Abstract
Application of an electric heater is one of attractive methods for active regeneration in DPF systems, but its application has been limited by the capacity of electric power available in vehicles. This study was focused on intake throttling to reduce electrical energy required in the electrical heated DPF system. As results, this study showed the decrease of $30\~50\%$ of intake air mass flow rate and the increase of $20\~60^{\circ}C$ of exhaust gas temperature by the proper control of intake throttling. These intake throttling effects was helpful for regenerable temperature achievement.
