Automobile
? Automobile is a self-propelled vehicle driven by an
internal combustion engine and is used for transportation
of passengers and goods on ground. Example bus, car,
jeep, truck, tractors, scooter, motor cycle.
? The modern automobile consists of a frame supporting
the body and certain power developing and transmitting
units which are further supported by tyres and wheels.
? Engine supplies the power, which is delivered by the
transmission system to the wheels through the clutch or
fluid coupling

Automobile engineering
? It is a branch of engineering in which we study
all about the automobiles and have practice to
propel them.

Parts of an automobile
? 1. machine portion
? 2. carriage portion

Machine portion
? Chassis and transmission
? Engine
? Electrical equipment

Chassis and transmission
? It support engine and transmission system
? Chassis include
? 1.frame
? 2. spring and shock absorber
? 3. steering system
? 4. brakes

transmission
? It transmit power from engine to wheel
? It consists of the following
? 1. clutch
? 2. gear box
? 3. universal joint
? 4.final drive
? 5.axle and differential

Engine
? 1.Full system-this system mixes petrol with air in the right
proportion to give a mixture which when burn provides a
pressure. The pressure is used to move a piston.
? 2.Ignition system-this system of the engine provides
regular spark to set fire to the mixture coming from the
fuel system
? 3. lubricating system-this system lubricates the moving
parts of the engine so that they can move smoothly
? 4. cooling system-this system with the help of water cools
the engine and prevents it from getting hot.

Electrical system
? -battery
? -dynamo
? -alternator

Body and carriage portion
? It is that portion of an automobile where
passenger have their seat or where the cargo
to be carried is placed.

Description of an automobile
? The following factor should be taken into
consideration while writing down the description
? 1.type-bus, truck etc
? 2. Capacity- Carriage capacity 5 ton , 3 ton 4 seater,
6 seater,30 seater etc
? Make-actual name alloted by the manufacturer such
as capacity HP of the engine maruti 800 have 800 cc
? Drive-4 wheel drive, 6 wheel drive
? Model-0year of manufacturer

Performance of an automobile
? When the fuel burns in the cylinder pressure
are developed, these pressure are transmitted
to the crankshaft by the piston and connecting
rod and torque is produced which set to
crankshaft in motion the torque produced by
the engine is transmitted through the drive
line to the wheels to propel the vehicle.
? The actual power delivered by the engine is
known as brake power=2pi nt/60x1000 kw
