Does the Nissan Teana have a particulate filter?
2 Answers
Starting from the 2021 model year, the Teana is equipped with a particulate filter, and the overall engine power and torque have also been reduced. The installation location is coupled with the three-way catalytic converter and GPF. A particulate filter is a ceramic filter installed in the diesel engine emission system, which can 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 emissions are subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine exhaust particulate trap through a dedicated pipeline. After passing through the densely arranged bag filters inside, the carbon smoke particles are adsorbed on 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, burning off the adsorbed carbon smoke particles and converting them into harmless carbon dioxide. To check if the Teana has 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 check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it means it is equipped with a particulate filter. Check if there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If there is, that is the particulate filter.
As someone with some knowledge of automotive technology, let me discuss this. The particulate filter is primarily an emission control device designed for diesel vehicles, used to capture particulate matter and reduce pollution. The Nissan Teana in the Chinese market mainly features gasoline engine models, such as the common 2.0L or 2.5L naturally aspirated engines. These types of engines inherently produce fewer particulate emissions, and emission control is achieved through a three-way catalytic converter, eliminating the need for a particulate filter. If referring to overseas diesel versions, there might be rare cases where it’s included, but generally, gasoline-powered Teanas don’t require this at all. For everyday use, gasoline cars are simpler to maintain, with no worries about particulate filter clogging. However, if you’re buying a newer direct-injection model, it’s advisable to check the specifications or confirm with the dealership. In short, the Teana’s emission system is quite reliable, ensuring smooth daily driving.
