Abstract

The invention provides a vehicle-mounted DPF on-line regeneration system and a control method. The vehicle-mounted DPF on-line regeneration system mainly comprises a post-processing system, an NTP generation system, an NTP generator air inlet system, an NTP generator cooling system, a power supply device, a diesel engine system and a control module. The air inlet system is used for providing air for the NTP generation system, the system temperature is controlled by a cooling system, the NTP generation system is generated by discharging modules in the system and provides NTP active substances for the post-processing system through a NTP nozzle. The power supply device provides different voltages for each discharging module in the NTP generation system. The control module controls the wholesystem through various sensors and pumps. The diesel engine system can be coupled with the NTP system and the post-processing system in a regeneration mode to realize the control and optimization of the vehicle-mounted DPF on-line regeneration system. The vehicle-mounted DPF on-line regeneration system and the control method can effectively improve the efficiency of NTP generation system and the efficiency of DPF regeneration, can regenerate DPF in the running process of an engine, and is closer to the practical application.

Description

technical field [0001] The invention belongs to the technical field of post-treatment of diesel engine exhaust, and in particular relates to a DPF online regeneration system utilizing NTP technology. Background technique [0002] As an internal combustion engine different from gasoline engines, diesel engines are more economical and have high thermal efficiency, and are widely used in every corner of industry, agriculture and daily life. However, the huge number of diesel vehicles also brings many environmental problems. Carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) in their emissions will have a negative impact on the environment and people. cause certain harm. The organic soluble components and polycyclic aromatic hydrocarbons in PM have certain carcinogenicity, and the inhalation of PM will increase the mechanical recombination of human lungs and cause harm to human heart and respiratory system. NOx is the main factor that ca...
