Abstract: PURPOSE: Structure of a piston head for an engine of directly injecting gasoline is provided to improve the efficiency of fuel through collecting the fuel near a spark plug. CONSTITUTION: Fuel injection is started before a top dead center for 340. Herein, a recess unit at a lower portion of an injector(16) side from a bowl unit(24) is formed in an identified angle with an angle of the injector. Therefore, the fuel injected from the injector is flowed to a tangent direction of the bowl unit. Angle of a portion opposite from the suction port of a cylinder head(28) is formed to flow air through the suction port(18) toward inner direction. A squish unit(26) lowered from an outer portion of the bowl unit toward the piston head is formed to prevent tumble fluctuation from being changed into eddy current according to formation of the bowl unit. By increasing area of the squish unit, sucked amount of air is increased while increasing eddy current at a post period of combustion. Therefore, the fuel is completely burned.
Abstract translation: 目的：提供用于直接喷射汽油的发动机的活塞头的结构，以通过收集火花塞附近的燃料来提高燃料的效率。 构成：在上止点340之前开始喷射燃料。这里，以与喷射器的角度成一个确定的角度形成一个来自碗形单元（24）的喷射器（16）侧下部的凹部单元。 因此，从喷射器喷射的燃料流入碗单元的切线方向。 形成与气缸盖（28）的吸入口相对的部分的角度使空气通过吸入口（18）向内侧流动。 形成从碗状单元的外侧朝向活塞头下降的挤压单元（26），以根据碗单元的形成来防止滚筒波动变成涡流。 通过增加挤压单元的面积，在燃烧后期增加涡流的吸入量增加。 因此，燃料完全燃烧。

Abstract: A novel and improved method and apparatus for generating a reduced peak amplitude high data rate channel comprised of a set of lower rate channels is described. The set of lower rate channels (90, 92) are phase rotated before being summed and transmitted. The amount of phase rotation is dependent on the number of channels used to form the higher rate channel (102). In an embodiment wheretwo lower rate channels (90, 92) are used, the in-phase and quadrature-phase components of the two channels are complex multiplied (94, 96) before upconversion with an in-phase and quadrature-phase sinusoids. For a high rate channel comprised of more than two lower rate channels, the in-phase and quadrature-phase component of each channel is upconverted with a set of sinusoids that are phase offset from one another.

Abstract: PURPOSE: A device and a method for reducing exhaust gas by using an NOx sensor are provided to improve air-fuel ratio by simple circuit. CONSTITUTION: An exhaust manifold close coupled catalytic converter is connected to an engine, and is welded to an exhaust manifold. An NOx occlusion type catalytic converter temporarily holds NOx in lean-burn driving, and restores NOx in theoretical air-fuel ratio driving. An NOx sensor is installed at the rear end of the NOx occlusion type catalytic converter, senses the concentration of NOx, and determines the regeneration and desulfurization timing of the NOx occlusion type catalytic converter.
