摘要： A method for providing intake air to an engine in a vehicle includes forming a mixture of fresh air and treated exhaust, and compressing the mixture upstream of a first throttle valve coupled to an intake manifold of the engine. The method further includes, during a higher engine-load condition, admitting the mixture to the intake manifold via the first throttle valve, and, during a lower engine-load condition, admitting fresh air to the intake manifold via a second throttle valve.

摘要： A method for controlling the air/fuel ratio of an internal combustion engine uses a manifold pressure sensor and an exhaust gas recirculation system having an orifice and a exhaust pressure sensor located upstream of the orifice. Both the manifold pressure sensor and the exhaust pressure sensor are sampled synchronously with a frequency proportional to the firing frequency of the engine and then filtered to eliminate unwanted frequencies. The sampled signals obtained then have the necessary bandwidth needed for closed loop control of the exhaust gas recirculation flow and engine air/fuel ratio control.

摘要： A method for controlling mode transitions, such as from stratified to homogeneous mode, in a direct injection engine adjusts an intake manifold outlet control device, such as a cam timing, to rapidly control cylinder fresh charge despite manifold dynamics. In addition, a coordinated change between an intake manifold inlet control device, for example a throttle, and the outlet control device is used to achieve the rapid cylinder fresh charge control. In this way, engine torque disturbances during the mode transition are eliminated, even when cylinder air/fuel ratio is changed from one cylinder event to the next.

摘要： Techniques are described for displaying a list of items while simultaneously depicting how the items satisfy multiple criteria. A list of visual indicators is displayed in an order. The order indicates how the items satisfy a first criteria. For example, the list of items may be books displayed in alphabetical order. The order indicates how the titles rank alphabetically. While retaining the order, information is displayed to visually indicate how the items satisfy other criteria selected by the user. The user may select other criteria, and information is displayed to indicate how the items satisfy the other criteria. A page is downloaded by a browser on a client. The browser executing a page generates visual indications of how items satisfy the multiple criteria in response to user selection of the criteria.
