Crankshaft damper and tone wheel assembly having noise reducing configuration

An internal combustion engine, comprising:

• a crankshaft connected to a plurality of piston rods and pistons, said crankshaft having a rotational axis;
• a crankshaft damper and tone wheel assembly connected to an end of the crankshaft, said crankshaft damper and tone wheel assembly comprising:
• a crankshaft damper having a same rotational axis as the crankshaft and including a hub portion and a ring-shaped portion connected to the hub portion by plural spokes, said ring-shaped portion having an inner circumference surrounding an area including the hub portion and the plural spokes;
• and
• an annular-shaped tone wheel connected to the crankshaft damper and having an inner diameter, an outer diameter, and plural teeth arranged at an equal pitch along the outer diameter, wherein,
• when viewed along a direction of the rotational axis, the annular-shaped tone wheel does not overlap a substantial amount of the area, and
• the annular-shaped tone wheel includes at least two openings extending through the annular-shaped tone wheel and positioned radially between the inner diameter and the plural teeth arranged along the outer diameter, the at least two openings being free from structure and sized and positioned to reduce noise radiation.
