This in turn raises the temperature of the GPF to around 400c – 700c, igniting the soot contained within the filter. In conditions where this is not possible, the vehicles engine management systems alter timing causing it to run lean. This “lean” burn increases oxygen and therefore GPF operating temperatures, allowing regeneration to occur.
