3. • Automotive system is about the design manufacturing and operation
of cars , motorcycles, trucks and other automobiles there are lot of
subdisciplines within automotive system and there are many things you
work on when it comes to an automobile.
Automotive can be anything moving on the wheels but automobiles
generally refers to car, i think the four wheeler. "Automobile" literally
Means something that can move itself. Automotive refers to anything
Related to an Automobile.
WHAT IS AUTOMOTIVE SYSTEM

4. • Safety:
• Work on the safety aspect and assessing various crash scenarious whether
it be on the computer to doing actual crash testing cars needing to meet
certain standard to protect the driver and passengers. The frame of the car
would have to be designed properly such that energy from a crash is
absorbed or moved away from the driver.
SUBDISCIPLINES;

5. • Performance:
• There's performance and analyzing how fast the car can accelerate how
quickly you can come to a complete stop which of course is important
and more.
How quickly can it come to a complete stop:
Vehicle dynamics;
-braking , handlings , steering, etc.

6. • Fuel and air system:
It is designed to supply the correct amount of fuel mixed with correct amount
of air to the cylinder of the engine.
Stores the fuel of later use. Delivers fuel to a device that controls the amounts
of fuel going to the engines.
Collects and cleans the outside air. Delivers outside air to the individual cylinder.
Changes the fuel and air ratio to meet the needs of the engines during
Different operating speed and condition.
TYPES OF AUTOMOTIVE SYSTEM:

7. • Exhaust system:
Direct toxic exhaust fumes away from the passengers compartments.
Quiet the sound exhaust pulses.
To burn or catalytes polutants in the exhausts.

8. EMMISION CONTROL SYSTEM;
Positive crankcase ventilation system: reduces hydrocarbon emission and
prevents the pressurised the vapour for escaping the engines and cutering the
atmosphere.
Evaporative emission control system: it dranles the fuel vapour from the
fuel system.
Exhaust gas recirculation system: this system introduces exhaust gases into
the intake air reducing the chances of forming NOx during combustion.
Air injection system: to introduce fresh air into the exhaust stream to cause
minor combustion of the hydrocarbon in the engines exhausts.

9. Heating system;
The main component of an automotive heating system are the heater core,
the heater control value the blower motor the fan and the heater and defroster
ducks. The heating system works with the cooling system and converts the heats
from the coolent circulating inside the engine to hotair which is blown into the
Passengers compartment heater pipe transfer the hot coolent from the engine
to the heater control valve and then to the heater core in it.

10. • AIR CONDITIONING SYSTEM:
A AC system is designed to remove heat from the passenger compartment
and move to outside of the vehicle.
The substance used to remove the heat from inside of the vehicles of is called
the refrigerant by changing the pressure of refrigerant by changing the pressure
of refrigerant to absorb heat the temperature and pressure of refrigerant are
kept low.

11. • The most common ways to coolent and engine is to circulate a liquid coolent
the passage in the engine block cylinder head.
A typical coolent realise on a water pump circulate the coolent through the
system.
The pump typically driven by the engine the coolent is the mixture of water
and anti-freeze.
Now this heat picked up by the coolent is send to the radiator which transfer
the coolent heat outside the air as the coolent flow through the tubes.
COOLING SYSTEM:

12. • LUBRICATION SYSTEM:
Motor or engine oil is the fluid used to lubricate the engine. The oil store in
the oil pan bolted to the bottom the oil pan is also called the crank case or
oil sump. When the engine is running and oil pump draws the oil from the
Oil sump and forces it through the oil galleries.
Oil from the pan passes through an oil filter before moving through the engine
the filter removes dirt and metal particles from the oil.

13. • CHARGING AND STARTING SYSTEM:
The vehicles starting and charging system cranks the engine for starting charges
the vehicles battery and provides the electrical power for engines controls
lights and eccessories key components of the starting and charging system
includes the battery which stores the electrical energy the starter motor
which cranks the engine the alternator which charges the battery and power
the vehicle electrical system and battery cables to connects the battery mal-
functions can cause abnormal noises dim lights discharged battery no crank
Condition and may illuminate the battery the lamps .
