DESIGN OF PISTONS
Prepaded by :Mehul Gohel (110503119010)Chirag Patel (110503119006)
1
PISTON DESIGN CONSIDERATIONS
Pistons must:Contain cylinder pressureTransmit the pressure created by combustion to force
on the connecting rodProvide a place for oil control and compression rings
to be located
2
PISTON DESIGN CONSIDERATIONS
Pistons must:Be rigid enough to not deform under the tremendous
pressures and forces encounteredBe ductile enough to absorb pressure peaks and not
shatterRetain the proper shape under the extreme
temperatures encountered

PISTON CONSTRUCTION
MaterialsCast iron (used in very old engines)Cast aluminum (most common)Forged aluminumHypereutectic alloys (high silicon content aluminum)Carbon Graphite (being tested)

PISTON PIN
Piston Pin OffsetThe piston pin is offset towards the major thrust side
of the piston to reduce piston wear, and piston noiseThe major thrust side is the side that is loaded during
the power eventThe minor thrust side is the side loaded during the
compression event
