Abstract

new request update engine and vehicle The compression mechanism is placed between the two ends of the camshaft in the Axial direction of the camshaft The pressure relief mechanism includes a counterweight and compression release cam The counterweight is supported in a rotatable manner on the camshafts. The compression cams alternate between the mechanical contact conditions. Valves with no contact with the valve mechanism in response to the rotation of the counterweight. The counterweight includes the inner ring contact. side ring contact part The inner ring is aligned with the inner ring of the bearing in the axial direction of the camshaft The inner ring contact is within the radial direction of the surface. The inner edge of the outer ring of the non-slip
