SIC silicon carbide DPF Diesel Particulate Filter Filter

Product introduction

Diesel engine exhaust contains carbon particles of black smoke, they will enter in the particle catcher made of SiC-DPF filters through a special pipeline, so the carbon smoke particles are adsorbed on the filters; When the amount of particles adsorption reaches a certain amount, the end burner will automatically ignite combustion, and burn the adsorbed carbon particles, into harmless carbon dioxide. The whole device is designed as a double chamber structure, filtration and regeneration are carried out separately, so that filtration and regeneration do not interfere with each other, no matter the engine is in any situation can work automatically.
