A comparative analysis is carried out between common light-off temperature meth-od and uncommon light-off ties method for evaluating the light-off performance.
对起燃特性评价试验中常用的起燃温度法和不常用的起燃时间法进行了对比分析。
It may effectively reduce the HC emissions to use a catalyst with low light-off temperature, close-coupled catalyst, HC traps, second air injection and electrically heated catalyst.
采用如低起燃温度催化剂、密耦催化剂、HC捕集器、二次空气注入和电加热催化剂等在内的排气后处理技术，可以有效地减少污染物尤其是HC的排放。
