SIGNS OF BAD OR IN AN
An such as or requires a < for the optimum performance of the .
The function of the piston is to compress the air- fuel mixture in the combustion chamber and help to carry the crankshaft to revolve at it axis through the help of the power stroke coming from the combustion chamber of the engine. The piston also helps to expel the burnt air-fuel mixture in the chamber and delivers it to the exhaust channels. The serves as the major part of the , due to the fact that its reciprocating action in the chamber is what causes the to rotate and hence, creates the whole rotational motion of the .
Mechanically, the type and size of the and its rings in an will greatly determine its overall performance including its speed and torque. For this reason, many manufacturers had come up with several in a way of optimizing the performance. These led to the development of multiple pistons and cylinders in an . Also it led to the development of different shapes in the such as the V-shape design, the Y-shape design, the H-shape design and the O-shape design, etc. these were used by manufacturers to obtain the desired performance and size needed for any purpose the will be meant to serve.
The majority of the internal combustion engines are now used for heavy duty jobs and for moving industrial machines due to the increase in the size and number of pistons in the engines modern designs. Some modern internal combustion engine can have about 6 to 12 pistons arranged in their various cylinder walls with their various combustion chambers, such engines have their piston reciprocating movement timed and controlled such that at specific angle of the crankshaft there would be a such that the keeps obtaining momentum from the various power strokes of the pistons.
Meanwhile, the actual function of the piston rings is to help in closing the gap in the clearance created between the and the cylinder wall is reciprocating inside, though the rings are meant to close the clearance; it is not permitted to close it completely in such manner that would affect the reciprocating action in the cylinder wall rather they are meant to great small allowance for on the cylinder wall.
When an internal is having < its performance in power output will be high as well as other factors in the performance, but when the reverse is the case the following could occur and it could also serve as signs when the existing have become faulty, for an in such condition the following could happen to the ;
REDUCED POWER EFFICIENCY
As mentioned earlier that the power output of an greatly depends on the size, type, and a number of and the . If an was performing at an efficiency of 98% and later its efficiency drops to 80% the trace to such drop in the power output could be attributed to the and the . Research has also shown that even some new due come with low efficiency in power output which can be attributed to the high allowance between the and the cylinder wall.
The major cause of the power drop could be as a result of the excess wear of the such that they now create excess allowance between the cylinder wall and the , in such situation some of the air-fuel mixture sucked into the chamber for and would escape into the zone through the excess gap between the cylinder wall and the , such that the pressure built of the mixture during is greatly affected hence, when the takes place the power release to push the downward would not be the same, thereby affecting the overall performance.
Just as the excess allowance between the and cylinder wall affects the , the lack of allowance between the and the cylinder wall also affects the performance. When good calculations were not done while determining the size of and the for an , it could lead to having and with very close clearance in the cylinder wall; such that any expansion of the as a result of rising in during its power strokes and reciprocation actions could close the existing allowance completely thereby causing excess wear on the cylinder wall and the due to the excess friction that has existed in the , this action causes the cylinder wall to increase and hence affecting the whole operating . A situation like that causes easy to damage to the cylinder walls and could lead to the breaking of the , it can also contribute to excess noise in the .
EXCESS SMOKE FROM EXHAUST
When the allowance that exists between the and cylinder wall is too much, the that is pumped into the cylinder wall just below the which is meant to lubricate the cylinder wall will find its way into the chamber through the escess allowance, and this occurs the will mix with the air-fuel mixture in the chamber and they will be burnt together, such a situation will cause high release of carbon monoxide in the form of black smokes which will show its evidence from the exhaust pipe or hole.
The knocking of an is a situation where the comes to a sudden stop without any prolonged faulty signal and the at that moment refused to turn or start again. The major problem of this situation can be pointed to the expansion in the or the or both of them.
When the allowance in the cylinder is too close such that an increase in the of the could close such allowance it means that whenever the operates and reaches such the allowance will close such that the cannot be able to reciprocate in the cylinder wall, the result will cause the sudden shutdown of the , and as long as the at that moment has not reduced the wouldn’t be able to move in the cylinder, thereby making the turning of the impossible or difficult and any forceful action to turn the will cause more damage to the and the cylinder wall, so the best action is allowing the to come down before trying to turn it again.
With these few points, it is important you understand your to avoid unnecessary damage to the and creating more cost of maintenance for the .
