The durability of hexagonal cell and square cell SiC diesel particulate filters (DPFs) were evaluated in the mechanical strength test and the drop to idle test (DTIT test). Results show that the b-axis and c-axis mechanical strengths of the hexagonal cell DPF are almost equal, and the values of Young’s modulus of hexagonal cell DPF are lower compared with those of the square cell DPF. In addition, if the same soot amount is burned in drop to idle test, the difference between minimum and maximum temperatures inside hexagonal cell DPF is smaller than that of square cell DPF. |
