3. 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).
4. 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.
7. A single cylinder engine is a basic
piston engine configuration of an
internal combustion engine.
Single cylinder engines are simple
and compact and will often deliver
the maximum power possible within
a given envelop.
8. It often seen on motorcycles,
auto rickshaws, motor scooters ,
garden machinery , automobiles
and tractors , etc.

11. 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.
12.
13. Consider a engine containing four cylinders,
the firing order such not like that 1-2-3-4
because if we are supplying the air in
cylinder number 1, the fire is take place
inside the cylinder so for the cylinder
number 2 the air is not sufficient. So that
affects the efficiency.
So the firing order should be 1-4-3-2 or
1-4-2-3.
14. When the number of cylinders are more, the
more power will be produced but less fuel
economy and vice versa.
It’s not all completely correct, in some case
a multi cylinder engine can have a better
fuel economy as compared to a single
cylinder engine, it depends on the capacity
of the cylinders and the size of valves and
how much they allow the fuel and air
mixture( In S.I engines or petrol engines) or
air for diesel engines.
16. The engine types are usually
used in the following order,
depending on the number of
cylinders: I-4, V-6, V-8, V-10,
V-12, W-16.
17. Flat engines are called flat because that is
exactly what they are. The cylinders lie flat.
Half of the cylinders are located on one side
of the crank shaft and the other half on the
other side.
The advantage to having your cylinders
horizontal is that the engine can be placed
lower in the car. This makes the car more
stable because of a lower center of gravity
18.
19. 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.
20.
21. The cylinders are arranged in a V pattern.
V-8's and V-6's engine types exist today in
many American cars and trucks.
The cylinders are located on oppsite sides of
the crank shaft and are elevated up a varying
amount of degrees depending on the
manufacturer.
The V-type engine is known for using a
pushrod valve system. Usually V-6, V-8, V-10,
and V-12.
22.
23. In W-type engines, the arrangement of
cylinders are of W shape.
W-Type engines are found in few cars.
W-engine types work well for a large number
of cylinders because everything becomes
more compact and shorter. Though, they are
more compact, the disadvantage is that they
are hard to fix and more expensive to repair.
24.
25. Wankel engines are also know as rotary
engines.
Wankel engines are completely different
from any other type of automotive engines.
It does not have pistons.
Rather a single triangular rotor spins around
a peanut shaped chamber. The triangular
rotor is a special type of triangle also known
as a Reuleaux triangle. This triangle has an
equal diameter relative to the center at all
times.
26. . The shape it is based off of an equilateral
triangle. The reason this type of triangle is
necessary is to ensure a seal during the
triangles rotation at the center of the
housing. There is a single straight shaft
through the center of one of these engines
that serves the purpose of a crankshaft in an
Otto cycle engine, Otto cycle is the 4-stroke
cycle in a regular piston engine. Wankel
engines are found in Mazda RX-7's and RX-8's
