摘要： An internal combustion engine control method controls an internal combustion engine equipped with an exhaust gas temperature variation factor unit that varies the temperature of an exhaust gas of the internal combustion engine, an exhaust heat recovery device disposed in an exhaust passage downstream of the exhaust gas temperature variation factor unit and that recovers the heat from the exhaust gas into a refrigerant that cools the internal combustion engine, and a refrigerant flow rate adjustment unit that adjusts a flow rate of the refrigerant that passes through the exhaust heat recovery device. The internal combustion engine control method estimates a boiling margin, which is a parameter related to a thermal margin when the refrigerant boils in the exhaust heat recovery device, and determines whether to execute a boiling avoidance process in accordance with the boiling margin.

摘要： A cooling system controller controls a cooling system at least having a coolant pump (3) configured to supply a coolant to an internal combustion engine, a heat radiator (9) configured to cool the coolant, and an exhaust heat recovery system (6) configured to perform in heat exchange between the exhaust gas and the coolant. In addition, the cooling system controller (12) has a unit configured to control the coolant flow rate, a unit (13) configured to obtain a coolant temperature or pressure of the internal coolant passage of the engine, and a unit configured to obtain an internal coolant temperature or pressure of the exhaust heat recovery system. Furthermore, the coolant flow rate is restricted at a cold start of the internal combustion engine, and the restriction of the coolant flow rate is released on the basis of the coolant temperature or pressure of the engine coolant passage and the internal coolant temperature or pressure of the exhaust heat recovery system.

摘要： An engine exhaust apparatus includes an exhaust passage for flowing exhaust gas emitted from an engine, a flow rectifier for rectifying the flow of the exhaust gas, and an exhaust heat recovery unit disposed in the exhaust passage downstream of the flow rectifier. The exhaust heat recovery unit is provided with an exhaust heat recovery portion and a cooling portion to cool the exhaust heat recovery portion. The engine exhaust apparatus further includes a first diameter reducing portion gradually reduced in diameter toward the exhaust heat recovery unit from the flow rectifier, and a second diameter reducing portion gradually reduced in diameter toward the downstream from the exhaust heat recovery unit.

摘要： An exhaust device of an engine, with an exhaust path to lead exhaust gas discharged from the engine to outside, the exhaust device comprising: an exhaust heat collector being configured to collect heat from the exhaust gas, and a cooling part being configured to cool down the exhaust heat collecting part from an outer peripheral side via a cooling fluid; and an exhaust gas flow controlling member in a cylindrical shape, comprising an inlet part and an outlet part where the inflow of the exhaust gas is discharged to an upstream side of the exhaust heat collecting part. An opening diameter of the outlet part is arranged to be smaller than an outer diameter of the exhaust heat collecting part. The exhaust gas flow controlling member is placed so that an open end of the outlet part opposes a central portion of an upstream end plane of the exhaust heat collecting part. The open end of the outlet part and the upstream end plane of the exhaust heat collecting part are a predetermined distance apart.
