| Abstract: | Reduction of HC emissions at cold-start is a challenge in order to meet the future stringent regulations of ultra low emission vehicles (ULEV). It is becoming a hot research area for automotive SI engine. Successful cold-start with low HC emissions requires a basic understanding of the combustion processes at cold-start of SI engines. A review of HC emissions at cold-start based on the literatures and new researches was presented. The factors which influenced HC emissions at cold-start and the future trends of researches were given. |
