摘要： A method for controlling charge flow in an internal combustion engine includes operating an engine having a VGT. The method includes determining a target and current charge flow and EGR flow. The method further includes determining an error term for the charge flow and the EGR flow, and determining an exhaust pressure feedback command in response to the error terms. The exhaust pressure feedback command is combined with an exhaust pressure feedforward command, and the VGT is controlled in response to the exhaust pressure feedback command. The method additionally includes determining the exhaust pressure feedback command in response to a current EGR valve position. The method further includes controlling an EGR flow rate with the EGR valve at relatively closed EGR valve positions, and controlling the EGR flow rate with exhaust pressure at relatively open EGR valve positions.

摘要： A fuel system has a source of fuel coupled to a plurality of fuel injectors via a fuel rail. The system is operable to estimate a quantity of fuel injected into an internal combustion engine by disabling fuel flow from the source of fuel to the fuel rail, and monitoring a fuel request corresponding to a request for delivery of fuel by the fuel system to the engine produced by the engine. If the fuel request is below a threshold fueling level a selected fuel injector is controlled to inject a selected quantity of fuel from the fuel rail into the engine while inhibiting fuel injection the remaining fuel injectors, fuel rail pressure is sampled, a drop in the fuel rail pressure, resulting from injection of the selected quantity of fuel, is determined from the fuel rail pressure samples, and the quantity of fuel injected by the selected injector is determined as a function of the drop in fuel rail pressure.

摘要： A fuel system has a fuel rail containing pressured fuel coupled to a plurality of fuel injectors. The system is operable in one embodiment to adjust fuel injector on- times by selecting one of the fuel injectors, determining a critical on-time for the selected injector corresponding to a minimum on-time duration to which the selected fuel injector is responsive to inject a discernable amount of fuel, generating an on- time for the selected fuel injector, determining an adjusted on-time for the selected fuel injector based on the generated on-time for the selected fuel injector, the critical on-time for the selected fuel injector and a reference critical on-time, and activating the selected fuel injector for the adjusted on-time to inject fuel into the engine. Alternatively or additionally, the adjusted on-time may be based on one or more estimated fuel injection quantities injected by the selected fuel injector.
