摘要： A computer simulates a relationship between a fuel-rate of fuel which collides with the cavity of the piston and the fuel injection timing, and/or the relationship between the fuel-rate of fuel which collide with the cylinder inner wall and the fuel injection timing. A range of the fuel injection timing in which the combustion state is stable is computed based on the simulation results. This range of fuel injection timing may be defined as the measuring range in which the measure points are arranged. Furthermore, the fuel injection timing is varied gradually around an upper and lower limit values of the measuring range and the engine torque is measured. The measuring range is corrected so that the combustion state becomes stable.

摘要： Anisotropically shaped ceramic particles are represented by the general formula {(K1-x-yNaxLiy)4(Nb1-zTaz)6O17+aMeOb} (where Me is at least one element selected from the group consisting of antimony, copper, manganese, vanadium, silicon, titanium, and tungsten; and b is a positive number determined by the valence of Me), where x, y, z, and a satisfy 0≦x≦0.5, 0≦y≦0.3, 0≦z≦0.3, and 0.001≦a≦0.1, respectively. The anisotropically shaped ceramic particles have a plate-like shape. The average particle size is 1 to 100 μm, and the ratio D/t of the maximum diameter D of a main surface to the thickness t in a direction perpendicular to the main surface is 2 or more, preferably 5 or more. Thus, anisotropically shaped ceramic particles suitable as a reactive template for preparing a crystal-oriented alkali metal niobate-based ceramic can be produced at relatively low production costs without the need for a complicated production process.

摘要： A piezoelectric ceramic whose resonance frequency temperature characteristic can be easily adjusted is provided. It contains first and second parts (11 and 12) which can be alternately stacked layers. The first and second parts (11 and 12) are each composed of a compound having a bismuth layer structure, such as a complex oxide containing at least Sr, Bi, and Nb, and have degrees of c-axis orientation different from each other. Since the resonance frequency temperature characteristics change according to the degree of orientation, the first and second parts (11 and 12) having different degrees of orientation are appropriately combined so that the resonance frequency temperature characteristics of the piezoelectric ceramic (2) as a whole is easily adjusted.
