What is the function of a cylinder head?

08 Oct 2016 - cylinder head

     Internal combustion engines generate power from fossil fuel. This process produces vast amount of heat. The purpose of many components of your auto's engine is to dissipate heat. Such is one of the roles of the cylinder head. Cylinder heads keep a car from overheating as well as house a few parts that are integral to the combustion that makes your giddyup go.


     Definition:A cylinder head is the closed, and often detachable, end of a cylinder located in a car’s internal combustion engine. It is typically found on the top portion of the engine block.The cylinder head contains such parts as valves, valve seats, guides, springs, and rocker arm supports. It also serves as a conduit for fuel and coolant. Your vehicle may have one head over each bank of  cylinders or a different arrangement.

      A cylinder is the power unit of an engine; it’s the chamber where the gasoline is burned and turned into power. (For more on what goes on inside the cylinders, see How Engines Work.) Most cars and SUV enginess have four, six, or eight cylinders. Generally, an engine with more cylinders produces more power, while an engine with fewer cylinders gets better fuel economy.

      A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels.[1] Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically castfrom aluminum or cast iron before receiving precision machine work. Cylinders may be sleeved (lined with a harder metal) or sleeveless (with a wear-resistant coating such as Nikasil). A sleeveless engine may also be referred to as a "patent-bore engine".


       A cylinder's displacement, or swept volume, can be calculated by multiplying its cross-sectional area (the square of half the bore by pi) by the distance the piston travels within the cylinder (the stroke). Theengine displacement can be calculated by multiplying the swept volume of one cylinder by the number of cylinders.
