Description

technical field [0001] The invention relates to the field of auxiliary equipment for automobile use, in particular to a pulse control purification system for diesel vehicle exhaust gas. Background technique [0002] After the car has driven to a certain mileage, carbon deposits and sludge will be produced in the gasoline engine or diesel engine. If it is not removed, the combustion performance of the engine will be reduced, resulting in increased fuel consumption and excessive exhaust gas. In the existing technology, the carrier technology is used to adjust and activate the ignition and fuel injectors, and a more reasonable ignition timing diagram is established in the engine control module to reduce invalid fuel injection, improve the degree of fuel atomization, and make the mixture burn more fully , this technical solution can effectively treat the carbon deposits in the vehicle cylinder and exhaust emissions at the same time, but there is still room for improvement in thi...
