Types of cylinder head

Types of cylinder head
There are different types of cylinder heads depending on the valve position whose usage depends on which type of engine they will be used in. Following are the types used.

* “L” Head

* “I” Head

* “F” Head

* “T” Head

The “L” Head
Pict0018in the L type cylinder head the inlet and the exhaust ports are on the same side of the cylinder block and operated by a single cam shaft

The “I”Head type
Pict0019In this type of cylinder head the inlet and exhaust valves are located on one side of the cylinder head. These valves are also operated by a single camshaft through the tappet, pushrod and rocker arm mechanism.

The “F” Head type
Pict0020In this type of cylinder head the inlet valves are located on one side of the cylinder head and the exhaust valves are located on the other side of the cylinder block. They are also operated by a single camshaft. The inlet valves are operated by the tappet, pushrod and rocker arm mechanism and the exhaust valves are operated by the tappet directly

“T” Head
Pict0021In ‘T’ heads, the inlet valves are located on one side of the cylinder block and exhaust valves are located on the other side of the cylinder block. Two camshafts are used to operate the valves, one for inlet and one for exhaust. In this mechanism the valves are operated by the tappet directly.

CAT 3208 ENGINE

Originally produced in 1975 through a collaboration between Caterpillar and Ford, the Cat 3208 diesel engine was extremely popular through its entire production run, which lasted into the early 1990s. The engine was used in heavy trucks, including tractor trailers, garbage trucks, school buses and construction equipment. The engine was also used in power plant and marine applications. Use of the engine was widespread and its performance was reliable; as a result, many 3208-equipped vehicles remain in service long after production of the engine ceased
