Which Cars Have a Particulate Filter?
2 Answers
Most Japanese car models do not have particulate filters, while most German car models are equipped with them. Here is some relevant information: 1. Function: The particulate filter is a component in the engine's emission system that traps particulate matter in the exhaust, purifying the emissions. Initially exclusive to diesel engines, stricter 'China 6' emission standards introduced limits on particulate emissions, leading to the installation of particulate filters in gasoline engines as well. 2. Risks and Solutions for Clogged Particulate Filters: Accumulation of particulate matter in the filter can lead to clogging, restricting exhaust flow and reducing engine power. The particulate filter requires regular cleaning to remove surface particles. Self-cleaning typically involves raising the filter's temperature to burn off the particles, restoring its filtering performance.
I recently bought a new car and found it equipped with a particulate filter, designed to meet the China VI emission standards. Many cars now come with this feature, such as Volkswagen's Tiguan, Toyota Corolla Hybrid, and some domestic models from Geely and BYD, especially gasoline vehicles produced after 2019. It seems pretty important as it filters fine particles from the exhaust, making the car more environmentally friendly. But I should remind you that it can sometimes get clogged, causing the engine light to come on or increased fuel consumption. Regular highway driving can help alleviate this issue. Although it's a bit of a hassle, it's a good thing for us city drivers to respond to environmental policies. When choosing a car, you can check the vehicle manual or confirm with the sales consultant.
