摘要： A control device applied to an internal combustion engine (20) including a first supercharger (50) and a second supercharger (60) disposed in series includes: a supercharging-system controlling portion (11) for controlling a boost pressure; a cooling-system controlling portion (12) for controlling a flow rate of coolant circulating through an intercooler (71); and a valve defect detection portion (13) for detecting that a compressor bypass valve (32) is stuck in an opened state. When the valve defect detection portion (13) detects that the compressor bypass valve (32) is stuck in the opened state, the cooling-system controlling portion (12) increases a driving amount of an electric pump (72) so as to increase a flow rate of the coolant circulating through the intercooler (71).

摘要： An internal combustion engine system includes an internal combustion engine, an exhaust system, an exhaust gas recirculation circuit and a turbocharger including a first turbine interacting with a first compressor for charging air to the internal combustion engine. An exhaust gas recirculation passage is arranged to divert exhaust gases from the internal combustion engine upstream the first turbine and to debouch the exhaust gases downstream the first compressor. The internal combustion engine includes a bleed air channel which is located to divert compressed air at a location in or downstream from the first compressor and upstream of the internal combustion engine. A second turbine is arranged for receiving bleed air from the bleed air channel to recover energy from the bleed air channel. A vehicle including such an internal combustion engine system is also provided.

摘要： An exhaust gas pressure regulator for a combustion engine includes a regulator housing and an inner diffuser assembly arranged inside the regulator housing so that an exhaust gas flow duct is formed between an inner surface of the regulator housing and an outer surface of the inner diffuser assembly. The inner diffuser assembly includes a front portion and a regulating piston that is moveable relative to the front portion and the regulator housing between an idle position in which the exhaust gas flow duct is open, and a pressurized position in which the regulating piston at least partly closes the exhaust gas flow duct. The inner diffuser assembly includes at least one throttled flow passage between the gas flow duct and an exhaust gas pressure chamber defined by the regulating piston and an interior surface of the front portion.

摘要： An exhaust-flow-rate control valve 1 for controlling a flow rate of exhaust gas flowing through an exhaust flow passage includes: a valve rod 2; a valve body 3 having a flat plate shape and configured to rotate about the valve rod 2; and a valve housing 4 having a cylindrical shape and defining a part of the exhaust flow passage inside the valve housing. A valve seat surface 41 extending along a direction intersecting with an axial direction of the exhaust flow passage and being configured to make contact with an outer peripheral portion 31 of the valve body 3 in a fully-closed state in which an opening degree of the valve body 3 is zero degree, and a flow passage surface 42 extending along the axial direction of the exhaust flow passage and defining a passage region R through which the exhaust gas passes between the flow passage surface 42 and the outer peripheral portion 31 of the valve body 3 in a valve-open state in which the opening degree of the valve body 3 is greater than zero degree are formed on an inner peripheral surface of the valve housing 4. The passage region R of exhaust gas increases slowly while the valve body transitions from the fully-closed state to a predetermined valve-open state in which the separation distance between the valve body 3 and the end portion 42b of the flow passage surface 42 is shortest.
