when the crank is on its dead points. In order, therefore,that the entrance port may be a little open when the pistonarrives at the end of its stroke (Fig. 735, II.), the angleA C B^ must exceed 90° by an angle A C O =■ a z= H^C B^.This angle is called the angular advance of the eccentric.The… … eccentricity. The angle of advance then is the angle madeby the eccentricity with the vertical to the direction of thevalve face, when the crank is at one of its dead points. § 461.—Double Eccentric witli Link.—In order tochange the travel of the valve, and thus obtain a greateror less time for…
