Abstract: A method for controlling an engine having both an electronically controlled inlet device, such as an electronic throttle unite, and an electronically controlled outlet device, such as a variable cam timing system is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by coordination of the inlet and outlet device. This improved control is used to improve various engine control functions.

Abstract: The invention relates to a method and an apparatus for cleaning ambient air of a vehicular adsorption unit (8). The vehicle includes a combustion engine (1) and a passenger ventilation system (5, 6, 7, 8, 9, 10, 11). Adsorption takes place whether the engine (1) is running or not. During adsorption, a fan (11) forces ambient air from an inlet (6) to the ventilation system in a first direction, through an adsorption unit (8), and out of an outlet (10). To desorb when the engine is running, air is supplied to a heater (13). Heated air passes through the adsorption unit (8) to release pollutants and regenerate the unit. Pollutant-containing air passes through a second heater (4,16) and then through the first heater (13) to heat the ambient air. Finally, polluted air is drawn from the heat exchanger (13) to an intake conduit (3) of the engine (1).
Abstract: A system and method for controlling an internal combustion engine for low emissions include an inner feedback control loop to control the engine fuel/air ratio with feedback provided by a first exhaust gas sensor and an outer feedback control loop that modifies the fuel/air ratio reference provided to the inner feedback control loop based on feedback signals provided by the first exhaust gas sensor and a second exhaust gas sensor. The fuel/air ratio reference signal controller adapts to the oxygen storage capacity of the catalyst by modeling the catalyst as an integrator with an unknown gain and estimating the catalyst gain based on the first and second exhaust gas sensor signals. Using the estimated catalyst gain, an adaptive controller gain factor is determined and subsequently used to determine the fuel/air ratio reference signal provided to the fuel/air ratio controller of the inner feedback control loop.

Abstract: A method and a system for improved reductant delivery to an exhaust gas aftertreatment device for a lean burn internal combustion engine exhaust are presented. The system includes a heated evaporator unit into which a mixture of reductant and air in injected, wherein the mixture is vaporized and introduced into the exhaust gas aftertreatment device. Introducing the reductant mixed with air into the heated evaporator unit prevents lacquering and soot deposits on the heated element housed inside the unit, and also speeds up the vaporization process due to better reductant distribution thus reducing system response delays and improving conversion efficiency of the exhaust gas aftertreatment device. The reductant delivery system is further improved by adding a catalyst to it, and by preventing the reductant and air mixture from coming into direct contact with the surface of the heating element.

Abstract: A method for preventing a valve orifice from switching to the small size when a high build gradient is required includes briefly bleeding off a small amount of fluid at the upstream side of the valve. This momentarily reduces the pressure difference when beginning the pressure build. After the valve is opened with the large orifice, the fluid flow through the valve prevents a high pressure difference. The resulting build with the large orifice has the maximum pressure gradient.

Abstract: A multifunctional third row seating assembly that is capable of moving between two seating positions, as well as moving between split passenger seating configurations and between seating and storage positions. In the storage position, the third row seating assembly forms a true flat floor in combination with a second row seating assembly. The third row seating assembly includes a seat cushion and a seat squab coupled to it and mounted to the vehicle such that the third row seating assembly can be pivoted in an elliptical movement between a forward and a rearward seating position. The third row seat cushion is also latched such that it can be released and flipped over from a front longitudinal axis to fit into a foot rest area of the vehicle. The third row squab can then be folded down to form a flat floor. The third row squab is also constructed in two sections, so that it is capable of forming a bench seat or a split seat.

Abstract: A method of compensation for current-sensor gain errors in an electric machine drive 14 includes a high frequency carrier signal electrically injected into the electric machine 14. A current-sensor signal of the electric machine 14 is determined. The current-sensor signal is separated into current-sensor carrier signal negative and current-sensor carrier signal positive sequence reference frames. A proportional compensator signal for one of the current-sensor carrier signal reference frames is generated in a feedback loop 24. A magnitude signal of another one of the current-sensor carrier signal reference frames is generated in a different feedback loop 26.
Abstract: A method of detecting leakage currents in a high voltage battery pack system reduces detection error caused by fluctuations in battery pack voltage during the detection process. The voltages of the individual modules forming the battery pack are separately and simultaneously measured during each measurement of leakage current on the high and low sides of the leakage point. Measurements of individual module voltages are combined with the simultaneous current leakage measurements to calculate leak resistance.

Abstract: A method is presented for estimating an amount of ammonia stored in a urea-based SCR catalyst based on a dynamic model of the catalyst. The model takes into account chemical and physical properties of the catalyst, such as catalyst volume, the number of available ammonia storage cites, adsorption and desorption dynamics, as well as poisoning, thermal aging, and different catalyst operating temperatures, and generates the estimate based on a measured or estimated amount of NOx in an exhaust gas mixture upstream of the catalyst, an amount of reductant injected into the catalyst to facilitate NOx reduction, and on a measured value of NOx in an exhaust gas mixture downstream of the catalyst. The estimated ammonia storage amount is then used to control the amount of reductant injected into the catalyst to maintain desired ammonia storage amount such that maximum NOx conversion efficiency coupled with minimum ammonia slip are achieved.
