Aluminum offers lighter weight at the expense of strength, hardness and often cost. However, with care it can be substituted for many of the components and is widely used. Aluminum crank cases, cylinder blocks, heads and pistons are commonplace. The first airplane engine to fly, in the Wright Flyer of 1903, had an aluminum cylinder block. [1]
It was a 60 degree V-12 of 1,650 cubic inch displacement with cylinder bore and stroke matching the Merlin aviation engine, using an aluminum block and head; dual overhead camshafts, and four valves per cylinder. The intention of this design was to help Ford break into the anticipated large market for aircraft engines.
Nash supplied Healey's company with the powertrain components: the Ambassador's inline six-cylinder OHV 234.8 cu in (3.85 L) engine and three-speed manual transmission with Borg-Warner overdrive. Healey fitted a lighter, higher-compression aluminum cylinder head (in place of the cast-iron stock item) with twin 1.75-inch (44 mm) SU carburetors .
Most automotive engines use aluminum pistons that move in an iron cylinder.The average temperature of a piston crown in a gasoline engine during normal operation is typically about 300 °C (570 °F), and the coolant that runs through the engine block is usually regulated at approximately 90 °C (190 °F).

This is also common for motorcycles, and such head/cylinder components are referred to as barrels. Some engines, particularly medium- and large-capacity diesel engines built for industrial, marine, power generation, and heavy traction purposes (large trucks, locomotives, heavy equipment, etc.) have individual cylinder heads for each cylinder ...
A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.
By 1956, Idra was seeking to export its die-casting machines outside Italy. [4] By 1971, an Idra OL-1200 S machine was being used to cast motor components weighing 7 kilograms (15 lb) for Porsche cars.
