摘要： A method and a computer program for recognizing and differentiating a flow rate error and a dynamic error of an exhaust gas recirculation system (EGR) of an internal combustion engine. Measured and modeled EGR mass flow signals are each subjected to bandpass filtering using time constants optimized for determining flow rate errors and bandpass filtering using time constants optimized for determining dynamic errors. The energy is determined for each of the filtered signals and an energy quotient is computed between the energies of the signals filtered for dynamic errors and the signals filtered for flow rate errors. A dynamic error and a flow rate error of the exhaust gas recirculation may be recognized and differentiated from one another on the basis of the energy quotients.

摘要： Methods are provided for controlling a vehicle engine to improve engine efficiency utilizing onboard water condensate. In one example, condensate is collected from cooling air routed into an engine, and injected into one of a plurality of locations based on engine operating conditions to keep NOx in combustion gases below desired amounts and to avoid ignition knock in said engine. In this way, condensate build-up in the CAC is advantageously utilized, engine performance and efficiency may be improved, and harmful emissions may be reduced.

摘要： A method for desulphurizing an exhaust-gas recirculation flow of an internal combustion engine supplied to the internal combustion engine on the fresh-air side includes branching a partial exhaust-gas flow from the exhaust-gas flow of the internal combustion engine. At least one reactant is supplied to the partial exhaust-gas flow that splits to form ammonia, and the thus laden partial exhaust-gas flow is supplied partially, as an exhaust-gas recirculation flow, to the fresh-air side and partially, as an aftertreatment partial flow, to an exhaust-gas aftertreatment system. The flow rate of the exhaust-gas recirculation flow supplied to the fresh-air side and the flow rate of the aftertreatment partial flow supplied to the exhaust gas aftertreatment system are predefined and/or varied by a regulating device as a function of at least one operating parameter that defines the respective operating state of the internal combustion engine.

摘要： In an EGR system that introduces an EGR gas to a vicinity of an inlet of a compressor in an intake passage, prevention of erosion of an impeller by condensed water generated in an EGR passage, and restraint of pressure loss of intake air are made compatible. An introduction port for an EGR gas formed in a wall surface of the intake passage in a vicinity of the inlet of the compressor and an exhaust passage are connected by the EGR passage. The EGR passage is provided with an EGR valve, and an exhaust throttle valve is provided downstream of a position where the EGR passage is connected in the exhaust passage. By a control device that controls the EGR valve and the exhaust throttle valve, respective opening degrees of the EGR valve and the exhaust throttle valve are controlled in accordance with a flow rate of fresh air that flows to the compressor, and a velocity of the EGR gas that flows out into the intake passage from the introduction port for the EGR gas is changed so that the EGR gas flows toward a center portion of the impeller of the compressor.

摘要： Methods and systems are provided for adjusting a reference voltage for an intake manifold oxygen sensor based on ingestion of hydrocarbons from a fuel system canister and/or an engine crankcase. During conditions when purge or crankcase ventilation hydrocarbons are ingested in the intake aircharge, the intake oxygen sensor is transitioned from operating at a lower reference voltage to a higher reference voltage where the effects of the ingested hydrocarbons on the sensor output are nullified. An EGR dilution of the intake aircharge is estimated based on the output of the sensor at the higher reference voltage while an amount of hydrocarbons ingested is estimated based on a difference between sensor outputs at the higher and lower reference voltages.
