2. Engines are mechanisms
capable of transforming a type
of energy (electrical,
combustion, etc.) into
mechanical energy. This
transformation allows the
performance of work that
makes a system or machinery
work, all of this is done thanks
to its parts, which are all very
important.

10. The oil pan is vital, though simple, part of your
engine’s lubrication system. The oil pan keeps
that oil contained in the lubrication system, so it’s
important that the oil doesn’t leak out. Since it’s a
metal part attached to another metal part, there
is a gasket between the oil pan and the part of the
engine it attaches to

11. Combustion Chamber is the area within
the Cylinder where the fuel/air mix is
ignited. As the piston compresses the
fuel/air mix and makes contact with the
Spark Plug, the mixture is combusted and
pushed out of the Combustion Chamber
in the form of energy.

12. The intake manifold in a car is the part of the engine that
distributes the air flow between the cylinders. Often an
intake manifold holds the throttle valve (throttle body) and
some other components.
The intake air flows through the air filter, intake boot
(snorkel), then through the throttle body, into the intake
manifold plenum, then through the runners, and into the
cylinders.

13. The exhaust manifold is generally
simple cast iron or stainless or steel
units that collect engine exhaust gas
from multiple cylinders and deliver it
to the exhaust pipe. Its construction
is the same as the inlet manifold.

14. Inlet and exhaust valves are used to
control and regulate the charge (or air)
coming to the engine for burning and
exhaust gases going out from the cylinder
respectively.
ntake valves are connected to the intake
manifold and exhaust valves are
connected to the exhaust manifold. Both
intake and exhaust manifolds are
discussed above

15. A spark plug is a device for delivering
electric current from an ignition system
to the combustion chamber of a
sparkignition engine to ignite the
compressed fuel/air mixture by an
electric spark while containing
combustion pressure within the engine.

16. A connecting rod is the part of a piston
engine that connects the piston to the
crankshaft. Together with the crank, the
connecting rod converts the reciprocating
motion of the piston into the rotation of the
crankshaft. The connecting rod is required
to transmit the compressive and tensile
forces from the piston.

17. The main functions of piston rings in engines are:
•Sealing the combustion chamber so that there is minimal
loss of gases to the crank case.
•Improving heat transfer from the piston to the cylinder
wall.
•Maintaining the proper quantity of the oil between the
piston and the cylinder wall
•Regulating engine oil consumption by scraping oil from the
cylinder walls back to the sum
