Abstract: In a method for identifying the state of an NOx storage catalyst which is cyclically loaded with NOx in the exhaust stream of an internal combustion engine and regenerated, two electrical defining quantities, independent of each other, of the electrically complex impedance of the NOx storage catalyst are detected, one of the two electrical quantities being a measure of the degree of loading of the NOx storage catalyst, and from the second electrical quantity the point in time being identifiable for the end of the regeneration process of the NOx storage catalyst.

Abstract: 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.

A stagnation region is provided within the particle trap such that all the exhaust gas passed through the exhaust gas particle trap is directed toward the stagnation region therein and at least a portion of debris carried with the exhaust gas is retained within the particle collection chamber.

Abstract: A catalyst is warmed up by a rapid heating control that retards ignition timing and increases an intake air amount. Then the warm up is completed or a transmission is shifted to a drive range, the ignition timing is gradually advanced and the intake air amount is gradually decreased. Therefore, an engine speed is smoothly changed from the rapid heating control to the normal control without a torque shock. Additionally, a beginning of the advancing of the ignition timing is delayed by a predetermined delay time relative to a beginning of the decreasing of the intake air amount. The decreasing of the intake air amount prevents undesirable increase of the engine speed caused by the advancing of the ignition timing.

Abstract: The invention relates to a method for producing hot working gases for a gas turbine system. In a burner, combustion that generates hot combustion waste gas takes place.

Oxygen-enriched branched-off waste gas as well as fuel feed to the burner and form a combustion mixture that bums in the burner while forming the hot combustion waste gases. In order to improve the efficiency of the device, the oxygen-enriched branched-off waste gas heats the oxygen-containing gas.

Abstract: System and method for reducing temperature variation among heat dissipating components in a multi-component computer system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable speed compressor or a constant speed compressor is utilized to control the flow of refrigerant through the refrigeration system. The temperature variation among components is reduced by independently metering the mass flow rate of the refrigerant flowing into each component to compensate for the amount of heat load on each component. In this respect, the mass flow rate of the refrigerant entering into each of the evaporators is metered by valves located upstream from each of the evaporators.
