| 123184460 | For use with carburetor upstream of manifold | 7 |
| 20080302326 | In-line induction system for internal combustion engine - In line carburetor ( | 12-11-2008 |
| 20090217899 | INTAKE MANIFOLD FOR INTERNAL COMBUSTION ENGINES - An intake manifold for an internal combustion engine that distributes a fuel-air mixture to an engine. The manifold includes a box-shaped chamber defined by at least four sidewalls. The chamber is mounted atop multiple intake runners, and opens to an intake plenum to which multiple runners are joined. The box-shaped chamber can include a mounting flange to which a substantially planar cover plate can be mounted to close the top of the box-shaped chamber. The cover plate can define at least one hole to accommodate a carburetor, throttle body or other fuel-air mixture delivery device. | 09-03-2009 |
| 20130220260 | Air Supply Apparatus for Two-Stroke Combustion Engine - The present invention relates to an air supply apparatus for a two-stroke stratified scavenging combustion engine. The air supply apparatus includes an air cleaner having an air outlet and a partition, such that the partition substantially divides the air outlet into a first section and a second section. The air supply apparatus further includes a carburetor. The carburetor includes a passage, a throttle valve and a choke valve, such that the throttle valve and the choke valve substantially divides the passage into an air portion and a mixture portion. Further, a first aperture in communication with the first section of the air outlet is provided corresponding to the air portion, and the second aperture in communication with the second section of the air outlet is provided corresponding to the mixture portion. Moreover, an area of the first section is different from that of the second section. | 08-29-2013 |
| 20140076258 | SADDLE-RIDE TYPE VEHICLE - A saddle-ride type vehicle is capable of reducing influence of travelling wind on an open end of an air hose, thus preventing fluctuations in the internal pressure of a float chamber of a carburetor. The saddle-ride type vehicle includes a carburetor placed rearward of an engine and an air cleaner placed rearward of the carburetor. An air hose configured to regulate the internal pressure of a float chamber of the carburetor is connected to the carburetor. A recessed portion is provided at a side wall of an air-cleaner case of the air cleaner, the side wall being located along a lateral side of the vehicle. An open end of the air hose is placed at the recessed portion of the air-cleaner case. | 03-20-2014 |
| 20140116372 | GASKET, THROTTLE BODY - A gasket which is mounted in a groove formed in a first member and is elastic and which seals between the first member and a second member, including: a first contact section that comes in contact with the second member; a second contact member that comes in contact with one sidewall surface of the groove which is formed in such a way that a width of the groove becomes larger toward an opening section of the groove from a bottom of the groove; a third contact section that comes in contact with another sidewall surface of the groove which is formed in such a way that a width of the groove becomes larger toward the opening section from the bottom; and a fourth contact section that comes in contact with the bottom. | 05-01-2014 |
| 20140165949 | Airflow Attachment Assembly for Carburetor - A carburetor attachment assembly for improved engine performance including an airflow crown and a mating air cleaner base. The air flow crown is adapted to detachably mount atop a carburetor and has a contoured intake surface that guides and directs airflow into the mouth of the carburetor. The airflow crown's intake surface is configured to merge with the sidewalls of the induction bores to form a smooth continuous surface around the mouth of the carburetor and induction bores, which helps facilitate laminar airflow and redirection of the intake air flow downward into the carburetor. | 06-19-2014 |
| 20150136058 | Carburetor air intake housing and air flow enhancing securement plate - An air intake housing and flow enhancing plate for a carburetor with a fluted and contoured air intake opening that flushly aligns with and matches the shape of the carburetor air intake opening. The low profile plate is made of metal for durability and heat resistance. The centrally located air intake opening of the plate has a clover leaf or undulating shape that conforms to the shape of the carburetor air intake opening. The plate is secured directly over the top of the carburetor, and extends radially outward to provide a larger area for securing its fiberglass housing. The housing holds a conventional ring shaped air filter located around the carburetor air intake opening. The plate provides smooth transitions between surfaces to decrease turbulence and improve air flow. | 05-21-2015 |
