Abstract: PROBLEM TO BE SOLVED: To provide an improved bias spring arbor for reducing stress and hysteresis of a spring.
SOLUTION: A torque bias coil spring for a camshaft phaser is disposed in an annular well formed in a phaser rotor and has a central arbor for supporting the spring. The radius of the central arbor is set so that the spring has a radial operating clearance of 5-10% in the prior art. However, the improved arbor includes regions of higher radius at the arbor ends supporting the innermost and outermost coils of the spring. These regions serve to prevent the spring from being laterally displaced during torsional motion, thus minimizing the relative motion at the spring contact points, reducing stress on the spring, and improving the efficiency of the spring by reducing frictional hysteresis.

Abstract: PROBLEM TO BE SOLVED: To provide a control device for confirming failure in a fuel injection system. SOLUTION: An engine system is equipped with a first injection device and at least one other injection device. These injection devices are each equipped with a needle control valve and a pressure control valve. The control device is equipped with an input part for receiving data regarding a parameter of the engine system, and an output part for outputting a command for controlling each valve of the injection devices. A processing device is constituted to output a command for maintaining the needle control valve of the first injection device in a closed state and monitor the parameter of the first engine system so that injection of the first injection device is not performed. The change in the parameter of the first engine system indicates that the first injection device is operating substantially normally within the parameter operation, and no change or substantially no change of the parameter of the first engine system indicates that there is a failure in the first injection device.
