<p>PROBLEM TO BE SOLVED: To avoid the occurrence of a malfunction such as clogging and corrosion caused by freezing by preventing the stagnation of exhaust condensed water into piping.SOLUTION: When a dew condensation generation determination part 51 determines a condition that the dew condensation of exhaust condensed water is generated in piping which is an object to be treated, and also determinations that the condition of the generation of the dew condensation is established, a piping vibration control part 52 controls a transmission via an engine 1 and a TCU 60, and makes the engine 1 and the objective piping induce resonance. By this constitution, the stagnation of the exhaust condensed water can be prevented by discharging the exhaust condensed water in the piping, and the occurrence of a malfunction such as clogging and corrosion caused by freezing can be avoided.</p> |
