ENGINE SECTION
• Study about diesel engine• Components of diesel engine•Working of diesel engine
![Page 7: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/7.jpg)
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.
![Page 8: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/8.jpg)
SOME COMPONENTS OF DIESEL ENGINE
• Cylinder Block• Gasket•Manifold: inlet and outlet• Turbocharger• Flywheel• Piston• Piston Rings
• Connecting Rod• Crankshaft• Camshaft• Fuel injector• Valves
![Page 9: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/9.jpg)
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.
![Page 10: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/10.jpg)
GASKETS
• It serve as a sealant between engine block and head where they bolted together.
![Page 11: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/11.jpg)
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
![Page 12: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/12.jpg)
OUTLET MANIFOLD
• Piping system which carry exhaust gases away from the system.•Made up of CAST IRON.
![Page 13: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/13.jpg)
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.
![Page 14: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/14.jpg)
FLYWHEEL
• To store the energy , provide energy when it is needed and store.• firmly bolted to the hub of
the crankshaft
![Page 15: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/15.jpg)
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.
![Page 16: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/16.jpg)
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.
![Page 17: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/17.jpg)
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.
![Page 18: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/18.jpg)
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
![Page 19: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/19.jpg)
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
![Page 20: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/20.jpg)
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.
![Page 21: UPSRTC Workshop,Lucknow](https://reader034.fdocuments.in/reader034/viewer/2022042604/5876d8281a28ab1d238b62f9/html5/thumbnails/21.jpg)
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).
