发明名称 UREA HEATING SYSTEM AND HEATING METHOD THEREOF
摘要 A urea solution heating device prevents freezing of a urea solution by using exhaust gas of an engine. More particularly, a urea solution heating device may use a pressure difference between an exhaust gas pipe and a muffler to bypass the exhaust gas to exchange heat between the exhaust gas and the urea solution. The urea solution heating device may include an exhaust gas pipe, a muffler, a first bypass pipe diverged from the exhaust gas pipe, a urea solution tank to which the bypassed exhaust gas is supplied, a second bypass pipe connected to the muffler, and a heat exchanger, wherein the exhaust gas sequentially flows through the first bypass line, the heat exchanger, and the second bypass line by a pressure difference between the exhaust gas pipe and the muffler. An urea solution heating method is also described.
