Patent number: 6715738Abstract: A fuel-air mixture control apparatus for adjusting the mixture of fuel and air that a carburetor provides to an internal combustion engine. A mixing passage provides a fuel-air mixture to one or more combustion chambers of an internal combustion engine. A main fuel supply passage provides fluid communication between a fuel source and the mixing passage through a main fuel nozzle. An idle fuel supply passage provides fluid communication between a fuel source and the mixing passage through an idle fuel nozzle. An idle fuel ratio control valve adjusts the proportion of fuel drawn into the mixing passage through the idle fuel supply passage to the flow rate of air drawn into the mixing passage. The idle fuel supply passage is in fluid communication with the main fuel nozzle. Vacuum pressure induced by flow rates across the main fuel nozzle, which exceed a predetermined flow rate, precludes idle fuel flow into the mixing passage.Type: GrantFiled: September 25, 2002Date of Patent: April 6, 2004Assignee: Walbro Engine Management LLCInventors: Matthew A. Braun, Masatoshi Endo, David L. Speirs

Patent number: 6688585Abstract: A carburetor for a scavenged two-stroke internal combustion engine has an enriched fuel-and-air mixing passage extending through a housing of the carburetor. Engaged to the housing is a body of an air flow modular assembly which carries a primary air flow passage which houses a butterfly-type control valve therein. The throttle valve of the fuel-and-air mixing passage is mechanically linked or cammed to the control valve of the air flow passage so that opening of the throttle valve soon after opens the control valve allowing additional air to enter and provide a leaner fuel-and-air ratio in the combustion chamber of the engine when running under load. The air flow modular assembly has a sealing-and-bearing assembly which eliminates air leakage from the surrounding environment along the shaft of the control valve and into the primary air flow passage. The sealing-and-bearing assembly has a bushing which inserts into a counter bore of a cylindrical bore which receives the rotating shaft of the control valve.Type: GrantFiled: May 28, 2002Date of Patent: February 10, 2004Assignee: Walbro Engine Management LLCInventors: Matthew A.
