摘要： A fuel-vapor emission control apparatus is mounted on a vehicle having an internal combustion engine and a fuel tank. The engine has a plurality of cylinders and is supported by engine mounts. The fuel-vapor emission control apparatus purges fuel-vapor in the fuel tank and supplies the purged fuel-vapor to the engine. The apparatus includes a vacuum switching valve, sensors and an electronic control unit. The vacuum switching valve controls the amount of purged fuel-vapor that is supplied to the engine. The sensors detect the operating state of the engine. The electronic control unit duty controls the vacuum switching valve in accordance with data from the sensors. The control unit also serves to suppress resonance of the engine and the engine mounts when purged fuel-vapor is being supplied to the engine.

Therefore, it is possible to suppress a rapid cooling of the catalyst, and it becomes possible to maintain a temperature of the carrier retention unit at a lower temperature than a temperature of the catalyst.

摘要： A fuel tank is divided into a fuel chamber and an air chamber by a bladder diaphragm. Under a condition that both the amount of intake air Ga and the engine revolution speed NE of an internal combustion engine are kept at constant values, a vapor concentration correction factor FGPG during a fuel injection duration TAU is calculated based on a change in the air-fuel ratio detected when gas is purged from the air chamber toward an intake passage of the engine. Based on the vapor concentration correction factor FGPG, it is determined whether there is fuel leakage from the fuel chamber to the air chamber. With this determination technique, a fluctuation in the air-fuel ratio is not caused by a situation where the engine is in a transitional state, during fuel leakage detection, so that the vapor concentration correction factor FGPG assumes a proper value corresponding to the vapor concentration in the air chamber. Therefore, a false determination regarding the presence/absence of fuel leakage from the fuel chamber to the air chamber is prevented.
摘要翻译：燃料箱通过气囊隔膜分成燃料室和空气室。在内燃机的进气量和发动机转速NE都保持为恒定值的条件下，基于空燃比的变化来计算燃料喷射持续时间TAU期间的蒸汽浓度校正系数FGPG，当气体从空气室朝向发动机的进气通道被清除时，检测到燃料比。基于蒸气浓度校正因子FGPG，确定是否存在从燃料室到空气室的燃料泄漏。利用该判定技术，在燃料泄漏检测时，由于发动机处于过渡状态的情况，不会引起空燃比的波动，所以蒸气浓度校正系数FGPG取相当于蒸气浓度的适当值在空气室。因此，能够防止燃料从燃料室向气室的泄漏的存在/不存在的错误判定。

摘要： A fuel vapor feed controlling apparatus of a lean burn internal combustion engine suppresses either one of a rich misfire or a surge when fuel vapor is fed into the engine. A purge controlling unit controls an amount of fuel vapor fed from a fuel reservoir to the engine in response to an operational condition of the engine. A first compensation unit compensates the amount of fuel vapor such that an engine revolution speed of the engine may be identical with a target revolution speed. The purge controlling unit performs a purge control based on a compensation value compensated by the first compensation unit.

摘要： A target air amount for achieving a requested torque is back-calculated from the requested torque using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from operation in the first air-fuel ratio to operation in the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, the target air-fuel ratio is changed in accordance with an air-fuel ratio efficiency within the range from the first air-fuel ratio to the second air-fuel ratio. The air-fuel ratio efficiency is calculated based on a proportion of the requested torque relative to a torque that can be achieved by means of a current estimated air amount under the theoretical air-fuel ratio and the optimal ignition timing.
