    • PROBLEM TO BE SOLVED: To change valve timing by extremely simple structure, and to provide an excellent engine characteristic.
      SOLUTION: This device is provided with: a first pulley 1 connected to a crank shaft, a second pulley 5 connected to a cam shaft for opening/closing a valve, an endless belt 3 wound on these pulleys 1 and 5, a pair of movable pulleys 6 and 7 for rotatably contacting the outer surface of the belt 3, a supporting member 8 for supporting the pulleys 6 and 7, and a motor 10 and a threaded bar 9 for moving the supporting member 8. Dummy pulleys 2 and 4 are rotatably contacting the inner surface of the belt 3. The movement of the pulleys 6 and 7 changes the rotation speed of the pulley 5 to the pulley 1, to advance or delay the rotation position of the cam shaft to the rotation position of the crank shaft.

    • When a wastegate valve, which opens and closes an exhaust bypass passage bypassing an exhaust turbine, is open, exhaust gases of respective cylinders bypass the exhaust turbine and pass a sensing point of an air-fuel ratio sensor downstream of the exhaust turbine. Accordingly, the exhaust gases of the respective cylinders can be avoided from being mixed by the exhaust turbine, so an influence of an inter-cylinder variation in an air-fuel ratio due to an inter-cylinder imbalance abnormality becomes apt to appear in an output waveform of the air-fuel ratio sensor. Therefore, existence or nonexistence of the inter-cylinder imbalance abnormality is determined based on the output of the air-fuel ratio sensor when the wastegate valve is open. Eventually, the existence or nonexistence of the inter-cylinder imbalance abnormality can be determined accurately, thereby improving detection accuracy of the inter-cylinder imbalance abnormality.
    • 当打开和关闭旁路排气涡轮机的排气旁通通道的废气门打开时,各个气缸的废气旁路排气涡轮并将排气涡轮下游的空燃比传感器的感测点通过。 因此,可以避免各气缸的排气被排气涡轮混合,因此,由于气缸内不平衡异常引起的气缸内的变化对空燃比的影响容易出现在输出 空燃比传感器的波形。 因此,当排气门阀打开时,基于空燃比传感器的输出来确定气缸间不平衡异常的存在或不存在。 最终,可以精确地确定气缸内不平衡异常的存在或不存在,从而提高气缸间不平衡异常的检测精度。

    • An abnormality diagnosis apparatus for an internal combustion engine includes an abnormality diagnosis unit, an other fuel contamination determination unit, and a misdiagnosis prohibition unit. The abnormality diagnosis unit determines whether there is an abnormality in a fuel system based on an output from an exhaust gas sensor mounted on an exhaust duct of the internal combustion engine. The other fuel contamination determination unit determines whether an other fuel contaminates a supply fuel supplied to the internal combustion engine. The misdiagnosis prohibition unit conducts one of (a) changing an abnormality determination condition for the abnormality diagnosis in the fuel system and (b) prohibiting the abnormality diagnosis in the fuel system, when the other fuel contamination determination unit determines that the other fuel contaminates the supply fuel.
    • 一种用于内燃机的异常诊断装置包括异常诊断单元,另一燃料污染确定单元和误诊禁止单元。 异常诊断单元基于安装在内燃机的排气管道上的排气传感器的输出,判定燃料系统是否存在异常。 另一个燃料污染确定单元确定其他燃料是否污染供应到内燃机的供应燃料。 误诊诊断单元进行以下(a)改变燃料系统的异常诊断的异常判定条件和(b)在燃料系统中禁止异常诊断的情况下,另一方的燃料污染判定单元判定另一方的燃料污染了 供应燃料。
