摘要
分析发动机水箱产生故障的常规原因。采用实境模拟,重现在通电或者有电位差的环境下,发动机冷却液与电感式液位传感器的相互作用。在此环境下,电位差会诱发铁锈并吸附发动机冷却液中的极性添加剂使其从发动机冷却液中析出,造成导电能力下降,从而导致仪表报警。只有使用机械式液位传感器或者使用添加了非常规添加剂的发动机冷却液,才能避免类似故障。
Conventional reasons for failures of the engine tank were analyzed. Adopting scenario simulation, an electricity environment was reproduced, then the interactions between the engine coolant and the inductance type liquid level sensor could be seen. The potential difference caused rust and precipitation of the adsorbed polar additives from the engine coolant. It led to the decrease of the conductive ability. That resuhed in alarm of the instrument. To avoid such kind of failure, mechanical level sensor or engine ennlant with insulating material could be used.
