Abstract

The invention provides an automotive water cooled type NTP generation system which comprises a power supply part, an NTP generator, a diesel engine system, an air inlet and outlet system and a cooling system. The power supply part comprises a diesel engine storage battery, an inverter, an intelligent electronic impact machine, a voltage regulator and an oscilloscope. The inverter inverts 12 V direct current voltage into 220 V alternating current, and then the voltage regulator and the oscilloscope are used for frequency modulation and voltage regulation. A voltage stabilizing box and an MFC are mounted on the air inlet and outlet system for accurately controlling the air inlet flow. The cooling system uses an infrared thermometer for monitoring the temperature of a discharging area in real time, the flow of a pump is controlled by a feedback circuit, and the temperature of the discharging area is controlled. Active gas generated by the NTP generator is sprayed into an exhaust pipe by a nozzle mounted on the exhaust pipe. According to the automotive water cooled type NTP generation system, not only can NOx in diesel engine exhaust gas be reduced, but also DPF regeneration can be reduced; working is stable, the concentration of a generated active substance is high, the conversion efficiency of harmful gas is high, a catalyst is not required, and the system is free from the limit of fuel quality.

Description

technical field [0001] The invention belongs to the technical field of aftertreatment of diesel engines, in particular to a vehicle-mounted water-cooled NTP generating system. Background technique [0002] With the rapid development of social industry, diesel engines have been more and more widely used in the fields of construction machinery and social transportation, and the resulting environmental problems have become increasingly prominent. In order to reduce the environmental pollution caused by harmful gas emissions from diesel engines, countries have implemented more stringent emission regulations. [0003] NO x PM and PM are the main two kinds of harmful gas emissions from diesel engines, which seriously threaten human health. At present, SCR Selective catalytic reduction, SCR technology can effectively reduce NO x . But its use cost is higher, and the technology is not yet mature. Particulate filter (Diesel particulate filter, DPF) technology is considered to be...
