温度表指示不准的原因及其维修方法不少微型汽车容易出现温度表、燃油表指示不准的故障，根据笔者长期的维修经验，谈一点体会供同行参考。现行微型汽车的仪表大多数使用双金属电热式仪表。它的工作原理是利用绕在双金属片上的线圈通电发热，使双金属片产生形变，带动仪表... Thermometers indicate the reasons for the inaccurate and maintenance methods Many mini cars prone to thermometers, fuel gauge indicates the failure is not allowed, according to the author’s long-term maintenance experience, talk about experience for peer reference. Most current micro-car instruments use bimetallic electric meters. Its working principle is to use the coil around the bimetal energized heating, so that bimetallic deformation, led the instrument ...
