Patent number: 7617679Abstract: An arrangement for recirculation of exhaust gases of a supercharged combustion engine. A return line which connects an engine exhaust line to an air inlet line for air supply to the combustion engine, to recirculate exhaust gases via the return line. A first EGR cooler in which the recirculating exhaust gases in the return line are cooled, as a first step, by a first coolant in a first cooling system. A second EGR cooler in which the recirculating exhaust gases in the return line are cooled, as a second step, by a second coolant in a second cooling system, and the second coolant is adapted to be at a temperature substantially corresponding to the temperature of the ambient surroundings when it is led into the second EGR cooler. A charge air cooler for the inlet line, a radiator for the second cooling system to cool the exhaust gases and a radiator element for cooling the second coolant.Type: GrantFiled: May 24, 2005Date of Patent: November 17, 2009Assignee: Scania CV AB (publ)Inventors: Zoltan Kardos, Pehr Söderberg, Erik Söderberg, Hans Wikstrom, Rickard Pettersson, Roland Ivarsson

Patent number: 7597088Abstract: A supercharger (10) is positioned in the valley of an automobile engine (60) so that it fits under the engine hood (25). The supercharger (10) has a low profile air inlet (14) at the top that passes air to an inlet tube (16). The height of the inlet tube (16) decreases and its width expands as the inlet tube (16) extends away from the air inlet (14) to keep a low profile while minimizing restrictions to airflow. The inlet tube (16) supplies air to a compressor (18) at the bottom. The pressurized air flows through a large and thin intercooler (24) directly above the compressor (18). The cooled air is fed to long and straight intake manifold runners (28) positioned above the engine heads (61, 62) of the engine (60). The supercharger (10) provides a large volume of low pressure and low temperature air charge to the engine (60).Type: GrantFiled: August 24, 2006Date of Patent: October 6, 2009Assignee: MJ Acquisitions, Inc.Inventor: William Tally

Publication number: 20090228192Abstract: The invention provides an intake-air cooling device for an internal combustion engine that can be installed compactly. The invention provides an intake-air cooling device for a gasoline engine equipped with an intercooler that cool intake air with outside air and an evaporator that cools intake air with refrigerant circulating in a bypass refrigeration circuit, disposed in this sequence in an intake-air channel from a supercharger to the gasoline engine. The intercooler is disposed in an outside-air duct through which outside air passes, the evaporator is disposed inside a case through which the intake air passes, and a bottom plate of the case forms part of the outside-air duct.Type: ApplicationFiled: February 3, 2009Publication date: September 10, 2009Applicants: MITSUBISHI HEAVY INDUSTRIES, LTD,, MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Hideto Noyama, Tsuyoshi Hayashi, Atsushi Kodama

Publication number: 20090223493Abstract: A condensate extractor system for an internal combustion engine assembly with a charge air cooler system is provided. The condensate extractor system includes a hose member with a first end in direct fluid communication with the charge air cooler system, and a second end in direct fluid communication with the intake manifold of the engine air intake system. The hose member removes condensate from the charge air cooler system in a continuous manner in response to a pressure gradient created by the throttle body when the engine is in an on-state. The hose member defines an orifice configured to restrict the flow of air and condensate through the hose member. A filter is placed in direct fluid communication with the hose member, upstream from the orifice. The hose member is preferably characterized by a lack of fluid communication with a reservoir configured to collect condensate.Type: ApplicationFiled: March 7, 2008Publication date: September 10, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventor: Thomas Porter Rutherford
