Description
Intake and Exhaust Ports
The intake and exhaust ports are part and parcel of the cylinder head. The intake manifold function is to channel air through the passages in the cylinder head and into the combustion chamber.
After the combustion process, the gases produced must be removed. That is the role played by the exhaust. The exhaust ports connect to the exhaust manifold to drive out the gases. This prevents a buildup of internal pressure, which would otherwise result in an explosion.
Cylinder Head Valves
In an engine, valves close and open to let in or block the entry of air and fuel into the combustion chamber. Each cylinder in an internal combustion engine has two valves- the intake valve, which is usually bigger and a smaller exhaust valve.
Several components hold and control the working of cylinder head valves. The parts are explained next.
Valve spring
the valve spring helps keep the valve shut. Depending on the design, a valve spring may comprise one or two different springs, sometimes even three. The triple spring construction is mostly found on performance engines where a high level of reliability is required.
Valve spring retainer
as its name suggests, the spring retainer is the part that helps to maintain the spring position. It mounts on the spring’s top end. The valve spring retainer is usually made from steel.
Retainer lock
the retainer lock is the part that lies between the spring retainer and the tip of the valve. The pressure or force exerted by the spring helps to hold the lock in place and the components intact.
Valve seal
mounted on the valve stem, and just under the spring, the valve seal prevents cylinder head leaks. It keeps oil from getting into the intake and exhaust passageways and ensures the proper working of these cylinder head parts.
