Page 203 - CHAPTER IX INTERNAL COMBUSTION ENGINES Four-Cycle Engines with Explosive Charge 149. The Otto Cycle. Fig. 63 is an indicator diagram from a gas engine. Note that it represents FOUR successive strokes. At the point c, the piston is at the left-hand end of its stroke, the exhaust valve is closed and the inlet valve is open. The piston moves one full stroke to the right, drawing in a charge of P Atmospheric Pressure-

Page 14 - Boyle's Law. IF THE TEMPERATURE OF A GAS is KEPT CONSTANT, THE PRESSURE VARIES INVERSELY AS THE VOLUME.
Page 15 - FIG. 3. Charles' Law. (Constant Volume.) INCREMENTS OF TEMPERATURE. Fig. 3 illustrates this. At constant volume, the relation between pressure and temperature is represented by a straight line. The equation is, p = at + b, where a and b are constants. (6) IF THE PRESSURE OF A GAS IS KEPT CONSTANT, EQUAL INCREMENTS OF VOLUME ACCOMPANY EQUAL INCREMENTS OF TEMPERATURE. Again there is a straight line law: c = «wH- bi: Fig.
