| 20130022445 | System for Reducing Compressor Oil Consumption - An air induction system for a power source including a first compressor and a second compressor is disclosed. The air induction system includes an air feed passageway that directs compressed air from the second compressor to an area between a compressor wheel and a center housing in the first compressor to reduce oil consumption in the first compressor. | 01-24-2013 |
| 20120152214 | TURBOCHARGER SYSTEM - This disclosure is directed to a turbocharger arrangement having a high pressure turbocharger and a low pressure turbocharger connected in series. The low pressure turbine has first and second volutes and the arrangement includes a control valve which controls the proportion of exhaust gas which is directed through the first and second passages to the first and second volutes. | 06-21-2012 |
| 20120090581 | EXHAUST GAS MIXING SYSTEM - In one aspect a mixing tube is provided for the introduction of a flow of exhaust gas into a flow of intake air of an internal combustion engine. The mixing tube comprises an opening, tube section, and a plurality of tube ports. The opening is configured to receive the flow of exhaust gas. The tube section is fluidly connected to the opening and extends into the flow of intake air. The tube ports on the tube section are located in low static pressure regions that are determined as intake air passes around the tube section. | 04-19-2012 |
| 20120024268 | Exhaust Gas Recirculation (EGR) Apparatus - An Exhaust Gas Recirculation (EGR) apparatus for recirculating engine exhaust gas comprising a valve member disposed in an exhaust gas recirculation passage of an engine, the valve member movable between an open position and a closed position to control the flow of the exhaust gas through the exhaust gas recirculation passage, one or more bleeders to enable flow of exhaust gas through the exhaust gas recirculation passage when the valve member is in the closed position. | 02-02-2012 |
| 20110283886 | Method And Apparatus For Regenerating A Filter - The present disclosure refers to a method for regenerating a filter adapted to remove particulate material from a gas. The disclosed method comprises at least producing at least one electric arc discharge pulse, the at least one electric arc discharge pulse being adapted to generate at least one pressure wave so that the particulate material is being dislodged from the filter. In addition, the disclosure refers to a filter regenerating arrangement and a diesel particulate filter. | 11-24-2011 |
| 20110220051 | Push Rod Retainer, Rocker Arm and Method for Retaining Together a Push Rod and a Rocker Arm - Disclosed is a push rod retainer for retaining an extremity of a push rod and a first end of a rocker arm in proximity of each other, comprising a base section accommodating at least a part of a junction space wherein the extremity of the push rod and a connection member of the rocker arm are joinable; and at least two resilient projections extending from the base section and at least partly in a direction towards each other, said resilient projections bounding a first entrance to the junction space. Also disclosed is a rocker arm having a connection member that is provided with a circumferential constriction configured for engagement by the resilient projections of the disclosed push rod retainer, and a method of retaining together a push rod and a rocker arm. | 09-15-2011 |
| 20100326235 | METAL FORGED CRANKSHAFT, APPARATUS FOR METAL FORGING A CRANKSHAFT AND METHOD OF METAL FORGING A CRANKSHAFT - An apparatus ( | 12-30-2010 |
| 20100294216 | WATER PUMP HAVING A RESERVOIR - A water pump may be provided with a pump housing and a reservoir. The reservoir may have a first portion integral with the pump housing and a second portion manufactured as a separate part. The second portion has an internal volume which is in fluid communication with the first portion. A method is disclosed in which a fluid is drawn into a pump housing and pressurized. Some of the fluid is forced past a seal and collected in a part of a reservoir coupled to the pump housing. That reservoir part is heated to evaporate the fluid. | 11-25-2010 |
