Why Are Cars Called ‘Cars’? — Learn Even More About Cars
Why is a car called ‘car’? Learn how the term, ‘car’ came into existence. Why not know more about cars in general?
The word 'Car' originates from the Latin word 'Carrus or Carrum', which means 'wheeled vehicle'. In the Middle English context, the Old North French term, 'Carre' implies a two-wheeled cart. Meanwhile in the ancient language, Gaulish, the term 'Karros' implied a self-propelled automobile.
Historians believe that 'car' appeared in the English vocabulary around the 1300s. They claim that there was also a term called 'Craet' in Olden English, denoting some means of transport. 'Craet' eventually transformed into 'Cart'.
Now that you know how the term came into existence, let us learn more about how the actual car came into existence.
Although there were many forms of automobiles from an early period, the first modern car came into existence in 1886. German Inventor, Karl Benz was the mind behind it, and he named it the Benz Patent-Motorwagen.
But, that wasn't a mass produced model and was inaccessible to the masses. It was Henry Ford (The man behind Ford Motor Company), who built the affordable 'Model T' in 1908. From then, cars became more common.
But, how does a car work? Well, you don't have to be a rocket scientist to learn this. Let's learn how a normal internal combustion engine works.
Let us start off with the basic layout. A basic Internal Combustion Engine or ICE works when fuel-air mixture ignites in a 'Cylinder', forcing a 'Piston' to move away. This motion rotates the 'Crankshaft', connected to a metal disc called 'Flywheel'. This is where the 'Clutch' comes to play.
Once the engine starts, it keeps on running. But, the wheels shouldn't always rotate with it, right? A clutch basically prevents this.
The clutch lies between the Flywheel and the Transmission (Gearbox). It engages and disengages them, with the help of a clutch pedal.When the Clutch pedal is pressed, the contact between the Flywheel and the Transmission cuts, and only the engine runs. When it isn't pressed, the motion of the rotating Flywheel transfers to the Transmission, and ultimately reaches the wheels.But what about the difference between a Petrol and a Diesel engine?
A Petrol engine uses a Spark Plug to initiate combustion in an engine. A Diesel engine uses a Fuel Injector to spray fuel into the cylinder, while the air is being compressed. Compressed air plus fuel causes a flame.
The process seems confusing? Well, let us talk about the steps, or more precisely, the strokes involved.
Intake
-
Intake
valve
opens;
Piston
moves
down;
Air
comes
in;
Compression
-
Intake
valve
closes;
Piston
moves
up;
Air
is
compressed
Power
-
Fuel
is
sprayed
by
a
Fuel
Injector(Diesel
Engine);
Or
Spark
Plug(Petrol
Engine)
gives
a
spark;
In
both
cases,
the
air-fuel
mixtures
ignite,
and
the
force
created
moves
the
Piston
down.
Exhaust
-
Exhaust
valve
opens;
Piston
moves
up;
Burnt
gases
leave
the
cylinder.
There
are
four
strokes
above.
Hence,
a
4-stroke
engine!
(In
2-stroke
engines,
things
are
different
-
No
valves;
Intake+Compression
is
one
stroke,
and
Power+Exhaust
is
another
stroke)
Let us talk a bit more. Do you know the types of engines?
Engines are generally classified by the arrangement of cylinders as shown in the image.
So, to recap how an ICE vehicle moves, the motion transfers from -Engine(Crank)-Flywheel-Clutch-Transmission-Propeller Shaft-Differential(Rear Wheel Drive)/Transaxle(Front Wheel Drive)-Wheels
There you have it. Some basics facts to know about a car's working. Wasn't that hard, right?
DriveSpark Thinks!
An Automobile is made up of several components and involves many laws of Physics. Explaining everything on a single go is close to impossible. But it is always good to know a thing or two more about the things we like, right? That said, watch out this space for more car-related facts and trivia.
