POWER PLANT

Where  Is the produce  power  that’s called power plant. As automobile vehicle body the power plant is a engine.

WHAT IS THE ENGINE-:

                                   Engine is few assembly of parts who generate the power some technical process convert chemical energy to mechanical energy.

BODY

BODY

-: Body is the main part of a vehicle and it make design  depend on the chassis frame and manufacturer

ADVANTEG OF BODY-:

1-: STRENGTH --- 

                              The is must be strong enough to with stand all type  of force to which the car is subjected , which include  the weight of the car passenger  and the luggage , inertia braking and side forces. It should also be able to cope with impact  load of reasonable magnitude.

2-: AIR DRAG --- 

                              The resistance of the air  during running depends  upon the body shape  and increases  directly as  the square of the vehicle speed . the shape of the body  should be such that the air dage ig minimum.

3-:WEATHER PROTECTION --- 

                               The design of the body  must be such that the occupants  and the luggage  are protected  form bad  weather .

4-LIGHTNESS----- 

                               The body should be as light as possible  in relation  to the amount  of pace  in side .

5-:PROTECTION OF ACCIDENT ---- 

                                This is very impotent consideration in the car body design. The body must be such that  the driver is at maximum ease so that there are  last chances of the accident  taking place  due to fatigue . how ever in case  thr accident take place  the body must protect  the occupants .

CHASSIS

  CHASSIS-:-

Chassis is the main base  of a vehicle . who carrying all accessories of a vehicle all are fitted in chassis .

TYPE OF CHASSISE-: THERE ARE THREE TYPES OF CHASSIS FRSME

1-    CONVENTIONAL FRAME

2-    INTEGRAL FRAME

3-     SEMI  INTEGRAL FRAME

****CONVENTIONAL FRAMW******

-: It has two long side members and no of cross member ( depend on manufacture)  joined  together with the help of bolts and rivets. That types of frame used generally heavy vehicle.

*******INTEGRAL FRAME****

-:This frame is used now a days in most of the cars. There is no frame and all the assembly units are attached  to the body . all the function of the frame  carried out bye the body  it self.  Due to elimination of long frame  it is cheaper  and due to less weight . most economically also .  ( only dis advantage is repairing difficult.

******** SEMI INTREGRAL FRAMW*******

-In some vehicle half frame in fixed  in the front end on which  engine gearbox  and front suspension is mounted  . it has the advantage  when the vehicle is meat an accident the front frame can be taken easily to replace  the damage chassis frame. This type of frames is used in some of the European  and American car
