Abstract: A capless refueling mechanism includes a fill opening side shut-off valve disposed near the fill opening, and a fuel tank side shut-off valve disposed nearer to a fuel tank than the fill opening side shut-off valve. The refueling auxiliary device has a guide pipe section and a funnel section, and pressing of the fill opening side shut-off valve and the fuel tank side shut-off valve via an end of the guide pipe section causes a valve element to be moved away from a seat portion and insertion of a nozzle into the funnel section allows refueling. The outer circumferential surface of the guide pipe section is provided with an enlarged diameter section that regulates a valve opening degree of the valve element of the fuel tank side shut-off valve.

Abstract: A microcontroller includes a CPU (Central Processing Unit), a data input unit, and an oscillator that supplies a clock signal in response to operational modes of the microcontroller. The operational modes include a STOP mode, a SNOOZE mode and a RUN mode, in the STOP mode, the oscillator and the CPU are stopped, in the RUN mode, the CPU and the data input unit operate using the clock signal supplied from the oscillator, and in the SNOOZE mode, the oscillator starts and supplies the clock signal to the data input unit when the data input unit receives first data, and the microcontroller switches to the RUN mode after the data input unit receives second data using the clock signal.
