At present oxygen sensors used in controlling the ratio of air and fuel can be divided into three types: oxide semiconductor sensor, oxygen concentration cell type sensor and limiting diffusion current sensors. 目前适用于汽车空燃比控制的传感器主要有三种:氧化物半导体型(TiO2传感器)、浓差电池型(ZrO2氧传感器)、极限电流型。
Aluminum air metal fuel cell is ideal for the new type power batteries because of its large theoretical capacity, high specific energy, abundant resources and pollution-free. 铝金属燃料电池理论容量大、比能量高、资源丰富、无污染,是理想的新型动力电池。
