摘要： A manually actuable primer for an internally vented float regulated fuel bowl type carburetor employs an arrangement for minimizing variations in fuel mixture richness resulting from variations in air intake path restrictions as might be created by a clogged air filter includes a bifurcated float bowl air vent conduit with one branch communicating with the carburetor bore in the region of the Venturi and the other branch communicating with the bore outside the region of the Venturi along with an arrangement for directing displaced fuel from the fuel supply chamber directly into a conduit which normally conveys fuel from a fuel well to the Venturi region, the directing arrangement being formed as an annular insert for the fuel well, the aperture of which forms the fixed fuel metering orifice of the carburetor. With this arrangement primer actuation pressurizes the region above the fuel in the float bowl, forcing fuel through the annular member directly into the nozzle communicating between the fuel well and the carburetor bore Venturi, while the bifurcated float bowl air vent arrangement allows a smaller vent opening into the float bowl, making float bowl pressurization priming feasible, while minimizing mixture richness changes normally associated with air intake obstructions such as a dirty air filter.
摘要翻译： 用于内部排气的浮动调节燃料碗型化油器的手动致动底漆采用了一种用于最小化由空气过滤器堵塞引起的进气通道限制的变化导致的燃料混合物浓度的变化的布置，其包括分叉的浮筒排气导管， 一个分支与文丘里管区域内的化油器孔相通，另一个分支与文丘里区域外的孔连通，另外一个分支与用于将来自燃料供应室的排出的燃料直接引导到通常从 燃料井到文丘里地区，导向装置形成为用于燃料井的环形插入件，其孔的孔形成化油器的固定燃料计量孔。 通过这种布置，底漆操作使浮筒中的燃料上方的区域加压，迫使燃料通过环形构件直接进入燃料井和化油器孔文丘里管之间连通的喷嘴，而分叉的浮筒排气装置允许较小的通风口 进入浮筒，使浮筒加压灌注成为可能，同时最大限度地减少与空气过滤器等进气障碍物通常相关的混合物丰富度变化。

摘要： Methods of operating fuel injectors with intensified fuel storage. At least one storage volume is provided in the intensifier type fuel injector, with a check valve between the intensifier and the needle chamber and storage volume preventing loss of injection pressure while the intensifier plunger cylinder is refilling with fuel. Using the check valve to isolate the storage volume from the intensifier to reduce and control pressure spikes that effect injector operation. This provides very efficient injector operation, particularly at low engine loads, by eliminating the wasted energy of compressing, venting and recompressing fuel for injection and reducing and controlling pressure spikes that effect injector operation.

摘要： In at least some implementations a carburetor may include a main bore through which a fuel and air mixture is delivered from the carburetor, a fuel metering assembly, a supplemental fuel pump and a valve. The supplemental fuel pump includes a diaphragm that defines a fuel chamber on one side from which fuel may be discharged to at least temporarily increase the amount of fuel discharged from the carburetor and a reference chamber on the other side that is communicated with a reference pressure source. The valve is electrically actuated and moveable between first and second positions to at least substantially prevent communication of the reference pressure source with the supplemental fuel pump diaphragm when the valve is in its second position to thereby inhibit or prevent fuel being discharged from the fuel chamber.

摘要： A purge and prime assembly for a carburetor includes a purge and prime pump that alternately takes in and discharges fluid, and a plurality of passages through which fluid is routed. The passages may include a purge passage through which fluid is drawn by the purge and prime pump, a return passage through which fluid is discharged from the purge and prime pump and discharged from the carburetor, and a priming passage through which a portion of the fluid discharged from the purge and prime pump is routed to a main bore of the carburetor. The assembly may also include a purge valve that prevents fluid from being discharged from the purge prime pump through the purge passage, and a return valve that prevents fluid in the return passage from being drawn into the purge and prime pump.
