摘要： The intake structure for an internal combustion engine includes: a collision surface configured to face an inlet of a carburetor; a deflecting surface configured to deflect a blowback flow, which is to diffuse after colliding against the collision surface, in one direction along the collision surface; a receiving surface configured to receive the blowback flow deflected by the deflecting surface; and a fuel-accumulating surface formed below the collision surface. A first clearance between an air-guiding direction distal end of the deflecting surface and the receiving surface is brought into communication to a downstream side of a filter of an air cleaner in a fresh-air intake direction so as to act as a main intake passage for fresh air.

摘要： Methods and systems are provided for computing the flow rate at a suction port of an ejector arranged in series with an outlet of an engine system such as a fuel vapor purge system during certain conditions. In one example, the need for a sensor at an ejector suction port may be reduced by adjusting exhaust gas recirculation based on a flow rate at the ejector suction port, the flow rate based on a flow characteristic of the ejector and a flow characteristic of an engine system. The flow rate and a reductant concentration of gases from the engine system may then be used as a basis for compensation of a diluent concentration measurement taken by a gas constituent sensor arranged downstream of the ejector outlet in an engine intake passage, e.g. to improve adjustment of exhaust gas recirculation based on the compensated diluent concentration measurement.

摘要： A fuel vapor processor has a fuel tank configured to reserve fuel, a canister containing adsorbent capable of adsorbing fuel vapor vaporized in the fuel tank, a separator receiving a fuel vapor containing gas from the fuel tank, a regulator controlling the volume of the fuel vapor containing gas supplied to the separator, and a suction unit capable of removing the fuel vapor from the canister. The separator selectively passes the fuel vapor therethrough in order to divide the fuel vapor containing gas into a first gas mainly containing the fuel vapor and a second gas having a fuel vapor density lower than the first gas. The suction unit suctions the first gas from the separator in order to return the first gas into the fuel tank. The second gas is introduced into the canister or is released into the atmosphere.

摘要： A retention assembly secures a hydrocarbon trap within an air intake path of an internal combustion engine. The hydrocarbon trap is positioned within a first air tube, such as an outlet duct of a clean air filter. A second air tube, such as an inlet portion of a clean air duct assembly, is fitted over a portion of the first air tube to enclose the hydrocarbon trap within the first air tube. A clamp is fitted over both the first and second air tubes. A plurality of radially-extending, circumferentially-spaced protrusions that are formed on an inner surface of the second air tube pass through a respective plurality of apertures formed in the first air tube and, under radial compression exerted by the clamp, engage an outer surface of the hydrocarbon trap, thereby securing the trap within the first air tube.

摘要： An air bleed vapor system is provided having a primary vapor manifold connected to a fuel line take-off for providing a source of liquid fuel to the system. A vapor control module incorporates a precision needle valve for allowing metering of extremely small flowrates of liquid fuel into the vapor manifold. A pressure line is inserted into the PCV intake of a vehicle, and a secondary vaporization chamber is in fluid communication with the pressure line and the vapor control module, and provides an oxygen intake chamber into which an air-fuel mixture can be held at the pressure of the vehicle's crankcase ventilation system. Finally, a delivery vaporization conduit in the form of a linearly elongated chamber is in fluid communication with the PCV manifold of the vehicle.
