Patent application number | Description | Published |
20110253080 | Intake Manifold with Overmolded Structural Enhancement - A composite intake manifold coupled to a V-engine is provided. The composite intake manifold includes a supporting member overmolded in an unsupported region of the composite intake manifold. | 10-20-2011 |
20120017864 | Intake Manifold Metal Posts - An intake manifold is disclosed which has an upper shell portion having a first peripheral flange, a lower shell portion having a second peripheral flange, and at least one metallic post having a first plate and a second plate. The first and second peripheral flanges are friction welded and the first plate of the posts is friction welded to the upper shell portion and the second plate of the posts is friction welded to the lower shell portion. The upper and lower shells are made of a polymeric, or plastic, material. The metallic post is comprised substantially of aluminum or other suitable metals or alloys. The upper and lower shell portions define a cavity and a section of the post between the first and second plates traverses through the cavity. | 01-26-2012 |
20130139777 | Intake Manifold with Overmolded Structural Enhancement - A composite intake manifold coupled to a V-engine is provided. The composite intake manifold includes a supporting member overmolded in an unsupported region of the composite intake manifold. | 06-06-2013 |
20140130754 | VARIABLE CAM TIMING SYSTEM AND METHOD - A phase control apparatus in a variable cam timing (VCT) system of an engine is described herein. The phase control apparatus includes a locking pin coupled to a vane, the locking pin extending into a locking pin recess in a cover plate in a locked configuration, the locking pin and locking pin recess having a backlash and a housing at least partially enclosing the vane and spaced away from the vane forming a gap in the locked configuration. | 05-15-2014 |
20140165951 | STRUCTURE TO REDUCE NOISE AND VIBRATION IN AN ENGINE SYSTEM - Adding dome-shaped protuberances, or polydomes, to an engine system increases the structural integrity of the engine component to which they are added and allows noise radiated in the engine system to be reduced in certain regions of the frequency spectrum without incurring a significant increase in the mass of the engine part to which they are added, which may result in a longer solidification time during the mold injection process. The size and spatial arrangement of polydomes relative to one another can be further adjusted to reduce noise within the engine system and polydomes may be reinforced with ribs to increase the structural stiffness of plastic engine components. Because plastic engine components are created using an injection mold process during the manufacturing process, added surface features (e.g. polydomes and ribs) are continuous with the underlying planar surface to which they are added. | 06-19-2014 |
20140241928 | VACUUM PUMP WITH ROTOR-STATOR POSITIONING TO PROVIDE NON-RETURN - A rotary-vane vacuum pump comprises a stator and a vaned rotor, the stator partly defining an outlet chamber and including an outlet passage opening to the outlet chamber. The rotor is rotatably sealed to the stator; it has a sealing area to block the outlet passage, and, an unsealing area alignable with the outlet passage by rotation of the rotor to periodically unblock the outlet passage. The disclosed pump offers reduced resistance to lubricant oil discharge from the outlet passage, which results in lower differential pressure between inlet and outlet chambers at the end of the pumping cycle. | 08-28-2014 |
20140322061 | CHECK VALVE FOR AN ENGINE VACUUM PUMP - A rotary vane pump includes a housing that encloses an air chamber. An intake aperture extends to the air chamber. A check valve couples with the intake aperture and includes a stop having first and second sides. A helical spring engages the first side and biases the second side against a valve seat. A porous body is disposed between the helical spring and the air chamber for preventing fluid backflow. | 10-30-2014 |
20140338308 | EXHAUST SYSTEM HAVING A FLOW ROTATION ELEMENT AND METHOD FOR OPERATION OF AN EXHAUST SYSTEM - An exhaust system in an engine is provided. The exhaust system includes an exhaust manifold include at least one exhaust runner having an inlet and a flow rotation element including at least one vane, the flow rotation element positioned in the inlet of the exhaust runner swirling exhaust airflow entering the exhaust runner. | 11-20-2014 |
20140338309 | EXHAUST SYSTEM HAVING A FLOW ROTATION ELEMENT AND METHOD FOR OPERATION OF AN EXHAUST SYSTEM - An exhaust system in an engine is provided. The exhaust system includes an exhaust passage including an outlet, in fluidic communication with at least one combustion chamber in the engine, and integrated into a cylinder head in the engine and a flow rotation element including at least one vane, the flow rotation element positioned in the outlet of the exhaust passage swirling exhaust airflow exiting the exhaust passage. | 11-20-2014 |
