Zeolite catalysts must be loaded onto carriers in order to reduce vehicle exhaustresistance.
分子筛催化剂负载在成型的载体上，可以降低汽车尾气的阻力。

The test results show that it can recover much more exhaust heat, and less exhaustresistance and lower noise than the original one.
实验结果表明，该装置回收排气余热量大，和原消声器相比，排气阻力较小，降噪效果明显。

A compression process of times compressed, high thermal efficiency. 3 no suction and discharge valves, the intake and exhaustresistance loss is almost zero.
