Abstract: In a supercharged internal combustion engine having a plurality of cylinders which are arranged in at least one cylinder bank, preferably a V-type engine with an exhaust gas turbocharger including a compressor, which is arranged in an intake line of the internal combustion engine and a turbine which is arranged in an exhaust gas collection line, the exhaust gas of a plurality of cylinders of the cylinder bank is combined in an exhaust gas collection line, while at least one cylinder of a cylinder bank has a separate exhaust gas line which bypasses the exhaust gas turbocharger and joins the exhaust gas line downstream of the turbine.

Abstract: In a method of controlling an exhaust gas turbocharger of an internal combustion engine charged by a compressor wherein as guide value for the control an operating point of the compressor is used, the operation of each cylinder bank of the internal combustion engine is controlled by dividing the total air mass flow by the number of cylinder banks and an equal amount of desired air mass flow is assigned to each cylinder bank and if the air mass flow to any of the cylinder banks is smaller than that to the other or others air from the other cylinder bank or banks is supplied to the one cylinder bank via a compensation arrangement so that the air mass flows to all cylinder banks are essentially equal.

Abstract: In a method of controlling an exhaust gas turbocharger of an internal combustion engine charged by a compressor wherein as guide value for the control an operating point of the compressor is used, the operation of each cylinder bank of the internal combustion engine is controlled by dividing the total air mass flow by the number of cylinder banks and the same amount of desired air mass flow is assigned to each cylinder bank and if the air mass flow to any of the cylinder banks is smaller than that to the other or others air from the other cylinder bank or banks is supplied to the one cylinder bank via a compensation arrangement so that the air mass flow to all cylinder banks is essentially the same.

Abstract: There is described a pharmaceutical composition comprising liposomes and sodium cromoglycate. There is also described an aqueous suspension comprising sodium cromoglycate partitioned between a free aqueous phase and a liposome phase. There is further described a method for making the compositions and their use in the treatment of allergic conditions, e.g., asthma.
