摘要
民用车辆颗粒捕集器进行热再生时,排气温度高达600℃以上,容易引起火灾,对周围环境带来安全隐患;军事用途发动机排气温度过高,容易呈现出明显红外特征,被敌红外侦测装置捕捉进而遭受打击。因此,对发动机尾气进行降温,能够提高民用车辆环境安全性和军用车辆红外隐蔽性,符合军民两方面需求。
The temperature of exhaust gas can exceed 600℃ when the DPF was renewed on vehicle. It＇s dangerous to surrounding and easy to cause fire disaster. The temperature of exhaust gas from military engine is higher than normal temperature, it＇s easy to demonstrate IR and was bombed. So, in order to improve the environmental safety and shelter. It＇s necessary to lower the temperature of exhaust gas of engine. It can satisfy the requirements of civil and military.
