Abstract: In a spark ignition type internal combustion engine that includes a variable compression ratio mechanism capable of changing the mechanical compression ratio, and a variable valve mechanism capable of changing valve characteristics of an intake valve or an exhaust valve, the variable valve mechanism is mechanically coupled to the variable compression ratio mechanism, and the variable valve mechanism is controlled in accordance with the compression ratio-changing operation amount of the variable compression ratio mechanism. The variable valve mechanism is coupled to the variable compression ratio mechanism without intervention of an electronic control unit. Therefore, the possibility of the interference between a piston and an intake valve resulting from an abnormality in a control system that includes an electronic control unit as an intervening unit can be eliminated.

Abstract: An adjustable camshaft sprocket assembly includes a hub and a sprocket body secured to the hub. A stud-receiving opening is defined in one of the hub flange and the sprocket body, and a tool-receiving opening is defined in the other of the hub flange and the sprocket body. The tool-receiving opening is aligned with the stud-receiving opening is adapted to receive a body portion of an adjustment tool, and the stud-receiving opening is adapted to receive an eccentric stud of the adjustment tool. Either the stud-receiving opening or the tool-receiving opening is elongated. Rotation of the adjustment tool when its body is located in the tool-receiving opening and its eccentric stud is located in the stud-receiving opening causes relative angular movement between the hub and the sprocket body. One or more fasteners are used to immovably secure the sprocket body to the hub after adjustment. A tool includes cylindrical base, a driving head, and an eccentric stud. The stud comprises a spring pin press-fit into a bore.

Abstract: A camshaft adjuster (1) for an internal combustion engine is provided, which includes a housing (21) and in which a relative angular position between a driving gear (22′) and an output element allocated to the camshaft is adjustable. In a first connection region (28), the housing is connected in a fixed manner to a support element (20) which is connected in a fixed fashion to a plastic toothed ring (19) in a radially outward direction in a second connection region (29). The outer surface of the carrier element (20) fits an inner surface of the toothed ring (19) in the second connection region (29). The carrier element (20) makes it possible to bridge the radial gap between the toothed ring (19) and the outer surface of the housing (21), and the second connection region accurately predefines a position of the toothed ring (19).

Abstract: A synchronous drive apparatus includes first and a second rotors. The rotors have multiple teeth for engaging engaging sections of an elongate drive structure. A rotary load assembly couples to the second rotor. The elongate drive structure engages about the rotors. The first rotor drives and the second rotor is driven by the elongate drive structure. One of the rotors has a non-circular profile having at least two protruding portions alternating with receding portions. The rotary load assembly presents a periodic fluctuating load torque when driven in rotation. The angular positions of the protruding and receding portions of the non-circular profile relative to the angular position of the second rotor, and the magnitude of the eccentricity of the non-circular profile, are such that the non-circular profile applies to the second rotor an opposing fluctuating corrective torque which reduces or cancels the fluctuating load torque of the rotary load assembly.
