• A fuel burner after the turbo to increase the exhaust temperature.
• A catalytic oxidizer to increase the exhaust temperature, with after injection.
• Resistive heating coils to increase the exhaust temperature.
• Microwave energy to increase the particulate temperature.
Not running the regeneration cycle soon enough increases the risk of engine
damage and/or uncontrolled regeneration (thermal runaway) and possible DPF
