2-STROKE VS 4-STROKE ENGINES

You may have noticed I’m fond of cars and engines. That’s also why I’d like to be an engineer one day. Today I’m going to describe the most common types of car engines. You may have heard the terms 2 stroke and 4 stroke engines before, but do you really know all of the differences in their operation? I hope my post and the video below may help if you don't. 

The combustion engines are the most common type of engine with regard to means of transport like motorcycles, cars, busses and trucks but they are used also for small power tools like lawn mowers and chainsaws. In one of my articles in the blog I mentioned how they work but these two types have a small difference that change how they are made and used. How it works? A piston connected to the crankshaft by means of a connecting rod, flows up and down in a cylinder thanks to the force generated by the explosions of a mixture of air and gasoline. The connecting rod has the task of transforming the piston motion into a rotary motion.  But let’s talk about the differences about 2-stroke and 4-stroke engines.

To understand it we have to know  first the history of the Uyghurs .

The  Uyghurs  are a Turkic ethnic minority which lives mainly in Xingjian province of northwestern China.They are closer to the capital of Kyrgyzstan and Uzbekistan than to Beijing. They are also closer culturally to those Turkic groups than they are to the Han ( China's ethnic majority ) .

UCHRONIA

Now everyone who’s reading this post would be thinking: “What does Uchronia mean?

                Uchronia is a parallel course of history different from the original one only for a single event which takes a different course.

                This word comes from the Greek words  “ou” (no) and “kronos” (time).

                There are a lot of examples of these parallel universes: the most famous is the one in which Nazi Germany wins the second World War. The famous novel “The Man in the High Castle” imagines this specific Uchronia.

THE DAWN OF A NEW DAY

Every dawn brings a new day,

washing with the light of hope

the stains and dust of the spirit

empty of every past day.

You want to conceal yourself!

The heart does not obey,

diffused light from the eyes.

In life there is no hope

to avoid pain:

that you can find in the soul

the strength to bear it.
