In a compressor for a supercharger of an internal combustion engine comprising a shroud (4), an impeller (10), a vaneless diffuser (20), and a scroll (30), a hub-side wall (22) of the vaneless diffuser (20) is formed to be inclined to the opposite side to a shroud-side wall (24) with respect to a…
An object of the invention is to provide a scroll structure of a turbine housing of a twin scroll turbocharger of which flow-through abilities of two exhaust gas passages are equal to each other. A tongue (44), which partitions a scroll portion (26) into an outer peripheral portion (26a) and an…
To provide a turbocharger capable of turbocharging efficiency and reducing cost by suppressing a rapid expansion of exhaust gas blown from an outlet of a scroll in the vicinity of an inlet of a rotor blade, a twin-scroll turbocharger (1) comprises a rear scroll (22), a front scroll (21), a scroll…
The present invention relates to a dual-volume volute (10) for a gas turbine (50) comprising a circumferential spiral-shaped conduit (11), a first opening (12) arranged tangentially to said circumferential conduit (11) towards the exterior of said circumferential conduit (11) and a second…
The turbocharger has a bearing housing (4) formed adjacent a turbine housing (3) and two largely mutually parallel flow channels (6,7) of exhaust gases. A spiral wall (8) comprises the bearing housing facing a flow channel (6) belonging to the wall (10). The radial distance between the bearing…
A statorless or nozzleless axial turbine for a turbocharger has an axial turbine wheel that receives a swirling flow of exhaust gas substantially in an axial direction. The turbine includes a sector-divided turbine housing defining a plurality of separate exhaust gas inlets each for receiving a…
In a turbine scroll part structure of a radial turbine, a flow passage 3 of a connecting part between an exhaust gas inlet into a turbine housing 5 and a scroll part 1 is offset along an axis line L1 of a rotating shaft of a turbine rotor in an amount H, and a cut-out portion P is formed in a…
The turbocharger (1) for an internal combustion engine, using the exhaust gas, has a housing containing a compressor (3) and an exhaust gas turbine (4) which forms a section of the exhaust pipe (5) from the engine (6). A feedback (7) runs from the exhaust system after the catalyst (9) which follows…
A turbocharger (2) mounted on an engine (1) has an EGR pipe (11) through which part of exhaust gas (8) is extracted from an exhaust manifold (9) to be recirculated to a suction pipe (4), the exhaust manifold (9) being internally divided by a partition (14) for prevention of exhaust interference…
The engine has a compressor impeller (50) for increasing pressure of a gas mixture to be combusted in the engine. A duct (28) supplies the gas mixture to the compressor impeller. Another duct (30) supplies additional gas mixture into the duct (28) at a connection upstream of the compressor…
The exhaust gas manifold (1) has a flange plate (6) directly attached to the engine block (5) of the IC engine, provided with an opening (7) for each of the engine cylinders and a sheet steel manifold housing (11), providing gas channels (12-15) leading from the openings to an exhaust gas turbine…
An engine turbocharger includes a turbine inlet scroll (38) for conducting exhaust gas from a laterally offset position to the annular inlet of a turbine wheel (18). An outer wall (54) defines a generally S-shaped passage connecting an inlet flange with concentric annular outlet flanges aligned on…
Exhaust gas turbocharger comprises an exhaust gas turbine (3), a turbine housing (1), in which a spiral-wound inlet channel (2) beginning with an inlet connection (5) is molded to receive an exhaust gas stream guided to the exhaust gas turbine, and devices for leading the exhaust gas stream in the…
