摘要： A butterfly valve restricts flow passage areas of a purge passage and a blow-by gas passage by the same degree. A first pressure sensor detects variation in pressure of the purge gas, which is generated by the butterfly valve. A second pressure sensor detects variation in pressure of the blow-by gas, which is generated by the butterfly valve. Since a fuel vapor concentration of the blow-by gas is lower than that of the purge gas, the blow-by gas can be treated as air of 100%. Hence, the fuel vapor concentration is calculated based on the variations in pressure detected by the first pressure sensor and the second pressure sensor.
摘要翻译：蝶阀将吹扫通道和窜气通道的流路面积限制在相同的程度。第一压力传感器检测由蝶形阀产生的吹扫气体的压力变化。第二压力传感器检测由蝶形阀产生的窜气的压力变化。由于窜缸气体的燃料蒸气浓度低于净化气体的燃料蒸汽浓度，所以窜气可以被处理为100％的空气。因此，基于由第一压力传感器和第二压力传感器检测到的压力变化来计算燃料蒸气浓度。

摘要： A PCV valve is arranged in an outflow passage. An ECU controls rotation of a motor such that an opening degree of the PCV valve increases in response to an increase in an opening degree of a throttle valve. The outflow passage connects an interior of a head cover of an engine to a portion of an intake air passage located on a downstream side of the throttle valve. The outflow passage recirculates blow-by gas leaked from a combustion chamber into an interior of a crankcase to the portion of the intake air passage located on the downstream side of the throttle valve. An inflow passage connects the interior of the head cover to a portion of the intake air passage located on an upstream side of the throttle valve. The inflow passage conducts intake air from the intake air passage to the interior of the head cover.

摘要： A communication passage for generating braking negative pressure is connected to an air passage for respective cylinders at a downstream side of a throttle valve. An air ejector is provided in a negative pressure pipe, to which communication passages for the respective cylinders are converged. A negative pressure passage for a brake booster is connected to the air ejector at a side of suction gas via a check valve. A passage for PCV gas and an intake air branched passage for bifurcating a part of the intake air from a surge tank at an upstream side of the throttle valve are connected to a driving gas side of the air ejector, wherein a negative pressure control valve is provided in the intake air branched passage. The PCV gas and the part of the intake air are forced to flow into the driving gas side of the air ejector, so that the air ejector functions as a vacuum pump. As a result, the braking negative pressure for the brake booster can be surely reduced to a target negative pressure.

摘要： An air-intake device having a noise reduction mechanism includes a surge tank connected to an intake manifold for introducing intake air into an internal combustion engine, an air duct connected to an upstream end of the surge tank and a resonator connected to the surge tank and the air duct. The resonator forms a resonator chamber connected to both the surge tank and the air duct. The surge tank is separated from the resonator chamber by a first vibrating member, and the air duct is separated from the resonator chamber by a second vibrating member. The noises in the surge tank are offset or reduced by resonating vibrations of the first vibrating member, and the noises in the air duct are offset or reduced by resonating vibrations of the second vibrating member. Thus, the intake air noises are effectively reduced by a simple combination of the resonator and the vibrating members.

摘要： A noise reduction apparatus includes an intake passage forming member defining an intake passage, a resonator, and a vibration film. Intake air drawn into a combustion chamber of an internal combustion engine flows through the intake passage. The resonator has an inner volume part branching from the intake passage. The vibration film is placed to separate the intake passage from the inner volume part. The vibration film is vibrated by a sound pressure of a sound that is generated in the combustion chamber and that propagates through the intake passage. The vibration film has a projection part, which separates the vibration film into an inner vibration film part and an outer vibration film part.
