日产“地平线”车上目前装上了一种由DuPont公司制造的空气流量计，这种流量计的外壳是由热塑性聚酯制成，取代了以往的铝压铸外壳。这种热塑性聚酯外壳的使用，减化了生产过程，在生产中只需加热即可连接，而不再需要用优质钢进行焊接。该空气流量计外壳的机械强度与铝制外壳
The Nissan “Horizon” car is now fitted with an air flow meter manufactured by DuPont, which is made of thermoplastic polyester and replaces the old aluminum die-cast housing. The use of this thermoplastic polyester casing reduces the production process and requires only heating in the production to connect without the need for high quality steel for welding. The air flow meter housing has a mechanical strength with an aluminum housing
