is among the problems usually encountered in the though few factor can be said to cause such incident such as overheating in the , but the overheating has its root causes which can contribute to such overheating and other problems are what we shall be discussing in this post.
The use in automobiles have little difference in their when compared to common use in domestic and small industrial purposes such the generators, and grinder movers, etc. the difference in the is that the automobile types has and pumping system to circulate the water in the , while the later has no such mechanism.
Though the major part in the engine that creates engine knock is primarily the piston and its rings due to the expansion in the chamber caused the high operating of the .
Below are some possible causes of when taken from their root;
has lots of purposes in the which cooling is among, when the is low it increases the friction in the which leads to heat and wearing of parts in dynamic arrangement in the . The insufficiency of the lubricating oil in the will create serious problem to the which may be gradual but will lead to the knock down of the , one of the signs of insufficient oil in the is the change in sound and higher operating . Since the chief causes of is the expansion of the in the chamber due to overheating.
The increase in the contributed due to insufficient oil adds to the overall operating making the possibility of overheating to be higher.
DAMAGED PUMPING MECHANISM
For the where water and oil pumping mechanisms were built in them, the damage to any of the mechanism may not be noted quickly except when a detecting means is included in the , but when there is exception to that; their damage could cause a sudden rise in the operating and leads to the and rings expansion which causes .
LOW WATER GAUGE
Another possible factor could be low water gauge, when the water in circulation in the parts of the had gone low due to evaporation or leakage it will contribute to the by causing rise in the .
Another cause of this problem could be bad piston rings which could be either made with wrong material or may be a good one but was wrongly fixed to the . If the latter is the case then other factors in the may be in their normal condition, even the may not be having overheating, while the intense speed of the could cause the wrongly fixed to break and the clearance between it and the cylinder.
When considering the manufacturing of the major property of materials under considerations are, low expansion, low malleability, strong hardness, low thermal conductivity and lighter weight, for this reason pistons were made with alloy of aluminum and magnesium to be able in meeting these required properties, but when the wrong is used in the manufacturing of the , it leads to easy expansion of the which in turn forces the rings to the reciprocating in the chamber.
These were the list of known possible causes of , but in the case of personal experience concerning this post, the comment box is open for your contribution and responses to others contribution.
