    Abstract: Un mécanisme à poulie de tension (20) permet de maintenir la tension d'une courroie de transmission (18) dans un système à courroie de transmission, comprenant un bras (22) d'une poulie de tension, une poulie (24) montée sur le bras en rotation autour d'un axe de rotation (26), une plaque de montage réglable de manière pivotante (30), un moyen (28) de montage pivotant du bras sur la plaque de montage excentriquement par rapport à l'axe de pivotement de la plaque, et des moyens élastiques (54) associés effectivement au moyen de montage pivotant pour solliciter élastiquement la poulie (24) en engagement de tension avec la courroie de transmission (18). L'application d'un couple prédéterminé sur l'axe de pivotement de la plaque réglable donne à la courroie de transmission une tension sensiblement constante indépendamment de la longueur de la courroie, dans des tolérances prédéterminées.

    Abstract: A fuel injection rate shaping control system is provided which effectively controls the flow rate of fuel injected into the combustion chamber of an engine to improve combustion and reduce emissions by controlling the rate of pressure increase during injection. The injection rate shaping control system includes a rate shaping control device (10) including a rate shaping transfer passage (22) having a predetermined length and diameter specifically designed to create a desired injection pressure rate shape. In other embodiments of the present invention, two or more rate shaping transfer passages (72, 74) capable of producing distinct rate shapes are packaged in various fuel injection systems to selectively provide various rate shapes depending on operating conditions. Switching valves, i.e. solenoid operated three-way valves (76, 84, 86), may be used to direct the fuel or timing fluid flow to any one of the rate shaping transfer passages. Also, a dampening means in the form of a reverse flow restrictor valve (26) is positioned in the rate shaping transfer passage to dampen reflected pressure waves thereby minimizing the adverse effects thereof.

    Abstract: A fuel injector (10) includes a plunger assembly (20) disposed within a central axial bore (18) and including a lower plunger (22), an intermediate plunger (24), and an upper plunger (26). The lower plunger (22) reciprocates to meter a variable quantity of fuel and to inject this fuel. A timing chamber (34) formed between the upper and intermediate plungers (26, 24) receives an amount of timing fluid to create a variable length hydraulic link between the plungers (26, 24). The fluid is drained from the chamber (34) through a drain passage (38) at the end of the injection cycle. In a preferred embodiment, the drain passage (38) is located along the central axis of the intermediate plunger (24), and the upper plunger (26) is provided with a projecting portion (29) which moves into position as the timing chamber (34) collapses to effectively constrict the drain passage (38), thus changing the timing fluid flow function to a function which provides greater fluid pressure in the timing chamber (34), maintaining a large downward force on the lower plunger (22) preventing additional, undesired fuel flow into the combustion chamber.

    Abstract: Improved fatigue strength properties are achieved in an induction hardened microalloy steel useful for demanding service environments. The microalloy steel has low carbon and sulfur contents, comprising in % by weight, 0.15 % to 0.45 % C, 0.50 % to 1.60 % Mn, up to 0.20 % V, 0.001 % to 0.01 % S, balance Fe. The material is fabricated to a selected configuration, such as an engine crankshaft, for example. Selected surfaces of the fabricated article are hardened by induction heating. The article can be used directly after induction hardening or it may be tempered at low to moderate temperatures of from about 100 DEG C (200 DEG F) to 290 DEG C (550 DEG F) to achieve a desired surface hardness and compressive residual stress level. The controlled alloy chemistry and low tempering temperature provide a substantial increase in bending fatigue strength over conventional higher carbon grade steels.
