Valve (Valve)
The size of the suction valve umbrella is made wider than the exhaust valve in order for optimal charging of new gas. Suction valve is usually made of a mixture of chromium and silicon steel and the seat portion and the tip of the valve stem so that the valve is more durable hardened.
For the exhaust valve is made of two different metals steel, for valve stem of steel that has good sliding properties and for umbrella valve of heat-resistant steel for the exhaust valve temperature can reach 800 degrees Celsius.
Per Valve (Valve Spring)
Per valve or valve spring serves to close (the valve returns to its original position) and hold the valve in position when open.
Wherever possible violence as recommended by the factory valve springs, because if the valve spring is too weak and will cause the valve to vibrate at high speed when the valve does not close perfectly, causing a gas leak that would lead to power the motor becomes sluggish.
Vice versa, if the valve springs are too strong will cause wear and tear on the valve such as camshaft drive-axles and a lever valve. And if allowed to continue lever valve (rocker arm) could be broken.
Sil valve (valve seals)
Sil valve serves to prevent the lubricant (oil) flows into the inlet or exhaust the combustion chamber. If the valve is damaged or torn seals can result into a smoky exhaust, because the lubricant was also burned in the combustion chamber or if the exhaust valve seals are torn lubricant will burn due to the heat in the exhaust.
Introduction / valve holder (Split Valve Guide)
Conductor serves as a sleeve valve or holding valve into place shaking and transferring heat to the valve into the cylinder head. The material is made of special cast iron and is mixed with copper. Selonsong wear of the valve can cause the valve position leaves the meeting and not be wasteful oil consumption due to slipping through the valve sleeve.
valve holder
Kinds of valve seat are of two kinds, namely
1 Direct was formed in the cylinder head, and may be used only on the cylinder head made of cast iron.
2 Stand-pressed ring-shaped valve on the cylinder head, the benefits can be replaced when worn rings and more durable because it is made of a hard material.
This article thus made may be a benefit to us all.
