A vehicle-mounted water-cooled NTP generation system

Abstract

The invention provides a vehicle-mounted water-cooled NTP generating system, which includes 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 includes a diesel engine storage battery, an inverter power supply, an intelligent electronic impact machine, a voltage regulator and an oscilloscope. The inverter power supply turns the 12V DC voltage into 220V AC, and then the voltage regulator and oscilloscope perform frequency modulation and voltage regulation. The air inlet and outlet system is equipped with a pressure stabilizing box and MFC to precisely control the air intake flow. The cooling system uses an infrared thermometer to monitor the temperature of the discharge area in real time, controls the flow of the water pump through a feedback circuit, and controls the temperature of the discharge area. The active gas produced by the NTP generator is sprayed into the exhaust pipe through the nozzle installed on the exhaust pipe. The invention can not only reduce the NOx in the exhaust gas of the diesel engine, but also regenerate the DPF; the operation is stable, the concentration of the active substance produced is high, the conversion efficiency of harmful gas is high, and no catalyst is used, and the fuel quality is not limited.

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, SCRSelective 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 ...

Problems solved by technology

For example, patent CN201371026Y describes a method for NTP to directly treat diesel engine exhaust gas. Although this method can effectively convert harmful gases from diesel engines, the diesel engine exhaust gas is directly passed into the device, making its working state unstable and the conversion efficiency is not high enough.

Patent CN102678238B describes the control method of using NTP to regenerate DPF to reduce harmful emissions of diesel engines, but does not elaborate on the NTP generator part
