In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...
VR5 and VR6 engines are very compact and light, having a narrow V angle which allows a single cylinder block and cylinder head. These engines use a single cylinder head so are technically a straight engine with the name "VR" coming from the combination of German words “Verkürzt” and “Reihenmotor” meaning “shortened inline engine”.
De Dion-Bouton engine with monobloc cylinder heads, but cylinders separate from crankcase c. 1905 [1]. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later.

Siamesed cylinders are engine cylinders arranged in such a way that they have no channels between them to allow water or other coolant to circulate. [1] [2] Cylinders are generally arranged in this manner when the engine block is of limited size or when stability of the cylinder bores is of concern, such as in racing engines. [3]
Cylinder liners (also known as sleeves) are thin metal cylinder-shaped parts which are inserted into the engine block to form the inner wall of the cylinder. [4] [5] Alternatively, an engine can be 'sleeveless', where the cylinder walls are formed by the engine block with a wear-resistant coating, such as Nikasil or plasma-sprayed bores.
During that time, the Model A and AA engine cylinder block (part number A-6010), went through various external and internal changes. [15] [16] The Model A was replaced by the 1932 Ford Model B, with an updated 4-cylinder engine, and by the 1932 Ford Model 18, with its new Ford V8 engine. [15] [16]
The World Gasoline Engine is a family of straight-4 piston engines, based on the Global Engine Alliance design. Three engines have been produced: a 1.8 L, a 2.0 L, and a 2.4 L. The initial design of the engine block and cylinder head was handled by Hyundai as part of the Global Engine Alliance.
