    • A fuel injection control device for a multi-fuel engine includes a corrector and a reviewer. An alcohol concentration learning unit is provided to learn an alcohol concentration in an injected fuel based on an oxygen concentration detected in an exhaust gas. A fuel injection amount controller is provided to control a fuel injection amount based on a learning value corresponding to the oxygen concentration. The corrector is configured to reduce the fuel injection amount corresponding to the learning value for a predetermined time period when the learning value is higher than a threshold value when an engine is started. The reviewer is configured to review the learning value to provide a revised learning value based on the oxygen concentration while the corrector reduces the fuel injection amount. The fuel injection amount is controlled based on the revised learning value after the corrector reduces the fuel injection amount.
    • 一种用于多燃料发动机的燃料喷射控制装置,包括校正器和检查器。 提供了一种酒精浓度学习单元,用于基于在废气中检测到的氧浓度来了解喷射的燃料中的酒精浓度。 提供燃料喷射量控制器,用于基于与氧气浓度对应的学习值来控制燃料喷射量。 校正器被配置为当发动机起动时学习值高于阈值时,将与学习值对应的燃料喷射量减小预定时间段。 审查者被配置为审查学习值以提供基于氧浓度的修正学习值,同时校正器减少燃料喷射量。 在校正器减少燃料喷射量之后,基于修正后的学习值来控制燃料喷射量。

    • A printer (100) for printing based on a print job signal sent from a data processing device (200) registers print job signal sending sources and a message corresponding to each sending source in memory (111, 112). A controller (113) detects whether the sending source of a received print job signal is registered in memory. If the sending source is registered, a messaging unit (110, 111) outputs a corresponding message. Sending sources that are permitted to print can also be registered in memory (111, 112). In this case, the controller (113) detects whether the sending source of a received print job signal is registered in memory, and instructs the printer (110) to print only when the sending source is registered as permitted to print.
    • 用于基于从数据处理装置(200)发送的打印作业信号进行打印的打印机(100)将打印作业信号发送源和与每个发送源对应的消息记录在存储器(111,112)中。 控制器(113)检测所接收的打印作业信号的发送源是否被登记在存储器中。 如果发送源被注册,则消息传送单元(110,111)输出相应的消息。 允许打印的发送源也可以在存储器(111,112)中注册。 在这种情况下,控制器(113)检测所接收的打印作业信号的发送源是否被登记在存储器中,并且仅当发送源被注册为允许打印时才指示打印机(110)进行打印。
