Abstract:
1. An engine comprising: a crankshaft connected to at least one piston by a connecting rod, the crankshaft configured to rotate about a crankshaft axis; the crankshaft including a first axial portion that lies on the crankshaft axis and is substantially symmetric about the crankshaft axis; the crankshaft including a crankshaft journal having a first journal side wall connected to a second journal side wall by a crankpin member radially offset from the crankshaft axis; the first journal side wall disposed axially between the first axial portion and the crankpin member and extending radially away from the crankshaft axis and beyond the first axial portion so as to define an axial facing surface facing in a direction substantially parallel to the crankshaft axis and toward the first axial portion; a timing plate having a central hole and a plurality of indicia on a periphery portion of the timing plate; the timing plate including at least one protruding portion extending in the direction substantially parallel to the crankshaft axis and toward the axial facing surface of the first journal side wall; wherein the timing plate defines a first hole through the timing plate in a direction substantially parallel to the crankshaft axis; wherein the timing plate defines a second hole through the timing plate in a direction substantially parallel to the crankshaft axis; wherein the first hole and the second hole are adjacent to each other so as to define the at least one protruding portion as an elongated member between the first hole and the second hole; wherein the first hole extends radially to define a first radial side of the elongated member; wherein the second hole extends radially to define a second radial side of the elongated member; wherein a radial length of the first and second radial sides of the elongated member is greater than a distance between the first and second radial sides in an angular direction; wherein the elongated member is bent so as to protrude from a first axial facing surface of the timing plate; wherein the first axial portion of the crankshaft extends through the central hole of the timing plate; wherein the axial facing surface of the first journal side wall of the crankshaft defines at least one receiving portion configured to receive the at least one protruding portion; and wherein the timing plate is configured to move along the crankshaft axis.
