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.
【課題】配管内への排気凝縮水の停滞を防止して凍結による詰まりや腐食等の不具合発生を未然に回避する。【解決手段】結露発生判定部51で、処理対象とする配管内に排気凝縮水の結露が発生する条件を判定し、結露発生の条件が成立すると判定したとき、配管振動制御部52で、エンジン1及びTCU60を介して変速機を制御し、エンジン1と対象の配管とに共振を誘発させる。これにより、配管内の排気凝縮水を排出して排気凝縮水の停滞を防止することができ、凍結による詰まりや腐食等の不具合発生を未然に回避することができる。【選択図】図2
