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.

摘要： An internal combustion engine control apparatus includes a secondary air supply device having a secondary air supply passage that supplies secondary air pumped by an air pump into an exhaust system of an internal combustion engine and an opening/closing unit that opens and closes the secondary air supply passage. A controller provided in the internal combustion engine control apparatus sets the opening/closing unit in an open condition such that the secondary air is supplied to the secondary air supply passage, and then executes foreign matter removal control in which the opening/closing unit is opened and closed. As a result, foreign matter caught in an ASV during AI control is removed immediately. By implementing OBD after removing the foreign matter, detection of an open sticking abnormality caused by foreign matter caught in the ASV is suppressed.

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.

摘要： In an evaporative emission control system, a canister adsorbs fuel vapor sent from a fuel tank of an engine. The canister is connected to an intake air passage through a purge gas passage and a purge control valve. A control circuit employs a pressure sensor to detect the pressure of the canister when the purge control valve is closed and when the pressure of the canister is stabilized. The control circuit carries out a failure diagnosis based on this pressure. Namely, when the pressure of the canister after it is stabilized deviates from the atmospheric pressure by more than a predetermined reference value, the control circuit determines that the canister has failed, i.e., the canister has a leak. Since the diagnosis can be carried out before starting the engine, the diagnosis can be correctly carried out without affecting the operation of the engine.
摘要翻译： 在蒸发排放控制系统中，罐吸附从发动机的燃料箱发送的燃料蒸气。 罐通过净化气体通道和净化控制阀连接到进气通道。 控制电路使用压力传感器来检测当清洗控制阀关闭时以及当罐的压力稳定时罐的压力。 控制电路基于该压力进行故障诊断。 也就是说，当其后的罐的压力稳定后，大气压超过预定的基准值时，控制电路确定罐已经失效，即罐发生泄漏。 由于可以在起动发动机之前进行诊断，所以能够正确地进行诊断，而不影响发动机的运转。
