以往的自卸车底板加热结构是解决北方高寒地区在冬季运输含水量较大的散装物料与底板冻结的有效手段;随着柴油车国Ⅳ排放标准的实施,为满足要求,取气位置只能安排在消声器尾管处。本文通过实例验证了国Ⅳ自卸车底板加热后的效果,供国内同行参考与研究。 In the past, the heating structure of the dump truck floor was an effective solution to the freezing of bulk materials and the floor in the alpine region of the north during the winter. With the implementation of the emission standard for diesel vehicles in China, in order to meet the requirements, At the muffler tail pipe. In this paper, we verify the effect of the heating of the IV dump truck floor heating for reference and research by domestic counterparts.
