Cylinder head
THEORY BACKGROUNDThe cylinder head sits on top of the cylinder.
It is where compression, spark and combustion take place.
It also holds the Valves and spark plug
Valves open and close to allow the air fuel mixture into the cylinder and the exhaust
fumes out of the cylinder.
Experiment
We used a precision straight edge and feeler gauge, to measure the head face surface for warpage.
We used the straight edge in six different direction and checked what feeler gauge fits in and
also used light to see how big the gap was. If the gap is too big than its no good because of the
leakage it can cause.
Also carried measuring the valve stems to see if they are worn, I used a micro meter for this.
Reflection
Today I learned what a straight edge is and how it can be used with feeler gauge
I also learned that the cylinder head is made from Aluminum.
Taking the Valves out was a mission and a half, it took forever because we had a 16 valve
engine, but I learned how to take them out properly and how to measure the stem.
