摘要： PROBLEM TO BE SOLVED: To provide a vaporized fuel treating device in which the concentration of a fuel vapor is accurately measured in real time. SOLUTION: A purge passage 15 and a blow-by gas discharge passage 23 are restricted by a butterfly valve 36. The amount of the pressure of a purge gas changed by the butterfly valve 36 is detected by a first pressure sensor 37, and the amount of the pressure of a blow-by gas changed by the butterfly valve 36 is detected by a second pressure sensor 38. Since the blow-by gas is lower in fuel vapor concentration than the purge gas, it is regarded as 100% air, and the fuel vapor concentration is calculated based on these two changed amounts of pressure detected by the pressure sensors 37, 38. Since these two changed amounts of pressure can be measured in real time, the fuel vapor concentration can be provided in real time. Also, since the effects of the atmospheric conditions are canceled, the concentration of the fuel vapor can be accurately measured. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种实时准确测量燃料蒸气浓度的汽化燃料处理装置。解决方案：吹扫通道15和窜气排放通道23由蝶形阀36限制。由蝶阀36改变的净化气体的压力量由第一压力传感器37检测，并且由第二压力传感器38检测由蝶阀36改变的窜气的压力量。由于窜缸气体的燃料蒸气浓度低于吹扫气体，因此被认为是100％空气，并且基于由压力传感器37,38检测的这两个改变的压力来计算燃料蒸气浓度。由于这两个改变的压力量可以实时测量，所以可以实时地提供燃料蒸气浓度。此外，由于大气条件的影响被消除，所以可以精确地测量燃料蒸气的浓度。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel vapor processing system capable of forcedly purging a canister 3 without consuming electric power even in a low intake pipe negative pressure engine. SOLUTION: When intake pipe negative pressure is generated as a throttle valve 6 is closed, the intake pipe negative pressure is introduced into a first chamber 41 to move a partition wall 7, and the canister 3 is purged by that force to suck fuel vapor (purge air) into a second chamber 42. After that, when the throttle valve 6 is opened to lower the intake pipe negative pressure, the intake pipe negative pressure is released from the first chamber 41, and the partition wall 7 is moved by a spring or the like, so that the fuel vapor in the second chamber 42 is released to an intake pipe 1. The intake pipe negative pressure generated in the intake pipe 1 when the throttle valve 6 is closed, is thus effectively utilized, and a purge pump 5 is driven using the intake pipe negative pressure as a drive source, thereby the canister 3 can be purged without consuming electric power.
摘要翻译：要解决的问题：提供即使在低进气管负压发动机中也能够消耗电力而能够强制吹扫罐3的燃料蒸气处理系统。解决方案：当节流阀6关闭时，当进气管负压产生时，进气管负压被引入第一室41以移动分隔壁7，并且通过该力吹扫罐3以吸入燃料蒸气（吹扫空气）进入第二室42.此后，当节流阀6打开以降低进气管负压时，进气管负压从第一室41释放，分隔壁7由弹簧使得第二室42中的燃料蒸汽被释放到进气管1.因此有效地利用了当节流阀6关闭时在进气管1中产生的进气管负压，以及净化泵使用进气管负压作为驱动源驱动5，从而可以在不消耗电力的情况下清洗罐3。

摘要： PROBLEM TO BE SOLVED: To provide a fuel vapor leakage inspection apparatus in which a fuel vapor is prevented from flowing into the atmosphere during a leakage inspection by stopping the leakage inspection when the adsorbing capacity of an adsorbent is lowered. SOLUTION: When the leakage inspection is performed for a fuel vapor treatment system, a discharged fuel vapor concentration calculated by an ECU 30 beforehand according to a signal detected by an air-fuel ratio sensor 22 is read out. The ECU 30 calculates the concentration of the discharged fuel vapor discharged from a canister 50 into an intake pipe 12 based on the air-fuel ratio of exhaust gases detected by the air-fuel ratio sensor 22 and a theoretical air-fuel ratio. The adsorbed amount of the fuel vapor adsorbed by the adsorbent 52 in the canister 50 is calculated based on the concentration of the discharged fuel vapor. When the calculated adsorbed amount of fuel vapor is larger than a predetermined amount, if fuel supply into a fuel tank is detected, it is determined that a large amount of fuel vapor is adsorbed to the adsorbent 52 and the adsorbing capacity of the adsorbent 52 is lowered. Then, the leakage inspection is stopped. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种燃料蒸气泄漏检查装置，其中当吸附剂的吸附能力降低时，通过停止泄漏检查，在泄漏检查期间防止燃料蒸汽流入大气。解决方案：当对燃料蒸气处理系统进行泄漏检查时，读出由ECU30预先根据由空燃比传感器22检测到的信号计算出的排出的燃料蒸气浓度。 ECU30基于由空燃比传感器22检测出的排气的空燃比和理论空燃比，计算从罐50向进气管12排出的排出的燃料蒸气的浓度。基于排出的燃料蒸气的浓度计算吸附剂52在罐50中吸附的燃料蒸汽的吸附量。当所计算的燃料蒸汽吸附量大于预定量时，如果检测到燃料箱中的燃料供应，则确定吸附剂52吸附大量的燃料蒸气，吸附剂52的吸附能力为降低。然后，泄漏检查停止。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vaporized fuel leak inspecting device that stops leak inspection when adsorption ability of adsorbent is deteriorated for preventing vaporized fuel from flowing into atmospheric air during leak inspection. SOLUTION: In executing leak inspection in a vaporized fuel processing system, concentration of discharged vaporized fuel preliminarily determined by an ECU 30 based on a detection signal of an air-fuel ratio sensor 22 is read. The ECU 30 determines the concentration of discharged vaporized fuel discharged from a canister 50 into an intake tube 12 based on deviation between an air-fuel ratio in exhaust gas detected by the air-fuel ratio sensor 22 and a theoretical air-fuel ratio. Adsorption quantity of vaporized fuel adsorbed in the adsorbent 52 in the canister 50 can be determined based on the concentration of discharged vaporized fuel. In a case where adsorption quantity of vaporized fuel determined is larger than prescribed quantity, it is determined that a mass quantity of vaporized fuel is held adsorbed in the adsorbent 52, and that the adsorption ability of the adsorbent 52 is deteriorated, and leak inspection is stopped.

