THE CAR ENGINE

                                   
                  THE CAR  ENGINE....

Ever opened your car bonnet to check on the oil level then realized that apart from the dip stick and the engine there is nothing else you know in that car,but its obvious every body knows the engine, but how many know the workings of their Car engine.

Very few understand what goes on in their car ,the workings of different car parts that work continuously in unison to bring about that smooth ride that you all love.

The engine is the cooking pot and the epicenter of all that energy that rotates the wheels at those terrific speeds.

Now what really happens inside a car engine????. Before I answer that query we first of all need to know  the parts of the engine ,those parts that work unanimously together without failure, and if one fails then you end up seeing that friend we all call a mechanic


Parts of a car engine;
Ecu, Engine block, Top cover
Engine cylinder head, Cylinder head gasket, Ignition coils, Plugs, pistons, piston rings,
Crankshaft,camshafts, valves,valve seals, nozzle's, Camshafts, Valve's 
Nozzle's, Knock sensor, Oil gauge sensor, Water pump, Timing belt, Tensioner, Oil pump, Flywheel, Starter, Alternator, Dip stick, Intake manifold, Exhaust manifold,oil filter, air cleaner,oil pan

That list isn't exhaustive,them parts are many, but let's deal with this first

The ECU (electronic control module)
This is the computer that sends commands to various parts .its the command center of the car. This is the one that makes sure all parts are working as per stipulated, eg, if you step on the accelerator pedal,the computer sends a command to the fuel pump for fuel injection from the fuel tank,then commands the nozzle's to spray the fuel into the......


Fuel pump
Pumps fuel from the tank to the nozzle's

Nozzle's
This spray fuel into the intake manifold


Intake Valves
This opens up and injects the air fuel mixture into the cylinder head where it gets ignited by a spark plug


Ignition coils
They supply the spark plugs with the needed power to make sparks for fuel ignition,caution never touch their ends;
the sparkplug end, while the engine is running, you will get electrocuted


Spark plug
They fire the fuel inside the cylinder.
 They emit sparks that ignites/ fires up fuel. with no spark plugs no fuel will get ignited/burned so no energy

Intake manifold
This is where air comes in to be mixed with fuel before being injected into the valves


Camshafts
This controls the opening of valves

Crankshaft
This is where pistons are fixed and this is driven by pistons


Timing belt
Its the belt that keeps the camshafts in their correct position its driven by the crankshaft




Tensioner
Keeps the timing belt tight


Cylinder head
This houses the camshafts and all valves (intake and exhaust)



Engine block 
Houses pistons,crankshaft, there cylinders have been bored here

Top cover
Covers up the the top side of the cylinder head

Dip stick
Helps you to check the amount of oil in your engine



Water Pump Pumps water around the engine block and back to the radiator ,its one vital component of the engine cooling system, its driven by the fan belt

Oil pump
Pumps oil inside the engine to lubricate all the moving parts of the engine

Piston
Its the one that compresses fuel before its ignited by the sparks,its driven by fuel

Starter
Cranks the engine and gives it that breath of life,this gets its power from the battery, it  rotates the fly wheel which rotates the crankshaft,this then pushes the pistons up and they compress air fuel mixture ,the sparks are fired then boom ,the engine is alive

Fly wheel
This is the  ring wheel that's rotated by the starter when you ignite your engine,this part is fixed on one end of the crankshaft. This is a very important component because it also serves  as a counterweight to the engine ,this smoothens the engine idling run.

Alternator
Charges the battery and makes sure you have a steady power supply from the battery .


Exhaust manifold
Evacuates the engine ,all the unburned fuel and smoke from the burned fuel must be ejected out.

Oil pan/sump
Oil collects here before being pumped to parts of the engine,the oil pump sucks oil from this place,dirt and debris from the engine settles here too.


Now how do all this parts work out together for the car to run  smoothly?check out on the next  log
