Patent number: 10113555Abstract: A turbocharger unit for an internal combustion engine having at least one exhaust line for the evacuation of exhaust gases from the combustion chamber of the engine and at least one inlet line for the supply of air to the combustion chamber is provided. The turbocharger unit includes a turbine which interacts with a compressor in order to extract energy from the exhaust-gas flow of the engine and pressurize the inlet air of the engine. The compressor is of the radial type and is provided with an impeller having backswept blades in which the blade angle between an imaginary extension of the center line of the blade between root section and tip section in the direction of the outlet tangent and a line connecting the center axis of the impeller to the outer tip of the blade is at least about 40 degrees. The ratio between the inlet diameter of the impeller and its outlet diameter lies within the range 0.50-0.62.Type: GrantFiled: June 30, 2014Date of Patent: October 30, 2018Assignee: Volvo Lastvagnar ABInventor: Magnus Ising

Patent number: 9273641Abstract: A gas flow unit includes a gas flow inlet, a gas flow outlet and a gas flow chamber configured to convey a gas flow from the inlet to the outlet, wherein the gas flow inlet is configured to convey the gas flow in a first direction into the gas flow chamber and wherein the gas flow outlet is configured to convey the gas flow in a second direction from the gas flow chamber, wherein the second direction is angular in relation to the first direction, and wherein the gas flow inlet is an inlet into the gas flow chamber and the gas flow outlet is an outlet from the gas flow chamber. In the first gas flow direction, the gas flow chamber extends beyond a projection of an outer periphery of the gas flow outlet and defines a prolongation configured for conveying a first part of the gas flow such that it enters the gas flow outlet from a different direction than a second part of the gas flow entering the gas flow outlet without passing through the prolongation.Type: GrantFiled: August 31, 2012Date of Patent: March 1, 2016Assignee: Volvo Truck CorporationInventors: Magnus Ising, Nader Najjar

Patent number: 7574862Abstract: A turbocharger unit for a multicylinder internal combustion engine has at least two exhaust lines for the evacuation of exhaust gases from the combustion chamber of the engine and at least one inlet line for the supply of air to the combustion chamber. The turbocharger unit includes at least one turbine which cooperates with at least one compressor to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. The turbine is provided with a worm-shaped housing having at least two flow paths which are defined by guide tongues in the housing and which conduct mutually separate exhaust flows via stator blades to at least one turbine wheel. In order to maintain the kinetic energy in the separate exhaust flows, each respective guide tongue meets a stator blade extending toward the tongue.Type: GrantFiled: September 22, 2004Date of Patent: August 18, 2009Assignee: Volvo Lastvagnar ABInventors: Kent Giselmo, Per Andersson, Magnus Ising
