3. What is Automobile?
A self-propelled passenger vehicle, which is used for land transport and usually
consists of four to eight tires & is powered by an internal combustion engine or an
electric motor. The branches of engineering which deal with the manufacture and
technologies of automotive vehicles are known as automobiles engineering.
Today automobiles play a majors role in our lives, cannot be imagined without the
luxuries of the modern world. The automobile is used for both passenger and goods
transportation, so it serves as a lifeline for humans. An automobile is a vehicle that is
not controlled by humans but controlled by humans.

6. Engine
 An internal combustion engine (ICE or IC engine) is a heat engine in which
the combustion of a fuel occurs with an oxidizer (usually air) in a combustion
chamber that is an integral part of the working fluid flow circuit. In an internal
combustion engine, the expansion of the high-temperature and high-pressure
gases produced by combustion applies direct force to some component of the
engine. The force is typically applied to pistons (piston engine), turbine
blades(gas turbine), a rotor (Wankel engine), or a nozzle (jet engine).
 This force moves the component over a distance, transforming chemical energy
into kinetic energy which is used to propel, move or power whatever the engine
is attached to. This replaced the external combustion engine for applications
where the weight or size of an engine was more important.

7. Some Part of IC Engine are:-
 Piston
A piston is a disc or short cylinder fitting closely within an
engine cylinder in which it moves up and down against a liquid
or gas, used in an internal combustion engine to derive motion,
or in a pump to impart motion.

8.  CrankShaft
A crankshaft is a mechanical component used in a piston engine to
convert the reciprocating motion into rotational motion. The crankshaft
is a rotating shaft containing one or more crankpins,that are driven by
the pistons via the connecting rods.
The crankpins are also called rod bearing journals, and they rotate
within the "big end" of the connecting rods.

9.  Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a
cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another
(compatible) toothed part to transmit (convert) torque and speed.
Two or more meshing gears, working in a sequence, are called a gear train or
a transmission.

10.  Clutch
A clutch is a mechanical device that engages and disengages
power transmission, especially from a drive shaft to a driven
shaft.In the simplest application, clutches connect and
disconnect two rotating shafts (drive shafts or line shafts). In
these devices, one shaft is typically attached to an engine or
other power unit (the driving member), while the other shaft (the
driven member) provides output power for work.
