Embodiment Construction

[0020] figure 1 Indicates a large engine of an invention. Here it can be a two-stroke large diesel engine. The basic structure and operating principle of such engines are well known, and they can be used, for example, as ship drives or generator drives.

[0021] figure 1 The engine shown in is equipped with an exhaust gas turbocharger 1, whose turbine 2 works with the exhaust gases produced during combustion in the engine cylinders, whose compressor 3 compresses the air sucked in via the air filter 4, which is fed as charge air cylinder. The turbine 2 is connected via a supply line to an exhaust gas collecting line 5 through the respective cylinder, to which the exhaust gas outlet of the respective cylinder is connected. In the illustrated embodiment, the exhaust gas collecting duct extends over all cylinders of the engine which are arranged side by side. The air compressed by the compressor 3 is fed into a charge air container 6 to which at least one set of associated cy...

Abstract

In A large-sized engine having a supply air container 6, supply air can be added into the supply air container by an exhaust turbocharger 1 and / or an auxiliary blower 10 having an impeller 13 drivableby a motor 9, and the supply air can be conditioned by an intercooler and a liquid drop separator provided in a post stage. A conditioning housing 8 is provided in the post stage of the exhaust turbocharger 1, and the housing has a section for the intercooler and a section for the liquid drop separator. A blower space of the auxiliary blower 10 is connected with the section on the inlet side. Each blower space and each adjoining section have at least one common wall including an inlet of the blower space.

Description

technical field [0001] The invention relates to a large engine, especially a two-stroke large diesel engine. Background technique [0002] In known devices of this type, each auxiliary blower has its own blower housing, which has on the suction side and the pressure side a connecting pipe connection with a connecting flange and is flanged with it to the regulating valve. housing or charge air container. This not only requires high assembly effort, but also results in a very space-intensive and, in particular, very unstable, vibration-sensitive structure. Only auxiliary blowers with blower wheels of a smaller diameter can therefore be used. However, such blower wheels require high rotational speeds, which often necessitates the use of a gearbox between the electric motor and the blower wheel, thus further increasing the outlay and space requirements. Contents of the invention [0003] It is therefore the object of the invention to improve a device of the type mentioned a...
