What is a Volkswagen Particulate Filter?
1 Answers
Introduction to the Volkswagen Particulate Filter: 1. The automotive particulate filter is a ceramic filter installed in the diesel engine's exhaust system, designed to capture particulate emissions before they enter the atmosphere. 2. The particulate filter can reduce engine-generated soot by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Here is some related information about automotive particulate filters: 1. Working Principle: For instance, a diesel particulate filter coated with metals such as platinum, rhodium, and palladium allows the black smoke containing carbon particles emitted by the diesel engine to enter the engine's exhaust particulate filter through a specialized pipe. Inside, a densely arranged bag-type filter captures the carbon smoke particles on a filter made of metal fiber felt. When the accumulation of particles reaches a certain level, a burner at the end automatically ignites, burning off the carbon smoke particles adhered to it, converting them into harmless carbon dioxide that is then expelled. 2. Functional Introduction: With the assistance of the engine control system, it not only controls the quantity of particulate emissions but also regulates the emission levels of pollutants such as hydrocarbons and other harmful gases. The regeneration or purification function of the filter must be completed on a controlled basis to prevent the filter from becoming clogged with soot. After the purification cycle concludes, any residual dust or filter residue is ultimately removed manually during routine maintenance.
