(Teacher) “Well, the engine mechanism was studied, repaired and maintained until the
present by graduate students of our school, but in the future there is a possibility for
them to practice the job of Engine mechanic in other countries, when Romania might be
a part of the E.U. Therefore, it is useful to learn about the engine in an international
language, like English.
Right, that's all I have to say about the first part.
Moving on now to my next point, we will learn about the monocylindric engine , in
four stages, with spark ignition. Let’s take a look at the scheme on the blackboard,
please . Radu, what do you see there ?”
(Radu) “I see the cylinder, the piston, the crank of the tortuous shaft, the rod, the top
carcass, the collector of admission , the evacuation collector, the spark plug, the
superior bottom carcass, the inferior bottom carcass, the SA and the SE.”
