摘要： A method for regenerating a diesel particulate filter (10) in the exhaust gas system of a diesel engine (5) is disclosed in which particulate matter is burned by increasing the temperature in the diesel particulate filter (10). Regeneration is carried out in a coordinated manner by: switching on electrical loads; at least partially closing the EGR valve, while adapting the pilot injection to prevent combustion noise exceeding an acceptable level; discontinuing feedback of boost pressure control via variable turbine geometry, when such feedback is present; restricting the fresh air supply to provide a desired intake pressure (depends on the speed and load); lessening the intake restriction to increase the intake pressure when the operator demands increased power or when the air/fuel ratio falls below a predetermined minimum value; increasing fuel supply as a function of the intake pressure, the pedal position and/or the engine speed when the fuel supply is not automatically controlled in some other way; and injecting post fuel during the expansion stroke when operating temperature of catalytic converter has been reached.

摘要： The invention relates to a method for interrupting the regeneration of a particulate filter in the exhaust gas system of a diesel engine to protect the filter against destructive overheating. In this case, an electronic control unit calculates a desired mass air mass flow rate (MAFdes) based on engine speed (n), fuel supply (Fq) to the engine, and air/fuel ratio (A/Fdes). A mass air flow rate regulator controls the position of an exhaust gas recirculation (EGR) valve as a function of the difference between the desired mass air mass flow rate (MAFdes) and the measured mass air flow rate (MAFmes). An intake manifold absolute pressure controller adjusts the position of an intake throttle valve as a function of the difference between the measured intake manifold absolute pressure (MAPmes) and the modified intake manifold absolute pressure (MAPmod). MAPmod is determined by a coordination module, based on the mass air flow rate error and other parameters.

摘要： A filter used to remove particulates from a diesel engine exhaust is regenerated by increasing the exhaust temperature to achieve burn off of the accumulated particulates. Regeneration of the filter is inhibited when the sensed level of fuel in a diesel fuel tank for the engine falls below a first threshold level. Optionally, filter regeneration may be initiated when the sensed fuel level is between the first threshold and a higher threshold, and the load level of particulates accumulated in said filter is above a preselected, relatively high load level. Increase of the exhaust temperature to achieve burn off may be achieved by a variety of techniques, including throttling the intake of said engine, reducing the oxygen content in the exhaust gases delivered to said engine, closing an EGR valve of said engine, or performing post injection of fuel in the engine's combustion cylinders.

摘要： A method for determining the load on an internal combustion engine exhaust particulate filter optimizes filter regeneration by determining the portion of the filter load constituted by accumulated ash. In one technique, the ash load is determined by recording the lowest value of DPF load over a time or distance interval. In another technique, an estimate is made of the amount of load remaining at each of a plurality of DPF regeneration events; the amount of remaining load immediately following the regeneration event corresponds to the amount of accumulated ash in the DPF. DPF load estimation is performed using equations for laminar or turbulent flow in pipes. These equations establish a linear or quadratic relationship between the flow through the DPF and the pressure drop measured across it.

摘要： An Electronic Engine Controller (EEC) which controls operation of an engine employs a switching type oxygen sensor to determine the composition of exhaust gas produced by the engine. The EEC enhances the signal received from the oxygen sensor to generate quantitative information from the qualitative information received from the oxygen sensor. The EEC utilizes the enhanced information from the oxygen sensor to adapt Transient Fuel Control (TFC) parameters. The EEC detects a transient, quantifies the transient in terms of two TFC parameters and adapts the TFC parameter employing fuzzy-logic controls.

摘要： The invention relates to the starting of an internal combustion engine. The engine is coupled to an exhaust aftertreatment device that has a minimal threshold temperature for proper operation. Within a certain period of time after engine start, the load on an electrical generator driven by the engine is increased. Also, the air intake is throttled to reduce the intake manifold pressure to a target pressure. Both measures provide faster engine and catalyst warm-up and, thus, reduced emissions, particularly for a diesel engine in connection with an oxidation catalyst.

摘要： A method and a regulating arrangement (10) for heating the cab (21) of a vehicle is described. In the event of a start in a cold environment, a heating program is carried out to heat the cab (21) more rapidly, if the diesel engine temperature, measured by a temperature sensor (15), is below a predetermined value. The supply of air to the diesel engine is reduced via the throttle valve (13) to set a currently predetermined intake pressure. If the driver demands a higher acceleration of the vehicle by actuating the accelerator pedal, throttling can be temporarily canceled. When the engine temperature has exceeded a second value, the heating program is terminated and the engine control (10) returns to normal operation. In order to assist the heating phase, in addition, the exhaust-gas recirculation valve (17) may be closed and electrical consumers switched on.

摘要： A diesel engine equipped with an exhaust gas particulate filter includes a control system that reduces exhaust gas smoke emissions normally resulting from an extended period of engine idling. The control method periodically raises the exhaust gas temperature in order to purge the particulate filter of water and hydrocarbons that build up during extended engine idling and cause exhaust smoke. A timer records the elapsed period during which the engine remains at idle and the exhaust temperature is below a threshold level. When the recorded time period exceeds a preselected value, the filter is purged by elevating the exhaust gas temperature to a level sufficient to oxidize the gaseous hydrocarbons and evaporate any water that may have accumulated in the filter.

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.
