2. ⦿A cylinder is the central working part
of a reciprocating engine.
OR
⦿The space in which a piston travels is
also known as Engine cylinder.
⦿Cylinders may be sleeved(lined with a
harder metal) or sleeveless ( with a
wear resistant coating such as Nikasil).

3. ⦿A piston is seated inside cylinders by several
metal piston rings .
⦿These piston rings are fitted around piston
outside surface in machined grooves,
typically two for compression sealing and one
to the seal oil.

5. ⦿A multi-cylinder engine
is a reciprocating, an
internal combustion
engine with multiple
cylinders.
⦿The more cylinders, the
more power .
⦿Multiple cylinders
have better torque
, efficiency and are
better balanced.

7. ⦿Inline engines have cylinders on top of the crank
shaft.
⦿They stand inline at a vertical 90 degrees.
⦿Inline engines run smooth and can provide a lot
of power. The engines, though, are longer then
any other type.
⦿. In cars today, most inline engines have small
cylinders so length is not an issue. Above all,
Honda's and many imports of today are known
for their inline 4's today. Usually I-4 or I-6 for
cars. Some marine engines have been made that
use the I-Engine type with up to 14 cylinders.
