Components of ic engine
- 1. COMPONENTS OF IC ENGINE Prince Singh
- 3. ENGINE BLOCK # Body of an engine containing the cylinders. # Normally made of ALUMINUM or CAST IRON. # Old engine also have a case for water jackets.
- 4. CAMSHAFT # Rotating shaft used to push open valves at proper timing in engine cycle. # Can be control HYDRAULICALLY or MECHANICALLY. # Modern engine have more then two cams.
- 5. CRANKSHAFT # Mostly they made of forged steel or cast iron. # It is attached with the engine block by MAIN BEARING. # Rotates in circular motion # Having crank weights attached with crankshaft # It through which engine is work output supply to the system. # It rotate by which work
- 6. 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.
- 7. 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. # Aluminum piston are light . Used for light engine . # Piston is one of the important component of engine.
- 8. PISTON RING # 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.
- 9. 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).
- 10. VALVE SPRING # The spring which attached at the valve. # Push back the valve / closed the valve.
- 11. CYLINDER OR COMBUSTION CHAMBER # The end of the cylinder between head and piston face where combustion take place.
- 12. CRANKCASE # The part of the engine block surrounding the rotating shaft. # The oil pan makes up part of the crank case housing.
- 13. CARBURETOR # CARBURETOR is used for making a air and fuel mixture . # It is replaced by EFI system. # A proper mixture is needed for proper combustion so that carburetor used. # It mixing up the fuel and air . # Making a rich or lean mixture as requirement.
- 14. RADIATOR # It is an HEAT EXCHANGER. # It is usually mounted in front of the engine in the flow of the air. # Used to cool down the engine and run proper thermodynamic cycle.
- 15. SPARK PLUG # Electric device used to initiate combustion in SI engine. # Made up of the metal surrounded by the ceramic insulation. # Spark plugs only used in SI engine
- 16. INTAKE MANIFOLD # Piping system which delivers incoming air to the cylinder. # They made up of cast metal ,plastic or composite materials. # In IS engine fuel added to the air in intake manifold.
- 17. EXHAUST MANIFOLD # Piping system which carry exhaust gases away from the system. # Made up of CAST IRON.
- 18. FLYWHEEL # To store the energy , provide energy when it is needed and store. # It keeps the engine rotating.
- 19. 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.
- 20. OIL PAN # Oil reservoir usually bolted at the bottom of the crankcase. # Act as a oil sump.
- 21. OIL PUMP # Pump used to distribute oil from oil pan to the required point for lubrication purpose.
- 22. OIL FILTER # To filter the oil. # Clean oil is need for proper lubrication.
- 23. STARTER Starter is an electrical device which is used to provide initial torque to the engine at the time of start.
- 24. 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.
