Description
Where is a cylinder located on?
A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber.
What is the function of cylinder head in engine?
The passages in the cylinder head allow air and fuel to flow inside the cylinder while permitting the exhaust gases to flow out of it. The passages are otherwise called ports or tracts. The cylinder head also channels the coolant into the engine block, thereby cooling down the engine components. The cylinder head uses a gasket that aids in preventing water or oil from leaking into the combustion chambers.
A cylinder head is the part of an engine that closes the upper ends of the cylinders. In an internal combustion engine, the cylinder head sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape. The head can also be a place to mount the valves, spark plugs, and fuel injectors.
What is in a cylinder head?
A cylinder head contains intake air, exhaust, and oil passageways. One of the functions of a cylinder head is cooling the engine. The head achieves that using two main methods; water or air. Water-cooled heads are the most popular, and many modern engines are of this type.
Main function
The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled engine, the walls of the cylinders are exposed to the airflow, to provide the primary method of cooling to the engine.
Can a cylinder head be repaired?
Actually, Repairing a cracked cylinder head always involves a certain amount of risk, but when done properly is usually much less expensive than replacing a cracked head with a new or used casting. Most small cracks in cast iron as well as aluminum heads can be repaired by pinning.
