1.	Which of the mentioned below is the Held and favary for the thickness of the piston head?(a) th=0.032D+1.5(b) th=0.032D+1.5d(c) th=0.032D+1.5h(d) th=0.032V+1.5DThe question was asked in homework.I'm obligated to ask this question of IC Engine in division Design of IC Engine Components of Automotive Engine Design
Answer» The CORRECT answer is (a) th=0.032D+1.5 To explain I would SAY: Held and Favary suggested an empirical formula for finding the THICKNESS of the piston head and it is given by th=0.032D+1.5, where D is bore DIAMETER.
