In one example, the method may include during a first operating mode in which catalyst diagnostics are not carried out, adjusting air-fuel ratio based on both the upstream and downstream exhaust gas oxygen sensors, where air-fuel ratio adjustment responsiveness to the downstream sensor is reduced as the catalyst performance degrades; and during a second operating mode that includes catalyst diagnostics, adjusting air-fuel ratio based on at least the downstream exhaust gas oxygen sensor, where said air-fuel ratio adjustment responsiveness to the downstream sensor is temporarily increased from said reduction generated during the first operating mode.

Abstract: One concept relates to a method of controlling fuel reforming within an internal combustion engine exhaust line. Fuel injections are controlled using a predicted temperature, the predicted temperature being a temperature that would occur at some point in the future if predetermined assumptions are met. Preferably, the prediction is made using a model that includes terms for hydrocarbon storage and subsequent reaction within the reformer. The method improves reformer temperature control, particularly over periods during which the fuel supply to the reformer is pulsed. The scope of the invention also includes methods wherein a temperature is not specifically predicted, provided the control method takes into account hydrocarbon storage and subsequent reaction.

Abstract: Every time a specified period of time is counted during execution of filter regeneration control, a PM remaining amount every time that the specified period of time passes is estimated by subtracting the product of the specified period of time, a PM removal rate per unit time, and a PM remaining amount at the point when the specified period of time started to be counted from the PM remaining amount at the point when the specified period of time started to be counted. As a result, the PM remaining amount during execution of filter regeneration control which oxidizes and removes particulate matter that has accumulated on a particulate filter is estimated with greater accuracy.

Abstract: A clearance volume valve for controlling cylinder compression at varying engine speeds in a steam engine. At the injector of each cylinder, a clearance volume valve is hydraulically operated in response to changes in engine RPMs to thereby control opening and closing of an inlet to a sealed tube that extends from each cylinder of the engine.

At higher engine RPMs, the clearance volume valve is hydraulically operated to close the tube inlet, thereby reducing the total clearance volume and raising the cylinder compression for greater efficiency at higher engine speeds.

Abstract: This invention is a water producer that extracts water from the air. One embodiment of the invention adiabatically compresses and heats the air. The heated air is cooled through a counter-flow heat exchanger so that it becomes supersaturated and water condenses. The air is then cooled further and passed back through the heat exchanger to recover its former heat. It then passes through an adiabatic expander to recover energy. A second embodiment utilizes a unique isothermal compressor/expander to compress the humid air isothermally so that the air becomes supersaturated with water, and the water condenses. The air is then cooled to remove the heat of condensation of the water and returned to the isothermal compressor/expander to recover energy. A third embodiment draws in humid air through a counter-flow heat exchanger to cool it down below its dew point so that water is collected.
