20100236513 | AIR INTAKE SYSTEM FOR INTERNAL COMBUSTION ENGINE - An air intake system for internal combustion engine includes an intake manifold having an inlet flange and a throttle body attached to inlet flange. The throttle body includes a matching throttle body flange which physically mates with the intake flange. A friction promoting surface having a positive coefficient of sliding friction is incorporated in at least one of the inlet flange and the throttle body flange so that sliding motion of the throttle body relative to the intake manifold will be resisted. | 09-23-2010 |
20100313421 | METHOD FOR MOLDING PRODUCTS ADAPTED FOR USE IN DIFFERENT APPLICATIONS - A method is provided for forming intake manifolds for an internal combustion engine and for fastening such manifolds to the engines. The method includes: molding a plurality of identical ones of the intake manifolds, each one of the intake manifolds being molded with at least one hollow projection extending outwardly from an outer surface of the manifold, each one of the projections being molded with a cap at the distal end to seal the distal end of the hollow projection; removing the cap at a selected one or ones of the projections while leaving the cap on unselected one or ones of the projections; fastening each one of the intake manifolds to a corresponding one of a plurality of internal combustion engines; and for each one of the fastened intake manifolds, attaching a hose or hoses to the distal end or ends of the selected one or ones of the plurality of projections. | 12-16-2010 |
20100326395 | Cover with Integrated Braces - A composite material intake manifold cover includes braces integral to the outside surface of the cover to stiffen the cover and reduce noise and vibration associated with the cover. The cover has a flange around the periphery with a raised weld bead, the weld bead provided for welding the cover to a mating piece. The flange extends outwardly from the cover for a first distance over most of the periphery and a second distance to support the braces over the remainder of the periphery. The braces extend upwardly from the upper surface of the flange at the sections of the flange extending out the second distance and may be placed between adjacent intake runner ports. By providing portions of the flange extending out a greater distance, a more substantial brace can be supported, thereby improving the noise and vibration characteristics relative to conventional stiffening ribs. | 12-30-2010 |
20110259293 | Intake Manifold - An intake manifold assembly has one or more shells coupled together and coupled to a cover. When the manifold cover, or other exterior surface, is rounded, the manifold does not sit stably on a flat surface when the rounded is placed onto the flat surface. The manifold may roll off a table and be damaged. To mitigate such situation, the rounded surface is provided with at least two standoffs extending outwardly from a surface of the cover with distal ends of the standoffs substantially lying in a common plane. The standoffs have a central axis and the standoffs extend outwardly from the surface along the central axis at least as far as any other feature of the intake manifold assembly. | 10-27-2011 |
20110315125 | VACUUM PORT HAVING A FLOW DISRUPTOR - An intake system is provided. The intake system including an intake manifold coupled to an engine and a vacuum port located in said intake manifold and in an air flow path downstream of a throttle body and upstream of said plurality of intake runners, the vacuum port including a molded flow disruptor including a cross-beam traversing an outlet of the vacuum port. The intake system may further include a vacuum passage coupling the vacuum port to a vehicle subsystem. | 12-29-2011 |
20110315131 | Vacuum Port Having a Flow Disruptor - An intake system of an engine is provided. The intake system including an intake manifold, a vacuum port located in said intake manifold and in an air-flow path downstream of a throttle body and upstream of a plurality of intake runners, the vacuum port including a molded flow disruptor including a cross-beam traversing an outlet of the vacuum port, the cross-beam oriented at an angle between 0 and 90 degrees with respect to an axis of a throat in the intake manifold, and a vacuum passage coupling the vacuum port to a vehicle subsystem. | 12-29-2011 |
20120012078 | INTAKE MANIFOLD FOR INTERNAL COMBUSTION ENGINE - An intake manifold for an internal combustion engine having a housing having a uniformly thick, outwardly facing arch shaped elongated arm for mounting to a cylinder head of the internal combustion engine with an outer surface of the arm having an outwardly facing projection disposed along a portion of a length of the elongated arm. The projection is integrally formed with the arm. The projection is at, or proximate to, the apex of the arch of the arch shaped arm. | 01-19-2012 |
20130112159 | PCV SYSTEM HAVING INTERNAL ROUTING - A positive crankcase ventilation (PCV) system is provided herein. The PCV system includes an engine assembly, the engine assembly including an engine block, a cylinder head, a valve cover, and an intake manifold and a PCV passage providing fluidic communication between a crankcase of the engine assembly and a cylinder intake port of the engine assembly without hoses or conduits external to the engine assembly. | 05-09-2013 |
20130186364 | CYLINDER HEAD ASSEMBLY HAVING A DRAINAGE PASSAGE - A cylinder head assembly is provided. In one example, the cylinder head assembly includes a cylinder head, a cam cap coupled to the cylinder head having a component port, and a cam cover coupled to the cylinder head. The cylinder head assembly cylinder head assembly further includes a drainage passage including an inlet opening and an outlet extending through an exterior cylinder head surface. | 07-25-2013 |
20140041640 | VACUUM PORT HAVING A FLOW DISRUPTOR - An intake system is provided. The intake system including an intake manifold coupled to an engine and a vacuum port located in said intake manifold and in an air flow path downstream of a throttle body, the vacuum port including a molded flow disruptor including a cross-beam traversing an outlet of the vacuum port. The intake system may further include a vacuum passage coupling the vacuum port to a vehicle subsystem. | 02-13-2014 |
20140047700 | Composite Engine Part and Fastener Assembly and Method of Securing a Composite Part to an Engine - A method of securing a composite plastic part to an engine with a bolt or a bolt and washer. The bolt has a head including teeth that are adapted to engage either the part or the washer. The bolt is tightened to cause the teeth to compress the surface of the part to resist rotation that may become loosened as a result of vibration of the engine. The part may be an intake manifold, a cam cover or an oil pan. Locking features, such as teeth, may be provided on the clamping surface of the bolt and on both surfaces of the washer. Alternatively, a knurled or serrated surface may be provided instead of the teeth. | 02-20-2014 |
