摘要： A method of controlling the fueling rate of a compression ignition engine having an exhaust gas recirculation system (EGR) and a turbocharger. The method includes the steps of predicting the exhaust gas air/fuel ratio as a function engine operating characteristics and the operator-requested fueling rate. This value is compared to an air/fuel limit value stored in a table of values indexed by engine operating characteristics. The air/fuel limit is the value below which visible smoke occurs. The predicted air/fuel ratio is compared to the air/fuel ratio limit and either (1) the fuel is delivered at the requested rate, (2) the start of injection timing is modified and the fuel is delivered at the requested rate or (3) the fueling rate is limited as a function of the requested fueling rate and measured or determined engine operating parameters.

摘要： A method of estimating the airflow into a compression ignition engine having an exhaust gas recirculation system (EGR) and a variable geometry turbocharger (VGT). The method includes the steps of generating an EGR flow value as a function of the intake manifold pressure (MAP), exhaust manifold pressure (EXMP), position of the exhaust gas recirculation valve, and temperature of the gas flowing through the EGR. From this calculation, the method generates an intake airflow value (MAF) as a function of the EGR flow value and the intake aircharge temperature. The intake airflow value is used, in turn, to control the position of the EGR valve. The disclosed method thereby eliminates the necessity for a MAF sensor.

摘要： A method of estimating the actuator position of a variable geometry turbocharger (VGT) of a compression ignition engine having an exhaust gas recirculation (EGR) system. The method includes the steps of determining the exhaust manifold temperature (T.sub.2), determining the mass flow rate (W.sub.2t) through the turbocharger turbine, determining the exhaust manifold pressure (p.sub.2), determining the turbine back-pressure (p.sub.exs), and generating a VGT actuator position estimate (.alpha..sub.vgt) as a function of W.sub.2t, T.sub.2, p.sub.2, and p.sub.exs. The estimated VGT actuator position is then used to generate an error term indicative of the difference between the estimated and desired VGT actuator position. The error term can then be used to drive the VGT actuator to its desired position to regulate the intake manifold pressure.

摘要： A method of reducing turbo lag in a compression ignition engine having an exhaust gas recirculation system (EGR) and a variable geometry turbocharger (VGT). The method includes the steps of determining an intake manifold pressure and intake manifold mass airflow setpoint, MAPd and MAFd, as a function of the current engine speed and requested fueling rate (Wf,REQ). The method further includes modifying the setpoints by a transient governor to generate modified setpoints, MAFc and MAPc, as a function of MAFd and MAPd, respectively, and feeding the modified setpoints to the controller to drive the turbocharger and EGR valve to the desired setpoints, thereby maximizing the amount of fresh air admitted to the engine during transient operation. Another embodiment of the method for reducing turbo lag coordinates the controller gains between the EGR and VGT. The method speeds up the MAF response by using multivariable control of both the EGR and VGT to aggressively regulate airflow to the desired setpoint.

摘要： A method and apparatus of controlling the airflow into a compression ignition engine having an exhaust gas recirculation (EGR) system and a variable geometry turbocharger (VGT). The control strategy includes the steps of measuring the intake manifold pressure and exhaust manifold pressure, and using these values, estimating the EGR flow fraction. The EGR flow fraction is then used in a proportional plus integral feedback control loop to generate position commands for the EGR valve. Similarly, the intake manifold pressure signal is used in a proportional plus integral feedback control loop to generate position commands for the VGT. In this way, the EGR valve is used to regulate the EGR flow fraction to a desired value and the VGT turbine is used to regulate the intake manifold pressure to a desired value.

摘要： A method to control a hybrid electric vehicle includes operating a compression ignition engine based on an engine-on request, and performing an exhaust aftertreatment procedure when a fraction of an engine-on time is greater than an aftertreatment condition threshold. A vehicle has a compression ignition engine with an exhaust aftertreatment system, and a controller. The controller is configured to: (i) operate the engine based on an engine-on request, and (ii) perform an exhaust aftertreatment procedure for the vehicle when an engine-on fraction for a designated time is greater than an aftertreatment condition threshold. A computer readable medium having stored data representing instructions executable by a controller to control a vehicle includes instructions for operating the engine based on an engine-on request, and instructions for performing an exhaust aftertreatment procedure for the vehicle when an engine-on time fraction is greater than an aftertreatment condition threshold.
