    • A light emitting device, comprises a LED chip, and a case having an accommodating recession accommodating the LED chip, wherein the light emitting device emits light from an opening portion of the accommodating recession, the case is monolithically formed by injection molding of a resin composition preparing by mixing fine grains of specular reflection material and glass fibers as diffusion reflecting material as fillers therein, an inner surface of a side wall portion of the case works as a reflector that reflects the light emitted from the LED chip so that the light is output from the opening portion, and a thickness of the side wall portion is selected to be smaller than an average length of the glass fibers.

    • A catalyst degradation detection device, determines whether a three-way catalyst has degraded on the basis of the maximum value of the amount of oxygen stored by the catalyst. When determining whether the three-way catalyst has degraded, the amount of stored oxygen is calculated, and the responsiveness of change in the output signal of an oxygen sensor to oxygen concentration change in catalyst-downstream exhaust is measured. Then, on the basis of the responsiveness of the oxygen sensor which measured the oxygen storage amount, the oxygen storage amount is corrected by reducing the same such that the worsened the measured responsiveness relative to a reference value, the greater the reduction in the oxygen storage amount used in determining whether the three-way catalyst has degraded. The corrected oxygen storage amount used is prevented from deviating from the correct value on the basis of a worsening of the responsiveness of the oxygen sensor.
    • 催化剂劣化检测装置根据由催化剂储存的氧的量的最大值来判定三元催化剂是否劣化。 当确定三元催化剂是否劣化时,计算存储的氧气的量,并且测量氧传感器的输出信号对催化剂 - 下游排气中的氧浓度变化的响应性。 然后,基于测定氧气储存量的氧传感器的响应性,通过减少氧气存储量来减少氧气存储量,使得测量的响应性相对于参考值变差,氧储存量的减少越大 用于确定三元催化剂是否退化的量。 基于氧传感器的响应性的恶化,可以防止所使用的校正的氧气储存量偏离正确的值。
