Following that, engines began to combine two or three cylinders into a single-cylinder block, with an engine combining several of these cylinder blocks. In early engines with multiple cylinder banks – such as V6 , V8 , or flat-6 engines – each bank was typically made of one or multiple separate cylinder blocks.
Compared with the M78, the M328 has an aluminium cross-flow cylinder head [4] with hemispherical combustion chambers. [5] The M328 was used in the BMW 328 and BMW 327/28 coupes. [2] [3] [6] After World War II the engine was also licensed to Bristol Cars in the United Kingdom.
Although successfully used by many European manufacturers, there are potentially issues associated with engines that use Alusil blocks, namely cylinder bore scoring which occurs when there is a breakdown of the exposed silicon particles in the cylinder bore, resulting in increased oil consumption and excessive piston noise.

Cylinder bore: 83 mm (3.3 in) Piston stroke: 92.3 mm (3.6 in) Cylinder block material: Aluminium alloy, cast iron liners: Cylinder head material: Aluminium alloy, integrated exhaust manifold: Valvetrain: 4 valves / cylinder, DOHC, chain-drive, electrohydraulic fully variable intake and exhaust valve lift system: Compression ratio: Petrol: 10.5 ...
The S52 also shares more in common with the regular M52 engine than the S50 did with the M50, for example sharing the engine block (cast iron, as per North American M52 engines) and cylinder head. Unique to the S52 is a bore of 86.4 mm (3.4 in) and stroke of 89.6 mm (3.5 in) for a total displacement of 3,152 cc. Compression ratio is 10.5:1.

Cylinder block material: Gray cast iron: Cylinder head material: Cast aluminium alloy: Valvetrain: 2-, 4-, or 5-valve [4] valves per cylinder, hydraulic valve lifters, belt-driven single overhead camshaft (SOHC) Compression ratio: 8.0:1-10.5:1: Combustion; Fuel system: Carburetor or electronic fuel injection: Management
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] All-aluminum engines are rare, as the material is difficult to use in more highly stressed components such as connecting rods and crankshafts.
