摘要： A method for improving exhaust after treatment initial warm up during engine starting is presented. In one example, the method adjusts an engine air flow amount to a level where a desired substantially constant heat flux is provided by the engine to an exhaust after treatment device. The method may reduce fuel consumption and a need for a vacuum pump to provide vacuum to vacuum consumers of a vehicle during exhaust after treatment heating.

摘要： A method for controlling engine vacuum production is disclosed. In one example, one or more air sources to an engine intake manifold are closed so as to increase an amount of air drawn from another air source. The method may increase a rate of vacuum supplied to a vacuum actuated device so as to improve operation of the vacuum actuated device.

摘要： A fuel delivery system for a multi-fuel internal combustion engine and an approach for operating the fuel delivery system are provided. The fuel delivery system can be operated in two or more different fuel delivery modes according to operating conditions of the engine or fuel delivery system. A first example mode can be performed to concurrently deliver two or more fuels to the engine. A second example mode can be performed to transfer fuel from a first fuel storage tank to a second fuel storage tank. A third example mode can be performed to supply a fuel from a first fuel storage tank to at least two fuel injectors of each cylinder of the engine. In some embodiments, the various modes of operation may be selected by varying a fuel pressure that is provided by the fuel delivery system.

摘要： A vacuum source arbitration system is disclosed. In one example, vacuum is supplied to a vacuum reservoir via an ejector during a first condition, and vacuum is supplied to the vacuum reservoir via an engine intake manifold during a second condition. The approach may provide a desired level of vacuum in a reservoir while reducing engine fuel consumption.
