提出了一种不解体诊断中冷器技术状态的新方法，通过检测中冷器增压空气流动阻力、空气和冷却水进、出口温度等，提取反映中冷器技术状态的特征参数，成功地诊断了中冷器的技术状态及典型故障．
A new method of diagnosing the technical condition of the intercooler without disintegration is proposed. By detecting the flow resistance of intercooler charge air, the inlet and outlet temperatures of air and cooling water, the characteristic parameters reflecting the technical condition of the intercooler are extracted successfully Diagnosed intercooler technical status and typical failure.
