To create maximum engine power required complete combustion of each cylinder. If one cylinder combustion is less than perfect, then it will cause a big vibration in the engine. This is commonly referred to as machine limping.
A less than perfect combustion can be caused due to the pressure of compression one cylinder low pressure cylinders, or among its not the same. This caused the compression pressure deviation there are some components that are less working properly. It is usually caused by interference or damage to the valve and valve seat, piston and piston ring, cylinder, cylinder head, cam shaft (camshaft), and valve mechanism.
Common valve has no cracks at all, causing leaks and fuel blended in with the rest of the combustion will be out. This happens because the cradle and valve (valve and valve seal) is not suitable anymore. It is also very influential towards the compression pressure occurs on a machine. Especially when there is a mismatch between the valve and the cradle, good position, nor does it work. It will give rise to pressure of compression is not as expected.
This mismatch can be:
1. The valve Gap is not the same
Slit valve is entered is not the same result in the insertion of the gas or fuel with air into the cylinders at a time when the suction is not the same step size. This will cause the compression pressure is not the same as well. Next followed by combustion pressure is not the same, thus causing the machine to vibrate or limping. These symptoms will be seen at time steps of compression, nor the effort.
Exhaust valve gap is not the same will cause the exhaust gas between the cylinders become uneven. When the gap is too big, it will cause the gas when inmates step waste. The cause of the smoke flue is open when the shaft was at its dies down or while moving to the point of death.
In addition, former gas which is still this pressure would hamper the process of flushing. This means that the intake of gas suction during step be reduced and pressure of compression or combustion will also be reduced. As this happens only on one cylinder only so the symptoms immediately visible limp. Machine Symptom machine limping will also arise when the exhaust valve gap on one of the cylinders is not the same, and the next will cause gas leaks at the time step compression and step work.
2. The lip of the valve and the valve holder is on fire
When the leaves of the valve or the valve surfaces intersect holder valve holder valve, or burn some lip valve will not close tightly cradle. When this happens on one cylinder only then will cause the onset of symptoms is also limping machine.
3. Weak valve Springs
Valve spring weak which will result in the entry of the easy valve lip shit and will occur leaks. This shit is usually charcoal carbon remnants. When this happens on a single cylinder engine symptoms then just limp will soon arise.
