13. Crank Case
 It is made of cast iron.
 Other parts of the
engine are directly or
indirectly attached to
it.
 It is equipped with
holes, by which the
engine may be firmly
anchored to its
foundation.

15. Piston & Connecting Rod
 Piston of an engine
move back and forth in
the cylinder owing to the
explosion of the fuel

 Piston is surrounded by
piston rings which
prevent the friction
losses.
 Connecting rod
connects the piston and
crank shaft

17. Engine Testing
 After assembly, engine is brought to engine testing section.
 In this section practical checking of engine is done on engine and water
supply is connected to it, then the engine is started with the external DC
supply.
 After this, the proper operating of valves is done, the engine is kept running
for two hrs.
 During running the load is also varied and various properties like lubricating
oil pressure, load capacity, fuel consumption etc is checked.
