Guyz i just need a small details of engine’s material, from what kind of materials is created, with percetanges or whatever !

Production automobliles going back to the 1890s have made extensive use of cast iron. If you piled up every auto engine ever produced from the 19th century through today, you would be looking at cast iron mostly, some aluminum, steel and small amounts of brass, copper, plastic, and wee bits of magnesium.
Early auto engines made use of iron especially in massive parts like blocks, crankshafts and heads. Many of today’s larger auto and truck engines are still composed of iron primarily.
Use of lighter weight materials begins with aircraft and motorcycle engines. Motorcycles until recently lacked radiators, so their engines used three basic elements; cylinders with cooling fins, a crankcase and heads. The cylinders were frequently iron and the rest, aluminum. Some car engines follow motorcycles in this respect. The Volkswagen was intended as a car for “der volk”, (the folk, or the “working poor”) so German industrialists in the 1930s insisted on motorcycle like engines for der volk.
In the 1930s, aircraft engines began making greater use of aluminum in massive liquid cooled engines. Among the first was an Alfa Romeo aircraft Diesel in V8 and V16 configurations. These engines had aluminum blocks and heads, iron crankshafts and iron cylinders called liners (not sleeves).
Beginning in 1954, this configuration was used in cars by Alfa Romeo (their DOHC hemi 4 cylinder) and by Rolls Royce with their 1958 V8. This type of engine, mostly aluminum, derives from aircraft. Alfa, Rolls and other auto builders built piston aircraft engines.)
Today, most engines are built in this configuration. Some of today’s aluminum engines have aluminum cylinders and some have iron liners.
The Alfa Romeo in the avatar photo that I use is a 2 liter GTAm race car from 1971 or 2. It has 4 iron liners cast in one piece, so they’re joined at the top where they contact the cylinder head. My 2004 Acura has a 2 liter 4 cylinder with the same type of iron liners cast in one piece.
Yesterday’s auto engines were mostly iron, but today’s most advanced auto engines have replaced massive iron components with aluminum.
Maybe someone else has something to add.

Heres a video that Eric made dissecting an engine C8-)
