= 19 d = 19 14 = 71.1 mm
and maximum pitch of the studs
= 28.5 d = 28.5 14 = 106.6 mm
Since the pitch of the studs obtained above (i.e. 82.2 mm) lies within 71.1 mm and 106.6 mm,
therefore, size of the stud (d ) calculated above is satisfactory.
d = 14 mm Ans. 32.5 Piston
The piston is a disc which reciprocates within a cylinder. It is either moved by the fluid or it
moves the fluid which enters the cylinder. The main function of the piston of an internal combustion
engine is to receive the impulse from the expanding gas and to transmit the energy to the crankshaft
through the connecting rod. The piston must also disperse a large amount of heat from the combustion
chamber to the cylinder walls. Fig. 32.3. Piston for I.C. engines (Trunk type). Internal Combustion Engine Parts n 1133 The piston of internal combustion engines are usually of trunk type as shown in Fig. 32.3. Such
pistons are open at one end and consists of the following parts :
1. Head or crown. The piston head or crown...
