摘要： An EGR-mixer system may include an exhaust gas recirculation valve and a venturi mixer. The venturi mixer may be constructed and arranged to facilitate condensation of water out of exhaust gas and/or intake air entering the EGR-mixer system after which the condensate may be collected and the exhaust gas and/or intake air may flow through the EGR-mixer system.

摘要： An electric supercharger includes an electric motor, a compressor wheel rotated by the electric motor, and a compressor housing. The compressor housing includes a first passage through which air is introduced, an introducing port connecting to an EGR device, a second passage through which at least one of air and EGR gas is flowed, a bypass passage through which at least one of air and EGR gas is flowed, and a bypass valve to open and close the bypass passage. When the bypass valve is opened, air introduced from the first passage and EGR gas introduced from the introducing port are flowed through the bypass passage to the internal combustion engine. When the bypass valve is closed, air introduced from the first passage and EGR gas introduced from the introducing port are compressed in the compressor wheel and flowed through the second passage to the internal combustion engine.

摘要： A valve reference position-learning device for an internal combustion engine, which is capable of accurately learning the reference position of a valve both before and after the warm-up of the engine, while properly reflecting thereon a deviation of the reference position caused by the thermal elongation of the valve and drive system after the warm-up of the engine. The valve reference position-learning device calculates and updates a learned value of the reference position of the wastegate valve both at and after the start of the engine, by first and second learnings, respectively. The learned value calculated by the first learning is stored as an existing learned value. Further, at the start of the engine, if the calculation of the learned value is not completed, the learned value is set to the existing stored learned value.
