A spread illuminating apparatus includes LEDs as point light sources fixedly mounted on a flexible printed circuit, a light conductor plate having a light inlet surface, a light reflector plate disposed under the light conductor plate, a light absorbing member constituted by a black tape, and a sheet metal case having walls on all four sides and housing the component members described above. The fuel injector produces an asymmetrical injection volume, so that the electrodes of the spark plug are not directly affected by liquid fuel. The plurality of script modules may be associated with a script. The portion of code includes the point variable. Such topologies include, but are not limited to, PWM regulators and hysteretic regulators.
