    摘要： Grid structured data arranged for a spherical structured grid constituted by combining two component structured grids are visualized by using computer graphics technology. Coordinate conversion means 31 converts grid point coordinates of first and second component structured grids (referred to as N and E systems, respectively), represented by specific regions in spherical coordinates, into local xyz coordinates used in computer graphics. Filter means 32 obtains first and second graphic objects for the N and E systems, respectively. Using E system rotation and N and E system synthesis means 33, the second graphic object for the E system is rotated by 90 degrees with respect to an x axis of a first local xyz coordinate system, and is then rotated by 180 degrees with respect to a z axis of the first local xyz coordinate system, thereby obtaining the rotated second graphic object for the E system, and then, both of the graphic objects are synthesized.

    摘要： A direct injection ignition engine includes a piston with a cavity on a top surface thereof, an injector arranged at a peripheral portion of a combustion chamber to be faced to the combustion chamber for injecting a fuel directly into the combustion chamber, an ignition plug arranged to be projected to the combustion chamber for igniting the fuel introduced into the combustion chamber, an intake passage connected to the combustion chamber for introducing an intake air to the combustion chamber, intake air flow control valve arranged in the intake passage for controlling an intake air flow of an inclined vortex including a tumble component and swirl component produced in the combustion chamber, an actuator for driving the control valve, engine load detecting sensor for detecting an engine load, engine speed detecting sensor for detecting an engine speed, fuel supply controller, based on the output signals from the engine load detecting sensor and the engine speed detecting sensor, for producing control signals for the injector which include a fuel injection amount and fuel injection timing in a compression stroke for accomplishing a stratified combustion condition in which an air fuel mixture with an air fuel ratio greater than a theoretical one is concentrated around the ignition plug when an operating condition is in at least a low engine load and low engine speed condition, and, the fuel injection amount and fuel injection timing in an intake stroke for accomplishing a uniform combustion condition in which an air fuel mixture with an air fuel ratio greater than a theoretical one is uniformly and entirely dispersed in the combustion chamber when the operating condition is at least in a condition beyond said low engine load and engine speed condition with regard to the engine load and engine speed, and, producing control signals for the actuator to produce the inclined vortex of the air fuel mixture in the operating condition from the stratified combustion condition to the uniform combustion condition.
