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. Since the 1930s, mass ...
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.
DKW RT 250 (1952–1953) motorcycle engine. A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder.This engine is often used for motorcycles, motor scooters, motorized bicycles, go-karts, all-terrain vehicles, radio-controlled vehicles, power tools and garden machinery (such as chainsaws, lawn mowers, cultivators, and string trimmers).
In both types of engines there are one or more cylinders (grey and green), and for each cylinder there is a spark plug (darker-grey, gasoline engines only), a piston (yellow), and a crankpin (purple). A single sweep of the cylinder by the piston in an upward or downward motion is known as a stroke.
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”.
The engine block and cylinder heads were cast at Saginaw Metal Casting Operations in Saginaw, Michigan. The Generation II small-block engine, introduced in 1992 as the LT1 and produced through 1997, is largely an improved version of the Generation I, having many interchangeable parts and dimensions.
It is available in both SOHC and DOHC 16-valve versions (4 valves per cylinder). The engine features a cast iron block, and pistons with shallow crowns to save weight. The block uses a bedplate featuring a perimeter wall with transverse webbings for durability and quiet operation at high engine speeds.
These engines were built exclusively at Bupyeong engine plant and marketed as E-TEC. Like all Family 1 engines they feature a toothed belt driven valvetrain, a cast-iron engine block and an aluminum cylinder head. Most models feature Euro III-compliancy, and the 1.4 L (1399 cc) and 1.6 L (1598cc) versions employ variable intake geometry.
