摘要： An apparatus for treating fuel vapor, such as in a motor vehicle fuel tank, by subjecting it to adsorption treatment to prevent its direct emission into the atmosphere. The apparatus according to the present invention comprises a fuel tank, a partitioning wall provided within the fuel tank to define a small fuel storage chamber within the fuel tank, a canister container housed in the small fuel storage chamber, the canister container storing therein a fuel adsorbing material. When fuel feeding takes place, feeding fuel is introduced into the small fuel storage chamber to cool the canister container. However, when the engine is operated, high temperature return fuel is introduced into the small storage chamber to heat the canister container thereby promoting the adsorbing and de-adsorbing action of fuel by the fuel adsorbing material.

摘要： A fuel nature measuring device for measuring the nature of fuel stored in a fuel tank includes a measurement passage, a gas flow generator, a pressure detector, an concentration operator, a temperature detector, and a volatility calculator. The measurement passage has an orifice. The gas flow generator generates gas flow in the measurement passage. The pressure detector detects a differential pressure between opposite ends of the orifice. The concentration operator determines a concentration of evaporated fuel in the fuel tank based on the differential pressure detected when the opposite ends of the measurement passage communicate with the fuel tank and the fuel flows in the measurement passage. The temperature detector determines a temperature of the fuel in the fuel tank. The volatility calculator calculates a volatility of the fuel in the fuel tank based on the concentration of the evaporated fuel and the temperature of the fuel in the tank.

摘要： A fuel pump suctions fuel from a fuel tank and discharges it into a pressure tank. Then, the fuel pump suctions the fuel from the pressure tank and pressurizes it. Then, the fuel pump discharges the pressurized fuel toward an engine side through a fuel discharge pipeline. A pressure control valve is opened to communicate an inside of the fuel tank and an inside of the pressure tank when a pressure in the pressure tank becomes equal to or greater than a predetermined pressure. A canister receives activated carbons for absorbing vapor fuel from the fuel tank. A pressurizing pump suctions the vapor fuel from the canister and pressurizes it. The pressurized vapor fuel is then discharged from the pressurizing pump into the pressure tank, so that the vapor fuel is dissolved into the fuel in the pressure tank.

摘要： Operation of a fuel vapor control apparatus having a canister and a fuel vapor purging passage is detected occasionally by a pressure sensor which is disposed in a fuel tank of an engine. The sensor detects pressure changes in the purging passage caused by closing or opening the passage between the canister and a suction pipe of the engine, and by introducing or by interrupting the air flowing into the canister. A computer calculates signals generated by the sensor and decides whether or not any failure has occurred in the fuel vapor control apparatus. An air intake unit which has an air filter and an air switching valve is detachably installed close to the canister. When the air switching valve is controlled to introduce the air into the canister, the air passes the filter before the switching valve so that the valve may not be subject to dust or foreign particles contained in the air and good sealing of the valve is ensured for long time. As a result, highly reliable failure detection is attained, and the apparatus is easy to be installed in a vehicle.

Switching valves are disposed in the measurement passage to create a first concentration measurement state in which the measurement passage is opened at both ends thereof and the gas flowing through the measurement passage is the atmosphere, and a second concentration measurement state in which the measurement passage is in communication at both ends thereof with a canister and the gas flowing through the measurement passage is a fuel vapor-containing air-fuel mixture provided from the canister. An ECU calculates a fuel vapor concentration by based on a pressure difference detected in the first concentration measurement state and a pressure difference detected in the second concentration measurement state.

摘要： A fuel adsorption layer formed in a canister is partitioned into an upper adsorption layer and a lower adsorption layer by a partition plate in which a heater is embedded. The relation between a heating value of the heater and thickness X of the upper and lower adsorption layers is set so that the temperature of a part closest to the heater heating face of the fuel adsorption layer is lower than a fire point of the fuel, and the temperature of a part farthest from the heater heating face is higher than the boiling point of the fuel. With the configuration, by heating the fuel adsorption layer by the heater, the desorption performance of activated carbon is improved, and almost all of the fuel vapors adsorbed can be desorbed.

摘要： A fuel vapor purging system includes a container in which a set of divided chambers are formed by partition walls. Absorbent is disposed in the divided chambers. The divided chambers are sequentially connected to form a zigzag passage. Fuel vapor can enter the container from a fuel tank via a vapor line connecting the fuel tank and the container. In the container, an end of the vapor line faces the divided chamber which occupies an end of the set of the divided chambers. In the container, the fuel vapor is absorbed by the absorbent. Air can escape from the container via an opening in the container. The fuel vapor can be separated from the absorbent. The separated fuel vapor can be drawn into a suitable drawing device such as an engine air induction device via a purge line connecting the container and the drawing device. Fresh air can flow into the container via an air inlet provided on the container. Among the divided chambers, at least the divided chamber which occupies the end of the set of the divided chambers has a cross-sectional area equal to or smaller than 40 cm.sup.2.

摘要： A concentration-detecting unit detects concentration of fuel vapor flowing in a concentration-detecting passage branched from a purge passage. The concentration-detecting passage communicates with a communicating passage of a canister. Air including the fuel vapor of which concentration is detected by a concentration-detecting unit is returned to the communicating passage of the canister. The fuel vapor is adsorbed by an absorbent accommodated in a accommodating chamber to restrict a discharge of the fuel vapor into atmosphere.
