The system is applied to an engine having an injection system, a fuel feed line and a cooling system, by means of a cooling fluid which circulates, through hot fluid ducts and cold fluid ducts, through the engine and through a heat exchanger. The first buffer unit stores therein pixel signals of the input image on every line in a main scanning direction thereof. The at least one rapid release contaminant is extracted from the subsurface source area, resulting in solidification of the dense non-aqueous phase liquids remaining in the subsurface source area. Alternatively, the cancelling command is a duplicate notify command.