摘要： PROBLEM TO BE SOLVED: To provide a filter for a canister for reducing fuel vapor blown off in the atmosphere by removing the fuel vapor passing through the canister.
SOLUTION: A first housing chamber 41 and a second housing chamber 42 filled with adsorbents 44 and 45 of the canister 10 communicate with a filter chamber 43 having an atmospheric port 46. A filter 50 is housed in the filter chamber 43. The filter 50 has an activate charcoal part sandwiched between holding layers composed of nonwoven fabric. Among hydrocarbon included in fuel, hydrocarbon unadsorbable/unremovable by the adsorbents 44 and 45 of the canister 10 and having a small number of carbon is adsorbed and removed by the activated charcoal part of the filter 50 even when passing through the adsorbents 44 and 45 of the canister 10. Thus, the fuel vapor blown off in the atmosphere can be reduced.

摘要： PROBLEM TO BE SOLVED: To detect any leakage of evaporative systems with high accuracy even when a very large amount of fuel remains. SOLUTION: The time required for the pressure in evaporative systems 6, 7, 8, 10 and 11 to drop from a first predetermined pressure P0 to a second predetermined pressure P1 is measured for a state in which a reference orifice 17 as a reference leak hole is included in a leaking part and a state in which no reference orifice is included, respectively. By comparing the required time T2 in the state in which no reference orifice is included with a reference determination time of the required time T1 in the state in which the reference orifice is included, multiplied by a predetermined coefficient, a state of leakage is diagnosed without being affected by the atmospheric temperature or the like. The pressure drop state is adequately indicated even when a very large amount of fuel remains by using the time from the first predetermined pressure P0 to the second predetermined pressure P1 as an index of the pressure drop state.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a direct-injection engine or an engine mounted on a hybrid vehicle has a throttle valve often largely opened during operation and an inlet pipe subjected to low negative pressure to provide insufficient capability for recovering an evaporating fuel absorbing canister, which should be supplemented. SOLUTION: A second purge line 27 opening to a suction port 8 of each cylinder is provided for purging the canister 18. Numeral 24 is a first purge line opening to a common inlet pipe 12, numeral 23 is a first purge valve and numeral 28 is a second purge valve. Since an inlet port 8 of each cylinder has inlet negative pressure higher than the inlet pipe 12 during an intermediate or high load, high purging capability is established in this condition. During a low-load operated condition such as idling, the first purge line 24 is utilized as conventional. By providing one-way valves in the purge lines 24, 27, canister purging operations are performed in the order of the line having higher negative pressure and the maximum purge flow is therefore provided when both of them operate together.
摘要翻译：要解决的问题为了解决直接喷射发动机或安装在混合动力车辆上的发动机具有在运行中经常大大打开的节流阀和经受低负压的进气管以提供不足以回收蒸发燃料的能力的问题吸收罐，应补充。解决方案：提供通向每个气缸的吸入口8的第二吹扫管线27，用于清洗罐18.数字24是通向公共入口管12的第一吹扫管线，标号23是第一吹扫阀，数字28是第二个清洗阀。由于每个气缸的入口端口8在中等或高负载期间具有高于入口管12的入口负压，因此在该状态下建立了高清洗能力。在诸如怠速的低负载操作条件期间，如常规使用第一吹扫管线24。通过在净化管线24,27中提供单向阀，以更高负压的管线的顺序执行罐清洗操作，因此当它们两者一起工作时，提供最大吹扫流量。

摘要： PROBLEM TO BE SOLVED: To reduce intake noise in a wide frequency band by utilizing sound waves generated on either one of vibration plates and sound waves generated on the other of them.
SOLUTION: This noise controller is provided with the vibration plates 11 for partitioning a silencer 15 into a main sound pressure generating chamber 13 and a back cavity 14 to suppress intake noise by the "synthetic waves" synthesized by main sound waves given into an intake pipe 2 from the main sound pressure generating chamber 13 and sub-sound waves given into the intake pipe 2 from the back cavity 14 by passing through a back cavity discharge passage 19. Since the sound waves generated in not only the main sound pressure generating chamber 13 but also the back cavity 14 are utilized in this way, quantity of energy to be consumed is suppressed. Since "primary frequency of explosion" and "frequency being multiple of the primary frequency of explosion" appear in the "synthetic wave" in the same way as in intake noise, the intake noise can be reduced in a wide frequency band.

摘要翻译：要解决的问题：通过利用在振动板中产生的声波和在另一个振动板上产生的声波来减小宽频带中的进气噪声。解决方案：该噪声控制器设置有振动板11，用于将消声器15分隔成主声压发生室13和后腔14，以通过由主声波合成的“合成波”来抑制进气噪声来自主声压产生室13的进气管2和通过后腔排放通道19从后腔14供给到进气管2中的副声波。由于不仅在主声压下产生的声波以这种方式利用发电室13而且后腔14，抑制了消耗的能量。由于与“进气噪音”相同，因为“合成波”中出现“主要爆炸频率”和“频率是爆炸主频倍数”，因此可以在宽频带内降低进气噪声。版权所有（C）2007，JPO＆INPIT
