摘要： A gaseous fuel-air mixer includes an outer shell, an inner shell, and a fuel chamber rib. The outer shell includes an air intake and a fuel intake. The air intake is configured to receive air. The air intake has an air outlet. The fuel intake has a fuel inlet that is configured to receive fuel. The inner shell includes an inner shell intake that is configured to separately receive the air from the air outlet and the fuel from the fuel intake and to provide a gaseous fuel-air mixture. The inner shell cooperates with the outer shell to define a fuel intake collecting chamber that is configured to receive the fuel from the fuel inlet and a fuel intake concentrating chamber that is configured to receive the fuel from the fuel intake collecting chamber and provide the fuel to the inner shell intake.

摘要： A combustion system for an internal combustion engine includes a cylinder wall; a cylinder head disposed at an end of the cylinder wall, an internal surface of the cylinder wall and the cylinder head defining a combustion chamber; a fuel injector having a discharge nozzle disposed within the combustion chamber and configured to discharge a fuel jet along a fuel jet axis; and a bluff body disposed within the combustion chamber, the fuel jet axis intersecting an exterior surface of the bluff body. The exterior surface defines a first aperture and a second aperture therethrough, and an interior surface of the bluff body defines a first flow passage extending from the first aperture to the second aperture. The first aperture faces away from the fuel jet axis and the second aperture faces away from the fuel injector along the fuel jet axis.

摘要： Disclosed in this description are modifications either attached to, or made as part of, accelerator pump discharge nozzles, tubes or pipes. These modifications include the use of a fuel atomizer plate for carburetors as either a separate device placed beneath or on top of an accelerator pump discharge nozzle, tube or pipe, or simply located in the fuel stream of an accelerator pump discharge nozzle, tube or pipe, or a fuel atomizer plate for carburetors made as a single unit along with an accelerator pump discharge nozzle, tube or pipe. All are used on standard engines and assist in the atomization and homogenization of incoming fuel with incoming air to improve engine performance

摘要： A two stroke engine comprises a cylinder, in which a combustion chamber bounded by a piston is formed, and an intake passage. A carburetor forms a section of the intake passage, within which a throttle element is mounted pivotably, and at least one main fuel opening and at least one idling fuel opening open into the intake passage, which is divided downstream of the carburetor into an air passage and a mixture passage. The idling fuel opening feeds a secondary passage arranged within the mixture passage. In the idling position, the throttle element may be arranged adjacent to the upstream entry opening in the secondary passage, and the throttle element may have an opening which, in the idling position of the throttle element, is arranged in the region of the entry opening and connects the secondary passage to that region of the intake passage located upstream of the throttle element.

摘要： A system for removing unwanted contaminates from gases using a scrubber, which comprises a housing, a reaction chamber having a liquid level, an inlet connected to a source containing gases to be scrubbed with a contamination concentration greater than zero ppb to saturation. A gas exit port connected to the housing is used for evacuating scrubbed gas and a sintered permeable membrane is disposed across the reaction chamber, which provides a reaction zone in the plurality of pores when gases to be scrubbed are introduced to the membrane on a first side while the membrane is immersed in the lean liquid; and a cleaned gas on a second side wherein the clean gas initially has a drop in contamination concentration of at least 99 percent and gradually decreasing to 70 percent as additional gases to be scrubbed are introduced to the plurality of pores without replacing the lean liquid.

摘要： The present invention provides an air intake noise reducing device, an internal combustion engine fitted with the air intake noise reducing device and a structure for fitting the air intake noise reducing device to the internal combustion engine. The air intake noise reducing device comprises a gasket (2) comprising a ring member (2a) held by connecting surfaces of an air intake passage (100) and protrusion holding portions (2b) extending from the ring member (2a) toward a center of the air intake passage (100); and a net member (3) comprising a net (3a) for rectifying intake air and connecting protrusions (3b) extending outward from the net (3). The connecting protrusions (3b) are held in the protruding holding portions (2b) such that the ring member (3) is firmly secured to the gasket (3). The air intake noise reducing device constituted by in the above-mentioned manner can reduce assembly man-hours without deteriorating a sealing property of the air passage.

摘要： A flame protection gasket has a gasket member with an embedded screen member within its structure. The screen member and gasket member are disposed in a common plane. The screen member is attachable to an air conduit structure in a manner that inhibits its removal after the attachment is completed. In addition, since the gasket member and screen member are part of an integral structure, the screen member must be replaced if the gasket member is replaced following repair or reassembly.
