| Summary: | Efficient and reliable catalytic converter fast lightoff technology is an important task for automotive engineers to meet the challenge of ever-stringent emission standards. Different approaches have been investigated in recent years as summarized in the literature review. A new method called high values of ignition retard (HVIR)control is proposed in this study, which aims to largely increase the exhaust gas energy for catalyst heating so as to achieve early catalyst lightoff. |
