Does Haval Have a Particulate Filter?
2 Answers
Haval is equipped with a particulate filter. Below is a related introduction to the particulate filter: 1. Working Principle: For instance, the diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine exhaust particulate filter through a dedicated pipeline. It then passes through the densely arranged bag-type filters inside, adsorbing the carbon particles onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, incinerating the adsorbed carbon particles into harmless carbon dioxide that is then discharged. 2. Materials Used: The filter employs an advanced electronic control system, catalytic coating, and fuel-borne catalyst (FBC). This fuel-borne catalyst contains metals such as cerium, iron, and platinum. These materials are added to the fuel in specific proportions and, with the assistance of the engine control system, not only control the quantity of particulate emissions but also regulate the emissions of pollutants such as hydrocarbons and other polluting gases.
As an automotive technology enthusiast, I can confidently say that many Haval models are indeed equipped with particulate filters, especially newer SUVs like the H6 and F7 series. This is due to China's National VI emission standards mandating reduced exhaust pollution, and particulate filters effectively filter out exhaust particulates. A friend of mine driving a diesel Haval encountered clogging issues, but it cleared up after driving a few dozen kilometers on the highway. Occasionally accelerating during normal driving can help maintain the system's lifespan. It's recommended that owners regularly check the dashboard warning lights, avoid prolonged low-speed driving to prevent carbon buildup, and visit a professional repair shop for cleaning when necessary. This device is common in modern vehicles, and Haval, as a mainstream brand, naturally includes it.
