The present invention is to provide a dispensing device comprising a dispenser having an upper channel and a bottom opening for storing liquid cleaner; a connecting cup extended downward from the dispenser including at least one aperture on a bottom thereof; and a float in the connecting cup opposite the bottom opening. When the throttle valve is in the mechanically neutral position, an ignition timing control can be switched in a stepwise manner over a predetermined time period from a regular ignition timing control to a limp-home ignition timing control. The thermal treatment system is configured to apply thermal treatment pulses to a subject. The second set of data elements in accordance with the second data model is mapped to a third set of data elements in accordance with the first data model. The air drives the cylinder and then is exhausted through the air chamber from the air outlet.
