Abstract: A method for improving the effectiveness of filters by increasing accuracy of an estimate of particulate matter loading remaining in the filter after cleaning. In one embodiment, the disclosed method includes removing soot from the DPF by cleaning, and measuring parameters for a set of predetermined criteria. The amount of soot present in the DPF is then estimated based on delta pressure. The resulting estimated soot load value accounts for the noise factors such as ash loading after extended operation. The value is then used to adjust for future measurements of soot loading in the DPF after subsequent regeneration treatments and/or used to diagnose the effectiveness of the cleaning. The method can also be applied to diagnostics of the DPF. When discrepancies between DPSLE and model-based soot load estimate are observed in healthy regenerations, failure modes such as plugged filter, extreme ash loading or substrate melting can be detected.

Abstract: An SOx trap catalyst able to trap SOx contained in the exhaust gas is arranged in an engine exhaust passage upstream of an NOx storing catalyst in an internal combustion engine. When the SOx trap rate of the SOx trap catalyst falls, fuel is added in the exhaust gas flowing into the SOx trap catalyst to form in the SOx trap catalyst a region in which an air-fuel ratio becomes locally rich. SOx released from the SOx trap catalyst in this region can be trapped in the SOx trap catalyst at the downstream side once again without flowing out from the downstream end of the SOx trap catalyst.

Abstract: The catalyst smell reducing control in which the fuel cutoff is performed is not executed regardless of the catalyst smelling flag Fs1 equal to ‘1’ (step S140) when the vehicle speed V becomes less than the preset vehicle speed Vref (step S130) while the catalyst deterioration reducing control in which the fuel cutoff is prohibited is being executed (step S150). Such control prevents from executing the catalyst smell reducing control while the suspension of the catalyst deterioration reducing control and prevents performing the fuel cutoff after performing a fuel injection and performing the fuel injection again for a relatively short time in the internal combustion engine.

Abstract: A process for purifying exhaust gases includes the steps of collecting PMs, forcibly exhausting PMs, and purifying PMs. In the step of purifying PMs, PMs in exhaust gases are collected with a filter. In the step of forcibly exhausting PMs, PMs, which are collected on the filter, are exhausted by blowing a pressurized gas onto the filter, thereby forming PMs-containing gases. In the step of purifying PMs, PMs, which are contained in the PMs-containing gases, are purified by contacting an oxidizing agent with the PMs-containing gases, thereby removing the PMs from the PMs-containing gases by means of oxidation.

Abstract: When water is pumped manually to the overhead tank, the weight of the water is felt on the opposite end of the lever. Thus, an equal or heavier weights to counter that weight is thought of. This idea works on the output process but not on the input process. However, unlike conventional water pumps, C-M1 works on both processes using techniques (the invention) that employ the underlying principle of equilibrium or perfect balance. These techniques have resulted to the discovery of C-M1, a very powerful perpetual motion machine capable of using equal or heavier weights to counter the weights on the other end of the lever on both the input and output operations. Therefore, since it is perfectly balance, pumping out 1 cubic meter of 10 water per stroke through a 1.6-meter diameter 500-meter high pipe, with a total water weight of 1,000 tons, is simple and easy job for C-M1.
