Patent number: 5259355Abstract: A fuel evaporative emission flow rate detecting system is capable of detecting a small flow rate of the fuel evaporative emission. The system includes an electromagnetic valve (22) in a communication passage (21). The pressure of the fuel evaporative emission in the fuel tank is detected by means of a magnetic flux detector or so forth. A control circuit is responsive to the pressure of the fuel evaporative emission reaching 15 mmHg, for example, while the communication passage (21) is held closed, to open the communication passage (21). On the other hand, the control circuit closes the communication passage when the pressure of the fuel evaporative emission becomes lower than or equal to 8 mmHg. Depending on a period, in which the communication passage (21) is held open, the flow rate of the fuel evaporative emission is calculated.Type: GrantFiled: April 7, 1992Date of Patent: November 9, 1993Assignees: Nippondenso Co., Ltd., Ubukata Industries Co., Ltd.Inventors: Akihiro Nakashima, Hisashi Iida, Shigenori Isomura, Hideki Koseki, Takao Tsuji
