The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long.
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
A simple three-into-one exhaust for each cylinder bank provides uniform scavenging, since the engine is effectively behaving like two separate straight-three engines in this regard. Primary reciprocating plane and rotating plane imbalances are present due to the distance along the crankshaft between opposing cylinders.
Some engines have used a V-angle of 180 degrees (the same angle as a flat engine), such as several Ferrari V12 engines. [7] [8] At the other end of the scale, the 1922-1976 Lancia V4 engine and the 1991–present Volkswagen VR6 engine use V-angles as small as 10 degrees, along with a single cylinder head used by both banks of cylinders.
The most common crossplane crankshaft for a 90° V8 engine has four crankpins, each serving two cylinders on opposing banks, offset at 90° from the adjacent crankpins.The first and last of the four crank pins are at 180° with respect to each other as are the second and third, with each pair at 90° to the other, so that viewed from the end the crankshaft forms a cross.
The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks: in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine (Benz Contramotor) was built in 1897 by Karl Benz. Flat engines have been used in aviation ...
