System for assisting the regeneration of an exhaust gas purifying system comprised in the exhaust pipe of a vehicle engine |
摘要 |
The particle filter is regenerated by periodically cutting the fuel injection to one of the engine cylinders to increase the proportion of oxygen delivered into the exhaust. The higher oxygen levels give improved combustion of the particles trapped in the particle filter, regenerating the filter more effectively.
