Hello world!
I AM Nikolas
Today we will talk about
engines and their
evolution in the past of
time

First engine in history
Industrial revolution
The first engine in history
was used steam for power.It
call the Watt steam engine
and use steam at a pressure
just above atmospheric to
drive the piston helped by a
partial vacuum. Improving on
the design of the 1712
Newcomen steam engine, the
Watt one, developed of the
steam engine.

The start of combustion engines
Automobiles
The lightweight petrol
combution engine, operating
on a four-stroke Otto cycle,
has been the most successful
for light automobiles, while
the more efficient diesel
engine it used for trucks and
buses.It first created by
Karl Bena, added to the
interest in light and
powerful engines.

The 70s fuel crisis
Combustion efficiency
The desing principles
favoured in Europe, beacause
of economic and other
restraints such as smaller
and twistier roads, leant
toward smaller cars and
corresponding to the desing
produced more economical
engines with earlier four-
cylinder desing rated at 40
horsepower compared with the
large volume v-8 american
one.

Electric motor
Electrification
After the bas side effects of
the compustion engine the
automotive word need a
change. The solution was to
go all electic with the first
succesful electic car been
the tesla model S. The model
S cover the same mile with a
friction of the cost of
similar petrol car some times
as 95% cheaper.

Electric motor
Electrification
An electric motor uses
elecrical energy to produce
mechanical energy, usually
through the interaction of
the magnetic fields and
current-carrying
conductors.Because the
reverse process can use as a
generator electic motors can
be often perform both task.

Hydrogen
Hydrogen is promising new
tehnology that some day maybe
we all run our cars with it.
Ofcorce first of all we must
solve the problems that come
with hydrogen and there are a
lot of them. At first it’s 8
time more expencive than the
current electic cars at the
market and it need energine
to save.
