Cylinder Head
The cylinder head is a crucial component in an internal combustion engine, playing several essential roles in the engine's operation. Here’s an overview of the cylinder head and its functions: Cylinder Head: Location and Construction : The cylinder head is positioned above the cylinders and forms the top of the combustion chamber. Typically made from cast aluminum alloy for lightness and heat dissipation, though some engines may use cast iron for durability. Functions : Valve Operation : Houses the intake and exhaust valves, which are actuated by the camshaft(s) and control the flow of air (and fuel) into the cylinders and exhaust gases out of the cylinders. Combustion Chamber : Forms part of the combustion chamber where air-fuel mixture is ignited by the spark plug (in gasoline engines) or by compression (in diesel engines). Cooling Passages : Contains passages through which coolant flows to dissipate heat generated by combustion and friction. Mounting Surface : Provides mounting
