    摘要： A housing in which a heat source for heating a member to be heated is disposable includes a first end and a second end in a longitudinal direction. Each of the first end and the second end is linked to a duct. A blowing unit is provided at the first end of the housing and causes an airflow in a space formed in a state in which the heat source is disposed in the housing. The duct linked to the second end of the housing is formed to extend from the second end. A length of the duct linked to the second end of the housing is longer than a hydraulic diameter by a predetermined number of times or more.

    摘要： A diagnostic equipment for an exhaust gas cleaning apparatus installed for an engine, comprising a misfire detector which detects the misfire of the engine, and a secondary-air-system failure detector which detects the failure of a secondary air system. An index corrector corrects a deterioration index calculated by a deterioration-index calculator, in accordance with the detected result of the detector. A deterioration decision unit decides if the diagnostic equipment has failed, by the use of the corrected deterioration index. In a case where the extent of the misfire or the like is severe, a decision interrupter interrupts the decision of the deterioration decision unit. Thus, even when the misfire of the engine or the failure of the secondary air system has occurred, the detection of the deterioration of a catalyst does not err. It is therefore avoided to erroneously replace the catalyst which has not deteriorated yet, or to run the engine in spite of the deterioration of the catalyst.

    摘要翻译： 一种用于发动机安装的废气净化装置的诊断装置，包括检测发动机失火的失火检测器和检测二次空气系统故障的二次空气系统故障检测器。 索引校正器根据检测器的检测结果来校正由劣化指数计算器计算出的劣化指数。 恶化判定单元通过使用校正后的劣化指数来决定诊断设备是否失败。 在失火等的程度严重的情况下，决策中断器中断劣化判定单元的判定。 因此，即使发动机失火或二次空气系统发生故障，催化剂劣化的检测也不会发生错误。 因此，尽管催化剂劣化，但是也可以避免错误地更换尚未劣化的催化剂或运行发动机。

    摘要： A diagnosing system for an engine diagnoses malfunctions that occur in a direct-injection engine in which fuel is injected into combustion chambers or a lean-burn engine. The present invention provides a diagnosing system for an engine capable of diagnosing malfunctions in an intake air flow intensifying component and a fuel supply component and of specifying a malfunctioning part without being affected by the difference between different engines, the difference in quality between parts and aging. The diagnosing system for an engine comprises: a selecting component for selecting either a first air-fuel mixture control component or a second air-fuel mixture control component according to operating condition of an engine; a combustion condition detecting component for detecting combustion condition of the engine; and decision component for deciding a malfunction on the basis of a first combustion condition detected by the combustion condition detecting component in a state where the first air-fuel mixture control component is selected by the selecting component, and a second combustion condition detected by the combustion condition detecting component in a state where the second air-fuel mixture control component is selected by the selecting component.

    摘要： A diagnosing system of a catalytic converter in an internal combustion engine has a detecting unit to detect an operating state of the engine and an air/fuel ratio control unit to adjust a fuel injection amount so as to keep an air/fuel ratio of a mixture that is inhaled into the engine to a target value. The operating state of the engine is detected, whereby it is confirmed that the engine lies in a predetermined operating region to execute a catalyst diagnosis on the basis of the detected operating state. In each of a plurality of different catalyst diagnosis regions, the performance of the catalytic converter or the performance of the catalytic converter array is diagnosed on the basis of the output signal of the first exhaust gas component sensor arranged on the upstream side of the catalytic converter array and the output signal of the second exhaust gas component sensor arranged on the downstream side.
