    • 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.
    • 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。

    • PROBLEM TO BE SOLVED: To detect a correct purge gas flow rate in consideration of concentration of evaporated fuel contained in purge gas.
      SOLUTION: An ECU 40 calculates reference differential pressure ΔPb from a map of intake pipe pressure Ps, differential pressure ΔPv between before a purge valve and after the purge valve, and differential pressure ΔP100 of air of 100%. In the ECU 40, the calculated reference differential pressure ΔPb is divided by the differential pressure ΔP100 of air of 100% to calculate a reference differential pressure ratio ΔPr, and then an evaporated fuel flow rate Fhc is calculated. The ECU 40 calculates a reduced flow rate ΔFre of the purge gas with respect to a purge gas flow rate F100 of air of 100% by using the reference differential pressure ratio ΔPb, and calculates a true purge gas flow rate Fp. The ECU 40 calculate an air flow rate Fair by using the calculated true purge gas flow rate Fp and evaporated fuel flaw rate Fhc.

    • 要解决的问题:考虑到吹扫气体中所含的蒸发燃料的浓度来检测正确的净化气体流量。 解决方案:ECU40根据进气管压Ps的图,净化阀之前和净化阀之间的差压ΔPv以及100%的空气压差ΔP100计算基准压差ΔPb。 在ECU40中,将计算出的基准压差ΔPb除以100%的空气压差ΔP100,计算基准压差比ΔPr,求出蒸发燃料流量Fhc。 ECU40通过使用基准压差比ΔPb计算出吹扫气体相对于空气的吹扫气体流量F100的降低的流量ΔFre,并计算真正的净化气体流量Fp。 ECU40通过使用计算出的真实吹扫气体流量Fp和蒸发的燃料缺陷率Fhc来计算空气流量Fair。 版权所有(C)2004,JPO

    • PROBLEM TO BE SOLVED: To provide an evaporated fuel processing device for an internal combustion engine in which the evaporated fuel is purged from a canister into the suction passage of the engine so that the engine can operate as specified.
      SOLUTION: The evaporated fuel processing device of the internal combustion engine is equipped with the canister 23 for capturing temporarily the evaporated fuel generated in a fuel tank 26 of the engine, a purging passage 22 to couple the canister with the engine suction passage for purging the evaporated fuel captured in the canister into the suction passage 11, and a purge control valve 24 installed in the purging passage for controlling the amount of the evaporated fuel purged from the canister into the suction passage. The device is equipped with a learning function to learn the canister condition learning value representing the amount of the evaporated fuel captured in the canister after the purge control valve is actuated. The target opening of the purge control valve is set on the basis of the canister condition learning value learnt after the actuation directly before of the purge control valve.

    • PROBLEM TO BE SOLVED: To efficiently liquefy fuel vapor by constituting a vapor passage with a plurality of parallel passages, storing a liquefied fuel in a liquid reservoir inside a cooler covered with a thermal insulating means, and adjusting a fuel flow circulated from the liquid reservoir to a fuel tank. SOLUTION: Cooling passages 271, 272 are arranged side by side at right side and left side of a separator 26, thereby reducing pressure loss of the passages and improving a cooling property at the same time. Vapor fuel generated inside a fuel tank is introduced via a fuel vapor passage 10 to a cooler 20. The fuel vapor passes through the cooling passages 271, 272 and is condensed and liquefied. The liquefied fuel is stored in a liquid reservoir 201 at a lower part. Since the liquid reservoir 201 is covered with a thermal insulating member 24 and cooled, the fuel is prevented from reevaporating. A predetermined amount of the liquefied fuel can be stored, though a temperature of the fuel tank is decreased, the liquefied fuel is stored till an operation state with sufficient power is realized. Accordingly, a large amount of fuel vapor such as in idle at high temperature is generated, and consumption power is minimized to recover the fuel vapor efficiently.
