The present invention is directed toward an enhanced very high volt electrolyte for use in electrolytic capacitors. According to this, steady state vibration and transient state vibration generated from a tub assembly during an entire process for washing laundry are prevented from being transmitted to a cabinet, thereby minimizing noise leaked to outside. The maximum period from simultaneous injection, after start of cranking, until simultaneously injected fuel is sucked into all cylinders #1 to #4 is set as an injection prohibition period t. The eighteen holes include nine pairs of holes.
