The motor to two times in its mechanical essence is how much more simple
can imagine.
A piston flows in a cylinder bound from a connecting rod to the tree
motor. During his motion it completes alternatively and contemporarily
two different operations.
In his run toward the heading the piston compresses the mixture and
it prepares it for the lighting, at the same time it creates a depression
in the carter that so it inhales fresh mixture through the carburetor.
Happened the lighting, in its run toward the lower part the piston transforms,
through the connecting rod and the tree to elbows, the pressure on the
surface in usable job.
It discovers the light of unloading then, through which the gases go
out in the atmosphere, at the same time it compresses the contained mixture
in the carter that, following the decants, it discharges in the cylinder
where it effects the job of washing making also go out the last residues
of gas of unloading. Subsequently the piston goes up again, the lights
are closed and the cycle restarts, since this series of operations occupies
a phase of slope and one of descent only, the motor has been note called
to two times.
Says so, it seems everything extremely easy, but not as soon as him
search that something in more, they begin the troubles; is necessary to
consider, in fact, that small it is the number of the involved parts and
the phases and more the phenomenons are complex that are verified interior
shot the motor, and besides that they exist between the phases and the
phenomenons that accompany them complex and important correlations.
Every more small particular of this series of operations has a direct
correlation on all the others, for which doesn't think to operate only
on a part and leaving to be the rest, has always a general vision of the
whole, otherwise the only result they will be alone problems.
I close remembering that whatever change that interest the motor, or
also only the loom, fit to increase or decreasing the power of the same
forces the driver to a new registration or to conduct the motorbike only
on private areas.
