An air spoiler apparatus with solar cells includes an air spoiler wing mounted on an outer surface of a vehicle body, solar cells mounted on an upper surface of the air spoiler wing, a running detector for detecting a running state of a vehicle, and an elevation angle adjustment unit of the air spoiler wing. The air spoiler elevation angle adjustment unit adjusts an elevation angle of the air spoiler wing within select angular ranges to increase power generation efficiency of the solar cells during parking, stopping, low-speed or high speed running represented by the running state detected by the running detector. During high speed operation the angular range is restricted to an optimum range for aerodynamic efficiency.

Air spoiler apparatus with solar cells for vehicle

A canister to be used in the fuel supplying system of an internal combustion engine of a vehicle, is disclosed. The canister is provided with a fuel vapors guiding pipe for guiding the fuel vapors from a fuel vapors inlet port into a bed of adsorbent material accomodated within a housing, and a deflector for deflecting the flow of fuel vapors guided by the guiding pipe so as to be dispersed throughout the bed. The deflector is formed of air-permeable material having a flowing resistance slightly larger than that of the bed into a frusto-conical plate. According to the present invention, one part of the fuel vapors flowing into the bed through the guiding pipe in the fuel vapors adsorbing process flows along the upper surface of the deflector in the direction of the upper portion of the bed and another part of the fuel vapors flows through the deflector in the direction of the lower portion of the bed. Fresh air sucked into the bed in the fuel vapors purging process flows through the bed without being obstructed by the deflector so that the fuel vapors adsorbed by the whole bed are purged.

Canister for internal combustion engine

A fuel evaporative emission control apparatus comprising a vessel having an adsorbent layer therein for adsorbing a vaporized fuel, and a vaporized fuel inlet conduit inserted in the adsorbent layer, wherein the improvement comprises a flow deflector of a hollow conical shape having a diameter gradually increasing upward, the deflector being embedded in the adsorbent layer, the vertical angle (.alpha.) of the flow deflector is adjusted to 60.degree. to 120.degree., the ratio (S1/S2) of the sectional area (S1) of the largest-diameter end portion of the flow deflector to the sectional area (S2) of the adsorbent layer is adjusted to 0.4 to 0.6, the ratio (a/b) of the distance (a) between the largest-diameter end portion of the flow deflector and the top end of the adsorbent layer to the distance (b) between the largest-diameter end portion of the flow deflector and the side end of the adsorbent layer is adjusted to at least 1.5, and the distance (a) is made smaller than the sum (g+b) of said distance (b) and the axial length (g) of the conduit in the adsorbent layer.

Fuel evaporative emission control apparatus for vehicles

An apparatus for adsorbing fuel vapor having a fuel vapor inlet communicating to a fuel tank, a mixed gas outlet communicating to the intake passage of an internal combustion engine, a desorbent air inlet communicating to the atmospheric air and an adsorbent for adsorbing the fuel vapor introduced from the fuel tank. The adsorbent includes an integrally formed activated carbon having a monolithic honeycomb structure having many through passages.

Apparatus for adsorbing fuel vapor

An apparatus for adsorbing fuel vapor having a fuel vapor inlet hole communicating to a fuel tank, a mixed gas outlet hole communicating to the intake passage for internal combustion engine, an inlet hole for the desorbent air communicating to the atmospheric air and an adsorbent for adsorbing fuel vapor and by using, as to the adsorbent which is at least partially foamed body of active charcoal constituting a three-dimensional network cell structure having an inner communicating space between granular active charcoals.

In a canister for a fuel evaporative emission control system of an automotive vehicle, a deflector of the conical frustum shape is embedded in the adsorbent layer of the canister. A diameter of the deflector gradually increases upwardly and a bottom of the deflector faces to the end of the inlet conduit. Dimensional relations of various parts of the deflector are specified. The deflector may include a check valve mounted on the underside of the bottom of the deflector.

Canister for fuel evaporative emission control system

A canister for a fuel evaporative emission control system of an engine; A mass of adsorbent contained in a canister casing is divided into at least two layers by a pair of spaced filter plates, so that the fuel vapors can be diffused into all parts of the adsorbent layers under the deflecting action of the filter plate and the uniforming action of a hollow space defined between the paired filter plates.
