ICE Structure The base of a reciprocating internal combustion engine is the engine block, which is typically made of cast iron or aluminum. The engine block contains the cylinders. Water-cooled engines contain passages in the engine block where cooling fluid circulate (the water jacket). Some small engines are air-cooled and instead of having a water jacket the cylinder block has fins protruding away from it to cool by directly transferring heat to the air. The top part of the engine is the cylinder head. It contains the camshaft, the valves and their moving mechanism. At the bottom, the crankshaft rounds in the base of ICE, inside the oil pan, where usually the oil is saved. Click on the icon to watch the video.
