Abstract:
As is well-known, automobiles today
play a vital role in traffic and transport
in the cities as well as in out-of-the-way
places throughout the world. It is said
that the number of cars constitutes a
barometer of the culture and economy
of the area containing them.
In order to maintain the high performance
of cars, it is necessary to overhaul
them periodically, and repair them
completely in the event of trouble.
