  1. 1. Manufacturing process for analuminum alloy piston<br />Group 5<br />Eugene Oo<br />
  2. 2. What is a piston?<br />Component of engines, reciprocating pumps, gas compressors and pneumatic cylinders.<br />Moving component contained by a cylinder and is made gas-tight by piston rings. <br />In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.<br />In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder<br />
  3. 3. Components of a typical, four stroke cycle, DOHC piston engine. (E) Exhaust camshaft, (I) Intake camshaft, (S) Spark plug, (V) Valves, (P) Piston, (R)Connecting rod, (C) Crankshaft, (W) Water jacket for coolant flow.<br />http://www.animatedpiston.com/BMW.htm<br />
