摘要： An exhaust by-pass system in an internal combustion engine provided with a turbocharger. The turbocharger is the so-called twin entry type having a pair of scroll passageways connected to two groups of cylinders of the engine, respectively. By-pass passageways are formed in a housing of the turbine of the turbocharger. The by-pass passageways are connected to scroll passageways, respectively at positions near their inlets. The by-pass passageways are opened or closed by a common by-pass control valve arranged in a tubular boss portion of the housing.

摘要： A boost pressure control system for an engine, by which the degree of opening of the air bypass valve is adjusted and on/off of a mechanical supercharger operation is controlled to obtain an appropriate boost pressure. In the system, the degree of opening of the air bypass valve is adjusted in accordance with the load of the engine, based on different characteristics selected in accordance with whether the operation of the supercharger is started or stopped. If the engine is operated in a non-boost region, when the supercharger is operating the degree of opening of the air bypass valve is made larger to reduce the compression work of the supercharger, and when the operation of the supercharger is stopped, the degree of opening of the air bypass valve is made smaller to ensure that the air flow through the supercharger maintains the rotation of the rotors of the supercharger.

摘要： A device for controlling an internal combustion engine which uses, as the fuel, a heavy fuel, a light fuel, an alcohol fuel and a mixture thereof, comprising a heavy fuel/light fuel ratio detector 39 capable of detecting the ratio of the heavy fuel and the light fuel, and an air-fuel ratio detector 41 for detecting the air-fuel ratio of the exhaust gas, wherein the amount of fuel injection is calculated based on the heavy fuel/light fuel ratio detector so that the air-fuel ratio becomes a target air-fuel ratio. The heavy fuel/light fuel ratio detector is diagnosed if it is in an abnormal condition based on a difference between the target air-fuel ratio and the air-fuel ratio detected by the air-fuel ratio detector while the engine temperature is in a particular temperature region. The heavy fuel/light fuel ratio detector can be correctly diagnosed if it is in an abnormal condition even when an alcohol-mixed fuel is used.

摘要： A boost pressure control system for an engine, by which a boost pressure of the engine is controlled in accordance with a load of the engine. The system controls the boost pressure in two different control modes, i.e., an acceleration mode and a normal mode, and when a degree of acceleration required becomes larger than a predetermined value, the acceleration mode is selected in which the boost pressure is made higher than in the normal mode. To avoid a sudden drop of the boost pressure, the system maintains the acceleration mode even after the completion of the acceleration, until the engine load becomes low enough that the boost pressure drops to the level at which the switching to the normal mode does not cause a sudden pressure drop.
