Bhawesh Prajapati completed an industrial training internship from June 13 to July 15, 2019 at the Uttarakhand Transport Corporation Workshop in Dehradun. The workshop maintains over 1,200 buses for the state-run transportation corporation. During the internship, Prajapati learned about and assisted with maintenance in various departments including the engine, brakes, gearbox, and axle sections. The practical experience and exposure to the industrial work environment improved Prajapati's confidence and provided valuable hands-on learning about vehicle maintenance processes.

7. Work Stations (Department of Training/area)
• Front Axel Section
• Rear Axel Section
• Brakes Assembly Section
• Leaf Spring Section
• Alternator & Self-Starter, Electric Section
• Gear Box Section
• F.I.P. Section
• Engine Section
• Steering Section
• Clutch Assembly Section

8. This section fabricates and maintain Suspension.
Because of the up’s and down’s the vehicle get’s so
many shock’s, to prevent those shock the LEAF
SPRINGS are used. They are Semi-Elliptical in shape.
▪ The total number of the Leaf Spring Suspension in a Bus is 4.
▪ Each contains 15 leaf Springs.
▪ In Front axle the length of Spring is 74 inches and decreases
4 inches in each to downwards.
▪ In Rear Axle the length of Spring is 78 Inches and simultan -
eously decreases as in front axle.

9. Alternator, Self-Starter Motor Section
ALTERNATOR is used to charge the battery it generates 3-phase AC current
• Voltage generation=14.2—14.8v.
• Ideal output during slow running is14.2v.
• At 2000rpm is 14.8v.
Its parts
• Rotor-it is a magnet.
• Stator-it generates AC.
• Rectifier plate-it converts AC to DC.
• REGULATOR -it controls the o/p voltage.
SELF-STARTER MOTOR is used to crank the engine to make
it runs on its own power.

10. F.I.P. Section
Almost in every I.C. Engines Fuel Injection Pumps are used for delivering the fuel
in desired pressure, amount, time to the cylinders.
The Fuel suck by Fuel Pump from the tank at a low pressure with the help of a low
pressure pump via filter and than after reaching a certain pressure it is delivered
to the high pressure pump and distributer then using cam it sends the high
pressure fuel to the desired fuel injector with the help of it’s rail and due to the
varying rpm of engine and pumping capacity. The extra fuel is returns to the fuel
tank via pressure relief valve. It also consist of Mechanical Governor which helps
in the controlling of fuel supply under varying load conditions.
• Injection Pressure is different for different engine.
• CAM Sequence- 1-5-3-6-2-4.
• Direction of Rotation- Clock Wise.

16. Project assigned during training,
We had done the overall maintenance work during our training period.
Outcomes of training,
❑ Practical Experience
❑ Confidence Boost
In our industrial training, we were introduced to industrial environment.
We learned discipline and cooperation during training & we felt good
when we came in contact with engineers & workers. Most importantly
we had learnt the process of performing work in workshop with complete
knowledge of Departments which will be useful for us when ever we
go at industries or workshop as an Employee.
