Mechanics

* The element responsible for converting chemical energy of fuel ( petrol , diesel , alcohol ... etc) into mechanical energy is the "motor".

* Motor is four times:

1 .- Time ADMISSION: Enters the fuel ( air + fuel) the engine.

2 .- Time COMPRESSION: fuel is compressed .

3 .- Time EXPLOSION: the spark plug and explodes the fuel to expand.

4 .- Time ESCAPE: gases, and burned , they stand out from the tailpipe.

* A "system" is a set of elements that are aimed at a mission ( cool , damp , direct ..., etc)

Power System:

Mission: To introduce fuel (air + fuel) the engine.

Main Element : carburetor

Electrical System: It is divided into four circuits.

* Circuit power :

Mission: To produce the spark plugs

Main Element : Coil

* Load Circuit :

Mission: To charge the battery of the energy the car uses .

Main Element : in most vehicles is the "alternative", but others carry a " dynamo "

* Starting Circuit :

Mission: To help the engine to start when standing

Main components: the starter

* Light Circuit :

Mission: To ensure the energy needed by the rest of the automotive electrical components

Main Element : None

The four " channels "of" power system " of a car , have one thing in common is the battery.

Inside the battery, a liquid called electrolyte which consists of distilled water and sulfuric acid.

The battery maintenance consists of filling of distilled water only when, looking inside , the electrolyte is low and also cover the battery terminals (positive and negative) with grease or petroleum jelly, is tuned to avoid .

Lubricating System:

Mission: To lubricate the engine parts that are not based (cold engine)

Main elements: the letter, which is the shell which houses the oil.

Question : What should be the engine to change the oil? ... HOT

Question : What should be the engine for measuring the oil level ? ... COLD

Refrigeration system:

Mission: To cool the engine

Main elements: the coolant ( water plus antifreeze)

Question: Where is cooled coolant ? ... THE COOLER

Question : Where do you measure the coolant level ? ... in the glass or POT OF EXPANSION

Transmission System:

Mission: to get ( pass ) the rotation of the engine to the wheels.

Elements of the transmission: the clutch, gearbox , drive shaft and bevel differential.

Suspension System:

Mission: To prevent road irregularities are transmitted to the occupants of the vehicle

Main elements: the springs , stabilizer bars, springs and dampers

Steering System:

Mission: To guide wheels

Question: What direction is the system most used in automotive? ... ON THE RACK

Braking System:

Mission : to reduce the speed ( service brake ) or stabilize the vehicle (parking brake )

Question : on what wheels does the service brake ( foot brake )?... ON FOUR

Question : on what wheels does the parking brake ( handbrake )?... ON THE REAR

Question : What elements used braking disc brakes ? ... THE PADS

Question : What elements braking using drum brakes ? ... BRAKE PADS
