Abstract

A turbocharge arrangement especially for a two-stroke diesel engine comprises at least one turbocharger (1) driven by the exhaust gasses from the engine for feeding the engine with supercharged scavenging air, at least one air cooler (2) located downstream of the trubocharger for reducing the temperature of the scavenging air, and at least one auxiliary blower (4) designed as centrifugal blower (4) for feeding the engine with additional scavenging air and scavenging air pressure when the load is reduced to a predetermined value during operation. The inlet of the at least one centrifugal blower (4) is connected to the outlet of the one centrifugal blower (4) is connected to the outlet of the at least one intercooler (2) whereas its outlet is connected to a scavenging air container (5) belonging to the engine. The turbocharge arrangement utilises the centrifugal blowers that already form part of the arrangement. Thereby, a simple and inexpensive structure is obtained that is able to effectively eliminate condensed water from the supercharged and cooled scavenging air which is fed to the diesel engine during operation.

Claims

AMENDED CLAIMS
[received by the International Bureau on 05 December 2002 (05.12.02) claims lf- 10 replaced by claims 1-9];
A turbocharge arrangement especially for a two-stroke diesel engine comprising at least one turbocharger (1) driven by the exhaust gasses from the engine for feeding the engine with supercharged scavenging air, at least one intercooler (2) located downstream of the at least one turbocharger (1) for reducing the temperature of the scavenging air, and at least one auxiliary blower (4) designed as a centrifugal blower (4) for feeding the engine with additional scavenging air and scavenging air pressure when the load is reduced to a predetermined valvue during operation, characterized in that the inlet (9) of the centrifiigal blower (4) is connected to the outlet of the at least one intercooler (2) whereby the own outlet (12) of the blower is connected to a scavenging air container (5) of the engine and whereby a drain chamber (24) having at least one inlet opening (32) for guiding condensed water separated from the cooled scavenging air flowing through the centrifiigal blower (4) into the drain chamber (24), and at least one outlet (34; 35) for guiding the caught condensed water out of the drain chamber are designed in the lower area of the blower housing (17) of the at least one centrifugal blower (4).
A turbocharge arrangement according to claim 1, characterized in that the fan wheel (18) of the at least one centrifugal blower (4) has a mainly horizontal axis of rotation.
A turbocharge arrangement according one of the preceding claims, characterized in that the at least one inlet opening (32) for guiding condensed water into the drain chamber (24) of the at least one centrifugal 14
blower comprises at least one mainly slit-formed aperture (32) pointing in the direction of dominant flow direction in the centrifugal blower (4).
4. A turbocharge arrangement according one of the preceding claims, characterized in that a perforated plate (25) is placed at a distance from the curved exterior wall (23) of the at least one centrifugal blower (4) along an area extending from the drain chamber (24) of this centrifugal blower (4) to or up against its outlet (12), said plate defining together with the exterior wall (23) a drain channel (27) opening into the drain chamber (24).
5. A turbocharge arrangement according to claim 4, characterized in that the drain channel (27) is designed with a least one flow resistance (28).
6. A turbocharge arrangement according to claim 5, characterized in that the flow resistance of the drain channel (27) consists of a mesh (28) inserted in the drain channel.
7. A turbocharge arrangement according one of the preceding claims 4, 5 or 6, characterized in that a partition (29) is inserted in the drain chamber (24) and is dividing the drain chamber (24) into a first section (30) having its at least one flow direction pointing in the direction of the slit-formed opening (32) and a second section (31) with the outlet of the drain channel (27) in the drain chamber (24) and that each of these two sections (30; 31) have at least one outlet (34; 35) for guiding the caught condensed water out of the respective section.
8. A turbocharge arrangement according to one of the preceding claims, characterized in that in the connection between the inlet (9) of the at least one centrifugal blower (4) and the outlet (12) of the at least one intercooler is inserted an individual water separator. 15
9. A turbocharge arrangement according one of the preceding claims, characterized in that the at least one centrifugal blower (4) is connected to an electric motor arranged to rotate the centrifugal blower at a predetermined reduction of the engine load and to be rotated by the centrifugal blower at a predetermined smaller reduction.
