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

A large engine with a charge air container (6) which can be operated by means of an exhaust gas turbocharger (1) and / or by means of at least one blower with a motor (9) The auxiliary blower (10) of the impeller (13) is supplied with charge air, which can be conditioned by means of a charge air cooler with a downstream droplet separator and with a Regulating housing (8) behind the device (1), which has at least one compartment (19) for a charge air cooler and at least one compartment (11) for a droplet separator, an auxiliary At least one blower chamber (12) of the blower (10) is connected to it on the inlet side, in such a large engine a very compact and vibration-resistant construction can be achieved in such a way that each blower chamber (12 ) and corresponding adjacent compartments (11) have at least one common wall (15) containing the inlet of the blower chamber (12).

Description

technical field [0001] The invention relates to a large engine, in particular a two-stroke large diesel engine, the cylinders of which are connected in groups at least to a common charge air container, which can be operated by means of an exhaust gas turbocharger and / or Charge air is supplied by means of at least one auxiliary blower with a blower wheel that can be driven by an electric motor, the charge air being conditioned by means of a charge air cooler with a downstream (downstream) droplet separator, Also provided is an adjustment housing arranged behind the exhaust gas turbocharger, which has at least one compartment for a charge air cooler and at least one compartment for a droplet separator, at least one compartment for an auxiliary blower A blower chamber is connected to it on the inlet side. 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 connectin...
