Does the Lavida 1.4T have a particulate filter?
2 Answers
The Lavida 1.4T is equipped with a particulate filter, and there are currently two models of the Lavida 1.4T available for sale. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Working principle of the particulate filter: 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 trap through a dedicated pipe. After passing through the densely arranged bag filters inside, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then expelled. To check whether the Lavida 1.4T is equipped with a particulate filter, you can use the following three methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe to see if there is a cylindrical section. If there is, that is the particulate filter.
As someone passionate about automotive technology, I'm always curious about the details of vehicle emission systems. The Lavida 1.4T models, especially those released after 2019 that comply with the China VI emission standards, are indeed equipped with a Gasoline Particulate Filter (GPF). This is because the China VI standards require gasoline vehicles to reduce particulate emissions, and the GPF is specifically designed to capture fine particles in the exhaust, preventing pollutants from being directly released into the air. In practical driving, the GPF may require periodic regeneration, which involves running the engine under high load during highway driving to clear accumulated particles. Otherwise, clogging can reduce power response and even trigger a warning light. I recommend Lavida owners to drive more on highways rather than just cruising at low speeds in the city. Additionally, regular maintenance and inspection of the exhaust system are essential to keep the GPF functioning properly and extend the vehicle's lifespan, benefiting both environmental protection and performance.
