摘要： A fuel vapor treatment system includes a canister containing an adsorbent, a detector detecting a concentration of a fuel vapor, a purge passage for introducing the mixture gas into an engine, and an ECU which controls a purge based on a detected fuel vapor condition quantity and learns a fuel vapor concentration. If a difference between a learned concentration and a detection concentration is not less than a specified value, the ECU performs a purge control based on the learned concentration prior to a purge control based on the detection concentration.

摘要： A fuel vapor treatment apparatus includes a first canister purges fuel vapor into an intake passage of an engine through a purge passage, which communicates with a first detection passage having a throttle. A second canister is located on an opposite side of the purge passage with respect to the throttle, and communicates with the first detection passage. A gas flow generating unit generates gas flow by reducing pressure in a second detection passage communicating with the second canister. A pressure detecting unit detects pressure correlated with the throttle and the gas flow generating unit. An exhaust detecting unit detects exhaust of fuel vapor from the second canister to the second detection passage. A purge control unit controls purge of fuel vapor from the purge passage to the intake passage in accordance with detection results of the pressure detecting unit and the exhaust detecting unit.

摘要： When a gas flow producer is driven, plural kinds of gases flow into a measure-passage at respective timing. An orifice is provided in the measure-passage. The orifice has a diameter-changing portion which restricts a separation of gases from an inner surface of the measure-passage. A pressure sensor is provided in the measure-passage to detect a pressure determined by the orifice and the gas flow producer. A microcomputer calculates a density ratio between the gases based on the detected differential pressure.

The sensor device also includes a beat oscillator having plural oscillators of different oscillating frequencies. The beat oscillator generates a beat signal of a frequency lower than the oscillating frequencies. The beat signal corresponds to a difference of the oscillating frequencies. The beat oscillator is electrically connected to the sensor such that the frequency of the beat signal changes in accordance with the changes in the resistance value of the sensor.
