2. CYLINDER HEAD DEPARTMENT:
 This department’s main application is to fit the cylinder head of
engine.
 It even concentrates on proper dimensioning of inlet and exhaust
valves by grinding and polishing it by bare hands.
 After proper finishing and fitting of valves the cylinder head is

3. ENGINE WASHING AND ANTI- RUST DEPARTMENT:
 After dismantling all parts of engine it should be washed properly.
 It may consist of dust particles stuck in the corners.
 First the engine is washed with diesel and all dust particles are
removed with a scraper.
 After this process engine is washed with water and the water is
allowed to dry.
 And after the entire fitting of engine components is done the
engine is lubricated and anti-rust treatment is given to the engine.
 The following photograph show the process done by this
department:

4. CRANKSHAFT GRINDING DEPARTMENT:
 This department’s main purpose is to grind the crankshaft with
boring machine.
 Grinding of crankshaft is required due to improper dimensions, due
which it cannot properly fit into the crankcase.
 G.S.R.T.C has proper fixed dimensions in it manual for every part of
engine, according to which every parts are made efficient.
 Following photograph shows the working of this department:

5. ROTARY PUMP WORKING DEPARTMENT:
 This department assembles the rotary pump with its appropriate
parts and method.
 After completion of this process it is tested according to method.
 G.S.R.T.C. has a machine for testing of this pump.
 It shows the reading of accuracy of this pump.
 It even shows how much the pump pressurizes the diesel for
injecting diesel through injector.
 The reading is shown on a digital display.
 The following photographs show the machines and rotary pump:

9. PROJECT BY ARTHAR SILVESTER Page 9
6. INJECTOR TESTING DEPARTMENT:
 The fuel injectors of engine are sent to this department for their
testing.
 It contains an equipment for testing which has a reservoir in which
diesel is stored.
 After cleaning the injector it is placed on the injector holder.
 And as the pump is compressed, diesel reaches up to injector and it
is injected through holes in the injector.
 As the diesel sprays from injector’s holes the accuracy of that
injector is decided.
 Following photograph shows the work of this department:

10. PROJECT BY ARTHAR SILVESTER Page 10
7. ENGINE TESTING CENTRE:
 This department checks the proper working of engine after it is
completely ready to work.
 There about 8 to 10 machines in this department on which working
of engine is tested.
 Some connections are needed to be made on engine and when
power is supplied the engine runs.
 The following photograph indicates the workingofthisdepartment:

11. PROJECT BY ARTHAR SILVESTER Page 11
8. TYRE MOLDING DEPARTMENT:
 The old and worn out tyres whose grip/ pattern have been
damaged are remolded by this department.
 This department has large machines which contain a space for the
tyre to be fixed and remolded.
 A dye containing the pattern to be made on the tyre is placed in
the machine along with the tyre.
 After machine is closed with its cover and power is supplied to it, it
produces immense heat due to which the tyre is heated and the
pattern on the dye is formed on the tyre as it dissolves at high
temperature.
 The following photograph shows the working process of this
department:

12. PROJECT BY ARTHAR SILVESTER Page 12
9. BOILER ROOM:
 This is a room where boiler is kept.
 It consists of heating equipments and the heat produced is
supplied into the tyre molding department.
 The tyre molding department uses this heat to heathen up the tyre
for making its surface/ grip perfectly as per the decided pattern.
 Boiler even generates power for various departments which
require heating processes.
 The following photograph is of a boiler:
