摘要： The invention relates to an aerosol separator for separating aerosols in a blow-by gas, which comprises at least one feed opening for feeding a blow-by gas provided with aerosols, an outlet opening for discharging a blow-by gas cleaned of aerosols, at least one outflow opening for releasing aerosols removed from the blow-by gas, and which is arranged between a flow path of the at least one feed opening and the outlet opening, and a plurality of projections for configuring the flow path running from the at least one feed opening to the outflow opening in a meandering manner, in order to decelerate the blow-by gas which enters the feed opening and which is provided with aerosols, in terms of its flow rate. The separator is characterized in that the projections in their end region, around which blow-by gas flows, have a portion with increasing projection width.

摘要： A gas engine includes a mixing unit for mixing two gas components, which are fed to one or more combustion chambers of the gas engine, in particular for mixing fuel gas and charge air, as well as two compressors. By way of the compressors, the two gas components are separately compressed before the two gas components are fed to the mixing unit. Both compressors are driven by a turbine arranged in the exhaust gas system of the gas engine.

摘要： A controller for a common-rail injection system includes a plurality of fuel injectors, a common fuel supply line for the fuel injectors, a high-pressure pump for supplying the common fuel supply line with fuel, and a pressure sensor for determining the pressure in the common fuel supply line. A determination unit evaluates data of the pressure sensor and, from the pressure drop caused by an injection in the common fuel supply line, determines the fuel quantity actually injected during this injection or a value derived therefrom. An adaption unit uses the results of the determination unit in order to adapt the actuation of the fuel injectors. The determination unit carries out at least one test injection, and the actually injected fuel quantity or a value derived therefrom is effected by way of the test injection or injections.
