摘要： PROBLEM TO BE SOLVED: To provide a hydrogen storage alloy which has a large hydrogen storage content, and has high hydrogen storing/discharging rates.
SOLUTION: In the hydrogen storage alloy consisting of two or more phases, at least one phase is a stable hydride formation phase comprising one or more kinds of stable hydride formation elements reacted with hydrogen so as to form stable hydride. As for the stable hydride formation phase, in the observed cross-sectional structure, the diameter of minor axis is ≤5 μm and the phase is dispersed at the intervals of ≤1 μm, and the phase is further separated since the one or more stable hydride formation elements form hydride. There are many crystal grain boundaries since the stable hydride formation phase is separated. Thus, the diffusion paths of hydrogen increase, and the diffusion rate of hydrogen is made high.

摘要： PROBLEM TO BE SOLVED: To previously predict operation stability after adjusting ignition timing when adjusting ignition timing in an ignition timing control device for an internal combustion engine. SOLUTION: Supposed ignition timing SAi advanced more than the present ignition timing SAc is assumed (step 118). Cylinder pressure history data under the supposed ignition timing SAi are created by a significant number of cycles (step 120). Based on the cylinder pressure history data, knocking cycle frequencies under the supposed ignition timing SAi are predicted (step 134). Based on the predicted knocking cycle frequencies, ignition timing is set to approximate MBT (minimum advance for best torque) within a range not causing knocking (steps 150-158).

摘要： PROBLEM TO BE SOLVED: To aim at quick convergence of an engine control parameter to the vicinity of a stability limit, regarding a control device for operating an internal combustion engine at the vicinity of a stability limit. SOLUTION: Indicated torque ITQ is computed by integrating the combustion pressure of the internal combustion engine over 720° CA. At each operation condition of the internal combustion engine and with a change of an ignition timing, correlation materialized between the indicated torque ITQ and standard deviation σ of the ITQ is stored (Relation of a solid line relation and relation of a broken line). Measured indicated torque ITQ is applied on correlation and the standard deviation σ of the ITQ is estimated. The delay limit of an ignition timing is controlled such that the standard deviation σ does not exceed a decision value σthr. COPYRIGHT: (C)2006,JPO&NCIPI
