Car engine cooling system (Air and Water cooling)



In this article , we will talk about cooling system of the internal compustion engines.The high working temperatures of the internal combustion engine which are the cause of its high efficiency are at the same time a source of great practical difficulty in construction and operation. No known materials are capable of enduring continuously the high temperatures to which the cylinder, piston
and valves are subjected while at the same time retaining sufficient strength to withstand the high working loads. The maximum temperature during combustion is approximately the melting
point of platinum and the temperature even of the exhaust gases is above that of aluminium. It is thus essential that heat be abstracted from the parts enumerated above at a sufficient rate to prevent a dangerous temperature being reached, for, unfortunately, it is quite impossible to prevent heat entering the metal from the hot gases.

Automotive engine Lubrication


After you know the main engine components and engine working principle, we will discuss the secondary systems that are essential for engine operation which are:

1-lubrication system

2-cooling system (water cooling and air cooling)

3-fuel supply to engine

Each system will be discused in details

1-lubrication system:

Lubrication serves the following purpuses:

- Reduction of the resistance to relative motion between the surfaces.

- Prevention of seizure.

- Reduction of the rate of wear of the sliding surfaces.

- To carry away the heat generated by the friction.

lubrication system history:

Early engines had only elementary lubrication systems. Up to the 1920s,

some had manual pumps that were actuated intermittently. For others, up to

the 1930s, oil was fed by gravity from a tank through a pipe to the crankcase,

where it was either piped directly, or passed through ducts in the casting, to

the main bearings, the flow generally being manually regulated by a needle

valve. Alternatively, it was delivered into the base of the casting, whence it

was whipped up by the rotating cranks into a fine mist to lubricate all the

other moving parts.

All you want to know about your car engine




The petrol or oil engine, which is the source of power with which we are

immediately concerned, is a form of internal combustion ‘heat engine’, the
function of which is to convert potential heat energy contained in the fuel
into mechanical work.
Engine main components:
Cylinder: The ideal form consists of a plain cylindrical barrel in which the
piston slides


Piston: The usual form of piston for internal combustion engines is an
inverted bucket-shape, machined to a close (but free sliding) fit in the cylinder
barrel. Gas tightness is secured by means of flexible ‘piston rings’ fitting
closely in grooves turned in the upper part of the piston.


Connecting rod:The connecting rod transmits the piston load to the crank,
causing the latter to turn, thus converting the reciprocating motion of the
piston into a rotary motion of the crankshaft. The lower end, or ‘big end’, of
the connecting rod turns on the crank pin.


Crankshaft: In the great majority of internal combustion engines this is of
the double-web type, the crank pin, webs and shaft being usually formed
from a solid forging. The shaft turns in two or more main bearings (depending
on the number and arrangement of the cylinders) mounted in the main frame
or ‘crankcase’ of the engine.


Flywheel: At one end the crankshaft carries a heavy flywheel, the function
of which is to absorb the variations in impulse transmitted to the shaft by the
gas and inertia loads and to drive the pistons over the dead points and idle
strokes. In motor vehicles the flywheel usually forms one member of the
clutch through which the power is transmitted to the road wheels.


Previous parts are the main mechanical components of the engine,but in fact there are many systems which grantee that the engine is working properly like lubrication system,cooling system and many ather systems that will be discused later in details
Hey,here you are a complete set of videos describe in details all engine components:

Do you know the main components of your vehicle?



Hi all of you
Let us begin
Today we will talk about introduction to your car
Do you know what are the components of your car?
Your car is a very complicated integrated system This system is devided to many sub systems.
The main systems of any vehicle are:
1- Engine:it is the power source of the vehicle
2- Braking system: this system is responsible for stopping and decelerate the vehicle
3- Powertrain:it includes clutch,gearbox,driveline and differential,this system is responsible for transmit engine torque to the tires
4- Tires and suspension systems:responsible to develop sufficient tractive effort and braking and cornering effort and to isolate road input
5- Steering system:steering system is the main difference between road vehicles and trains
6- Body:it is the skeleton which include all previous systems and passengers or goods
Each system will be discussed in details


And now here you are your first video set
