The document provides details about the Uttar Pradesh State Road Transport Corporation (UPSRTC) and its operations, highlighting its history since 1947, the number of buses, and daily earnings. It also discusses the engine section focused on diesel engines, including descriptions of key components such as the cylinder block, piston, and turbocharger. The principles of diesel engine operation and its various parts are explained comprehensively.
UPSRTC Workshop,Lucknow
- 1. UTTAR PRADESH STATE ROAD TRANSPORT CORPORATION(UPSRTC),LUCKNOW BY-SUDHIR YADAV 1212240219 SRMCEM TOPIC-ENGINE SECTION
- 2. INTRODUCTION • Passenger road transport services in U.P. started on 15th May, 1947 • First route is from LUCKNOW – BARABANKI • There are around 7668 buses are running • Operate over 2.5 million kilometers • Over 1.3 million peoples travelling everyday • Earning of UPSRTC over Rs.38.3 million everyday
- 3. OBJECTIVES • Heavy maintenance and repair of vehicles • Reconditioning of major assemblies • Renovation of buses • Construction of bodies on new chassis • Tyre retreading
- 4. WORKSHOP • Central workshops in Kanpur 1. Central Workshop, Rawatpur 2. Dr. Ram Manohar Lohia Workshop, Allen Forest • Car Section is established in Lucknow.
- 6. ENGINE SECTION • Study about diesel engine • Components of diesel engine • Working of diesel engine
- 7. DIESEL ENGINE • The engine was developed by German inventor Rudolf Diesel in 1893. • The engine works on the principle of diesel cycle • A diesel engine is an internal combustion engine. • It uses the heat of compression to initiate ignition to burn the fuel that has been injected into the combustion chamber.
- 8. SOME COMPONENTS OF DIESEL ENGINE • Cylinder Block • Gasket • Manifold: inlet and outlet • Turbocharger • Flywheel • Piston • Piston Rings • Connecting Rod • Crankshaft • Camshaft • Fuel injector • Valves
- 9. CYLINDER BLOCK • It is the basic structure of an engine. • Normally made of ALUMINUM ALLOYS or CAST IRON. • Provides Strength with relatively simple design. • Supports and aligns internal parts.
- 10. GASKETS • It serve as a sealant between engine block and head where they bolted together.
- 11. INLET MANIFOLD • Piping system which delivers incoming air to the cylinder. • They made up of cast metal, plastic or composite materials. • In SI engine fuel added to the air in intake manifold
- 12. OUTLET MANIFOLD • Piping system which carry exhaust gases away from the system. • Made up of CAST IRON.
- 13. TURBO CHARGER • Turbine compressor used to compress incoming air into the engine. • The turbine is powered by the exhaust flow of the engine so it take very little useful work from engine.
- 14. FLYWHEEL • To store the energy , provide energy when it is needed and store. • firmly bolted to the hub of the crankshaft
- 15. PISTON • A cylindrical-shaped mass that reciprocate back and forth in the cylinder transmitting force to the crankshaft. • The top of the piston is called CROWN and the sides are called SKIRT. • PISTON is made up of cast iron, steel or aluminum.
- 16. PISTON RINGS • Metal ring that fixed into a circumferential grooves around the piston. • Made up of highly polished chromed steel • It make a seal between piston and cylinder walls. • It also used for lubrication purpose.
- 17. CONNECTING ROD • Rod connecting the piston with rotating crankshaft. • Provided the contact from piston to the crankshaft. • Usually made of STEEL or ALLOY FORGED but in small engine it can be made of ALUMINUM.
- 18. CRANKSHAFT • Rotating shaft through which engine’s work output supply to the system. • Mostly they made of forged steel or cast iron. • It is attached with the engine block by MAIN BEARING. • Having crank weights attached with crankshaft
- 19. CAMSHAFT • Rotating shaft used to push the valves at proper timing in engine cycle. • Can be control Hydraulically or Mechanically. • Modern engine have more than two cams
- 20. FUEL INJECTOR • A pressurized nozzle which spray the fuel into the incoming air on SI engine. • Injector directly spray at the combustion chamber. • It is placed at the Centre of the combustion chamber.
- 21. VALVES • Used to allow the flow into and out of the cylinder at proper time in the cycle . • VALVES are made of forged steel. • Two stroke engine do not have valves they have ports system (slot).
