearance gap between rings and cylinder walls the rings will stick to the cylinder walls and cause the to stop its reciprocating motion thereby shutting the down, which is when we say has occurred.
Besides overheating, other factors can cause damage and such include incorrect fixing of the , using the wrong size of for a particular , and others.
Having known some factors that usually damage the . Let us discuss that of the itself.
The piston as said earlier is vital, and may not develop a fault or get damaged easily if everything in the engine were in other. In other words, before piston got damaged something else was not in order in the . If an is having overheat, it can lead to which may damage both the and its rings or the rings only depending on how serious the knocking may be. If an used in the chamber is longer than it was meant to be in the chamber, it can be hitting on the surface of the to cause . Also, if the was made with the improper material it can be expanding in an unusual way to cause frequent and eventually got itself damaged. These and other factors are what makes the to be damaged.
